Save the SEAL - a blog series

It is natural for seals to be in the New England area, and every year we get calls with the same concerns or reactions.  We are starting this blog series entitled 'Save' the SEAL to address the most common statements we hear from the caller.  Before we begin, I want to provide some general information to keep in mind when you see a seal on the beach.  Using a helpful reminder created by a Rescue team volunteer, Mike O'Neill, let's begin!

A gray seal rests on a beach.  They may look awkward on land, but it is a completely natural behavior.

Survey the area by making observations and taking photos from a distance.  Seals are semi-aquatic and are just as comfortable on land as they are in the water.  There is no need to push them back in or approach in any way.  They are wild animals that should be appreciated from a distance. Feel free to take photos, but stay 150 feet away if possible.  Do not jump to conclusions since it is natural for a seal to be on land in this area.

This harbor seal pup was a recent case on the south shore.  People assumed it needed help, and even suggested it was attacked by a shark, when it was actually in decent condition and showing the typical observations we see for a pup, such as being underweight, minor abrasions, and lacking fear of people.  Pups especially may haul out on unusual beaches or act strangely in the water as they learn the best spots to rest and experiment with different behaviors.

Educate on-lookers.  Explain that it is normal for seals to be on land to the people around you!  Now that you know the information, the best way to spread the word is to educate.  No matter how many signs or flyers we hand out, word of mouth is always the best.  You can also help keep a safe distance from the seal which is the best supportive care you can provide for the animal.

Establishing a perimeter a safe distance from the seal is best.  Share the information with fellow beach goers because they probably just don't know the normal behavior of a seal.  Now that you do, you can help spread the word and keep the wildlife wild!

Alert the experts.  If you see a live or dead seal on the beach, call the NEAQ hotline at 617-973-5247.  We are always available by phone, and depending on the situation, we will either respond to an animal ourselves or send one of our highly trained and experienced field volunteers to the scene.  Field volunteers act as our first responders by assessing from a distance, gathering documentation through photos to report back to staff, and educating the public.  They are trained in what to look for such as proper behavior, significance of wounds, and general safety for the animal.

We always try to get a field volunteer to assess an animal as quickly as possible.  If the animal appears healthy or in decent condition, we will leave it on the beach to rest naturally and monitor periodically.  Usually, it is best not to intervene unless absolutely necessary.

Leave it alone.  Seals are not comforted by human presence, and even though they may not retreat from you, it does not mean it is not extremely stressed by the encounter.  Displays such as shivering, vocalizing, and waving flippers are all signs of stress.  Seals are also federally protected by the Marine Mammal Protection Act, which makes it illegal to harass any marine mammal.  Harassment can be defined as anything that will alter the natural behavior, so if a seal is sleeping on the beach, and you approach so that it looks at you, you have altered it's sleeping behavior and technically harassing the animal.  The best guideline is to stay 150 feet away according to these federal regulations.

This harp seal is not waving 'hi', someone must be approaching or making noise.  This behavior is a sign of stress and it is our cue to back away.  Physiological stress can cause a severe decline in health very quickly.

Seals also carry zoonotic diseases, which are pathogens that can be transferred from the seal (including carcasses) to humans or dogs.  Seals can also bite, and the natural bacteria in their mouths can cause severe infections so it is best to keep distance from the seal for you and your pets safety as well.  
                         
We hope this information is useful when you are out on the beach.  Some of the typical comments we get such as "it's a baby and all alone", "it can't get back in the water", or "it was attacked by a shark" and much more will be addressed in blogs to come so remember to follow this series.  In the meantime, remember our hotline # is 617-973-5247 and if you care, leave it there!

Seal Pups on the Beach

Every summer, harbor seal pups come on shore and we must learn to share the beach with them.  Unfortunately for these young animals, as they learn life on their own (it only takes 4 weeks for them to be weaned and completely independent from their mother!), they tend to pick some crowded or awkward beaches to rest on.  The best thing you can do for them is keep your distance and call our stranding hotline - 617-973-5247.   

The majority of the time, seals are just resting on the beach. This harbor seal pup picked some good rocks to rest on. They come out to rest, so don't be surprised if they look tired.

The above harbor seal pup is in very good condition. He is laying on his side and has a good body weight. Unfortunately you can notice someone incredibly close to the animal. Although seals tend not to retreat from humans, our presence, including the sound of our voices, is not comforting.


Above, you can see how stressful it is for a harbor seal pup to rest on this beach. These people are too close! Sometimes you can not always tell externally the extreme physiological stress the animal is experiencing. Since this seal is a pup and still naive, he hasn't figured out the effect this will have on him. It is recommended to stay at least 150 feet away from seals on the beach to limit the stress.

Sometimes seals, like the one above, sustain wounds.  Not all are life threatening though so when you call our hotline, remaining calm and using the best description of the wound is extremely helpful.  We may ask for photos to assess, but you should remember not to get too close.  Seals are protected by the Marine Mammal Protection Act so it is illegal to harass them in any way (anything that will alter their natural behavior).  The above photo shows a seal that was closely approached by the photographer, so he is unable to rest as he would normally do on the beach. 

There are some signs of stress that you can look for. For example, the above gray seal is not waving at the photographer. The flipper movement is a sign of stress and is your cue to back away. Other signs of stress include shivering, vocalizing, yawning, and labored breathing.

Seals should never be covered or have water poured on them.  It is natural for them to be on the beach, and they are able to thermoregulate so you do not want to interfere with that process.  Also, do not offer the animal any food.  Seals are opportunistic feeders and do not eat every day or on land.  Human food is also not appropriate for them. 

Keep in mind sometimes these young pups rest in awkward places, as you can see in the above photo where the seal is resting on the stairs. 
Some people get concerned about seals being on such rocky beaches as well, but it is natural for them to rest on rocks and we are not alarmed when we see some superficial abrasions from the rough environment.
 

Sometimes seals do get in situations we can help with. Can you find the seal in the top left photo? This seal was on a jetty, but as people approached, it went further and further into the rocks. He likely could have gotten out on his own if the area was quiet, but we were able to help him a bit and move him to a quiet beach where he went back in the water (Photo below).




Another case we dealt with last week involved a seal with a fish hook in it's mouth.  The pictures below tell the tale.  The seal came out on a very crowded beach, but luckily some beach goers were able to rope the area off for us.  This gave us time to respond with out the seal being scared back into the water. 

Helpful beach-goers roped off the area around the injured seal.
You can see the fish hook in the seal's mouth.

Seal returns to the ocean on its own
We were able to remove the fish hook fairly easily.  We cleaned up the wound, which wasn't as severe as you would expect, and relocated the seal to a quiet beach where it could get the rest it needed to heal.  Or in this case it went back in the water (photo above).  This article from the Newburyport Daily News explains how everyone, including state police and the public, came together that day to make a bad situation have a good outcome.

Relocating a seal is a last resort as this process is also very stressful for an animal.  So remember, always keep your distance and share the shore with the seal pups on the beach!

As you can see, seals are keeping us pretty busy these days. You can read past posts here on what to do when you see a seal on the beach. But we also have some turtles still in our care.  

Don't forget about the Live Webcast On Wednesday July 18th at noon to see our sea turtle patients and get an update on the rescue department activities. I hope to see you there!

Local seals and their natural behavior: When not to intervene

As another BUSY seal pupping season has come to an end, the fine folks here at the New England Aquarium’s Department of Rescue and Rehabilitation thought it necessary to touch on a few points to bring the season to pleasant closure. First we will review some basic facts about some of our resident marine mammals, then we’ll touch on some key points to take away from this busy season we’ve all had.

First things first, what types of seals will New Englanders, and tourists, most commonly see during these summer months?

Even though there is a strong bond between mother and pup, harbor seals for the most part do not show affinity to be in close contact with other harbor seals. However, during molting season which is between spring and fall, they are often found congregating together on sandy and rocky areas in addition to various kinds of intertidal zones. They can be found sleeping, scratching, lounging, as well as scanning the area for potential threats of predators. It is common and natural to find a seal pup alone out of the water hauled up on shore. It is here that the young pup, usually still nursing, rests as it waits patiently for its mother to return from feeding.

Harbor seals will nurse their pups for roughly four weeks, and after that are abruptly weaned from their mothers. At this point, the seals are left to fend for themselves. This is a very stressful time for these young seals, and why it is especially important to allow them to rest undisturbed!

Approaching a seal, regardless of age, places the animal and the approaching person in danger. Stress to these creatures puts them at greater risk of prolonged illness and injury. If you should happen to see a seal resting on shore, it is important to stay at least 150 feet away. The Marine Mammal Protection Act of 1972 states that anyone is in violation of this Act if their presence changes the behavior in any way of a marine mammal. We therefore recommend people to stay at least 150 feet away, and depending on the behavior, even further.

The strandings of whales, porpoises and dolphins should not be confused with seals coming on shore. The response methods used for different marine mammals varies according with species. For instance, responding to a stranded dolphin or other cetacean, which should never come ashore, will be very different than our response to a seal, which commonly rest on shore.

This young harbor seal, seen above, is resting on a rocky shore. It does not appear to be in need of assistance. The best approach is to monitor the seal at a safe distance. There is no need to intervene, since that will cause unneeded stress.



The above picture shows beach goers sitting and congregating TOO CLOSE to a resting seal pup. What these children and most people do not understand is that their presence puts this pup in danger. If this pup were still nursing, mom would not approach if people or other predators were present. Mom will often abandon her young when danger is present and if that happens, it will lead to the pup not getting the nourishment needed and possibly cause its demise. The physical presence of humans, any physical contact or placing yourself between the animal and its perceived escape route back to the water are all very stressful situations for these animals. If there are pets present, that too will contribute to increasing the seals stress and put its survival at risk.



For the safety of beach goers and their pets, it's important not to come in contact with these animals. Not only is it illegal to make physical contact, but seals are also capable of transmitting disease to other mammals they come in contact with. This includes dogs as well as people!

The harbor seal pictured above is aware of the person taking its picture. The photographer is quite a distance from the seal, and the seal appears to be relaxed based on the “banana posture” of its body.



This photographer is TOO CLOSE to this young gray seal. The footprints surrounding this animal are an indication that people were interacting with this animal. Gray seals are known to act aggressively, and they will often growl and vocalize when they feel threatened, as shown in the picture above.

NOW FOR A FEW TAKE HOME MESSAGES! • Seals rest on shore. This is perfectly normal behavior for all seals, young and old. Wouldn’t you be tired too if you were swimming in the ocean all day?
• While they are resting, they need to be left alone! Do not try to feed, touch, or pose with these animals for pictures. Remember, harassment is anything that changes the natural behavior of the seal.
• If a seal truly is injured, don’t touch it or try to help it! Call the Marine Animal Hotline immediately.
617-973-5247
Keep the WILD in WILDlife. Enjoy the presence of these native animals from a distance.

This blog was created by our wonderful Wednesday volunteers, Diane and Deidre. Thanks to them, and to all the rest of the volunteers for their hard work with the Rescue Department!

I See Harps... They're Everywhere!

It's that time of year again. As the temperature drops our Arctic friends once again return to Massachusetts beaches. You can see in the photo above a seal in Rockport, MA that was monitored by the Whale Center of New England (WCNE).

Why are these seals called harp seals? At some point in time, people thought the black pattern on their back resembled the musical instrument (I don't see it). One of our field volunteers, Patty, took the above photo.

As we have mentioned in previous posts these animals are protected by the Marine Mammal Protection Act. It is against federal law to get too close (closer than 150 feet), harass or change the behavior of the seals in any way.

Above left the seal is not waving hello. This is actually a sign of stress and that you are probably too close. NEAq staff and trained field volunteers will do what is called a "close approach" to these animal to look for signs of injury or assess activity/behavior of the animal. It is also illegal to allow your pet to approach these animals, too (above right). Seals are wild animals that can carry disease that may be transmissable to your pet and you. They also have sharp teeth and claws that they will use if threatened.

One defensive mechanism harp seals often utilize is to "play dead". The seal in the photo above on the right is a juvenile seal, which is using this defensive technique as the dog approaches. Keeping pets on a leash this time of year on the beach is always a good practice to avoid these interactions.

Above is a more typical view of these "ice seals." You will find them resting and enjoying the ice and snow in the arctic. The above photo was taken in Hull by the reporting party. These seals along with some other arctic seals are born on pack ice, which is why they are sometimes referred to as ice seals. They do not get stuck to the ice, and all seals are semi-aquatic which means they also spend time out of the water on land, ice or snow. It is not uncommon to have a seal spend several tide cycles out of the water in the same spot.

This seal in the photo above was resting in a marsh in Essex, Mass. Another adult harp seal!

We don't see many adult harps on Martha's Vineyard but the above photo is one of several that we have monitored in the past weeks on the island.

Above was a seal that was in Marblehead today.


If you see a seal, please call our hotline at 617-973-5247 and leave a message. We will return your phone call as soon as possible. (There are many groups that respond to seals. The Aquarium responds in New Hampshire and Massachusetts from the NH boarder down to Sagamore, Mass. We also cover the Islands. IFAW covers the mainland Cape Cod, {maybe we'll work on a map for you with all the corresponding phone numbers you'll need!})


Some tips on leaving messages:
  • Stay calm!
  • Clearly state where the seal is. Give town name and what beach the seal is on. Also if there is a close address give that too.
  • We will need your phone number to call you back. Slowly state your number.
  • Give us some comments on the seal. Is it lying on it's side or vocalizing...

Most importantly enjoy the moment from a safe distance!

All of the seals mentioned above have done what this seal (below) was doing: returning to the ocean.



Another seal heads back in to the water. Possibly returning to the Arctic, or maybe it will stop off in Maine and visit our stranding partners to the north before heading home to Canada!

Seal Pup Season

Harbor seal pup season has arrived so I thought I would give you an update on what the rescue team has been doing in the field and a reminder of what to do when you see a seal on the beach.

This past week has been fairly busy in the field now that pups are here. We have transferred two pups to the University of New England (UNE) Marine Animal Rehabilitation Center this last week. The first one was a pup in Winthrop. I actually was playing field volunteer that day and went down with one of our interns to assess the animal in the morning. The seal appeared to be resting on the beach. A few wounds were noticeable and the seal was quite thin, but overall behavior was decent.

The harbor seal pup during our morning observation.

We went back to check on the seal in the afternoon and there was a noticeable decline in behavior. The seal's posture was poor (laying flat) and I noticed the right rear flipper was swollen, among other things. I decided to collect him and he was transferred to UNE.

You can notice the difference in posture from the morning pictures and these afternoon pictures.

The second seal was down in Duxbury this week and it had multiple wounds. It had been going in and out of the water and moving to different locations on the beach. The wounds were a bit concerning for us so the next day when he was spotted, the Duxbury Animal Control Officer and one of our field volunteers were able to kennel him for us. I then met them and did an exam on the seal. Most of the wounds were infected, his breathing was poor, and he was very lethargic. He was also transferred to UNE for care.

In the photos above you can see some of the wounds and the discharge from the nostrils of the seal pup in Duxbury.

Seals are protected by the Marine Mammal Protection Act, which makes it illegal to touch, harrass, or alter their normal behavior in any way. For information on what to do when you see a seal on the beach, check out Adam's post from last year. And remember to call our stranding hotline 617-973-5247!

Another seal in Winthrop

On Saturday morning, I received a call about a seal in Winthrop. One of our field volunteers went to check on it immediately and found a healthy harp seal resting on the beach. Everything seemed pretty quiet throughout the day and our volunteer checked on it multiple times, but by 4pm more people on the beach meant more people approaching and harassing the seal. It is normal for seals to rest on the beach and they are protected by the Marine Mammal Protection Act, which means harassing (any disturbance that will alter normal behavior including approaching, loud noise, feeding, etc.) seals is illegal. Unfortunately people started trying to pet the seal (one person almost got bit) and get it back in the water, but this does more harm than good. Here are more tips on what to do if you come across a seal on the beach.

At 4:30p I dispatched our field volunteer back out to assess the situation. She reported back that she was able to control the scene, but there were lots of people around. I asked another field volunteer to help her while a team and myself gathered our gear and headed up there.

I examined the animal and assessed that it was fairly healthy and resting on the beach. He did seem extremely stressed since he was shivering and waving his flipper at me, both of which are stress responses. I retreated back to a safe distance so that he would relax and made a plan to relocate the seal to a more remote location where he could get the rest he needed.

We decided to kennel the seal and release it on a quiet beach. Relocation is a last resort because it is an extremely stressful situation for the animal as well. The best thing would have been for it to get the rest it needed on the beach without human interference. I marked him with an orange dot prior to release so that we would be able to identify him if he came up on another beach. He ended up going back into the water, and likely found another (and hopefully quiet) beach to rest.

This is not the first time a seal in Winthrop drew a crowd. Check out this previous post to see how rescuers handled a very similar situation.

Stranded Dolphin in Revere

On Tuesday, the rescue team responded to a live dolphin. At around 4:30pm, Adam received a report of an animal, what was originally believed to be a harbor porpoise, swimming just off shore of Revere Beach. The description seemed to be the behavior of a porpoise feeding close to shore, which is normal for this species. While getting more information on the animal, it then beached itself.

Unfortunately, onlookers decided to push the dolphin back in the water in hopes that it would swim back out to sea. If a dolphin strands, it is best not to push it back in the water. Keep your distance and call our stranding hotline immediately. (Here are more tips on what to do if you encounter a stranded marine animal.) This animal ended up repeatedly beaching itself after multiple attempts to be put back in that water by onlookers, causing a great deal of stress on the animal. Luckily, the Revere Police Department arrived on scene and was able to keep people away while the rescue team was on their way.


Adam provides supportive care to the Atlantic white-sided dolphin on Revere Beach.

The animal was in the surf zone at this point and we gave permission and instructions to an individual in a wet suit to support the animal so it would not continue to be pushed around by the waves. When the rescue team arrived on scene, we were surprised to find out it actually wasn't a harbor porpoise, but a juvenile Atlantic white-sided dolphin!

The dolphin was placed in a stretcher and carried off the beach by Rescue staff and volunteers to a quiet and less stressful location for the animal.

This species is very social and would not survive without its family group. Adam used binoculars to search the open water to see if other dolphins were in the area just in case, but none were seen. If brought out to the ocean with no other animals of its species, it would not survive. The animal was brought back to the aquarium to run blood work and continue an examination. After determining this animal was in very poor condition, extremely thin and labored breathing, it was humanely euthanized.

The rescue team performed a necropsy on the animal the next day to find a cause for the stranding. There was nothing obvious to determine the cause, and pathology is pending.

A special thanks to the Revere PD for their help in this case!
