Seal resting on the beach |
Guest Bloggers and in-house volunteers Emily and Melissa were the main contributors to this blog.
It is summertime in New England, which means more
interactions between seals and people as the beaches fill up with swimmers and
sunbathers. Harbor seals and gray seals
are our year-round, native species, and they will rest on the beach to warm up
after foraging in the cooler water.
The majority of seals seen on the beaches are usually less than one year old. They tend to be thinner because they have
weaned from their mothers and are still building up body fat. Due to their young age they tend to be naive to good haul out locations and feeding grounds.
The New England Aquarium’s response area
ranges from Salem, MA, to Plymouth, MA. If
you encounter a seal on the beach within this territory, please call our Marine
Mammal and Sea Turtle Hotline at 617-973-5247. This number can also direct you to other marine mammal hotlines in New England by choosing the correct option.
However to reach a specific marine mammal stranding response agency we have listed geographic areas with the corresponding agency below.
- North of Rockport, Maine: College of the Atlantic - (800) 532-9551
- South of Rockport, Maine: Marine mammals of Maine - (800) 532-9551
- New Hampshire: Sea Coast Science Center - (603) 997-9448
- Salisbury, MA to Beverly, MA (INCLUDING CAPE ANN): NOAA: (866) 755-6622
- Cape Cod and Southeastern, MA: IFAW- (508)743-9548

- Nantucket: NOAA - (866) 755-6622
- Rhode Island and Connecticut: Mystic Aquarium - (860) 572-5944 x107
Every seal reported within New England Aquarium’s territory
will be monitored by the staff and trained field volunteers. Not every seal that is reported will need to
be brought to a facility for rehabilitation.

Seal in banana posture |
This harbor seal is in a normal resting position called the
“banana posture.” Based on the photo, there are no concerns about the health of
this seal.
 |
Resting harbor seal |
Here is another photo of a harbor seal resting on the beach. You can see that he is thinner than the
previous seal. One common concern is
that the seal is a baby that should still be with his mother, but they only
nurse for approximately 4 weeks before they are weaned. This seal is independent and may have just
started learning how to forage for fish.

Harbor seal |
This harbor seal is looking at the photographer. This means that the photographer is too close
since the seal has been alerted by his or her presence. This seal is thin like the previous seal, but
you can see between the rear flippers and in the sand that she has defecated
recently, indicating successful foraging.
 |
Gray seal |
Here is a gray seal in good body condition. The photographer here is too close since the
seal’s mouth is open. Seals can and will
bite if they feel threatened. They can also carry diseases that can be easily transmitted to dogs, as well as humans. This is one of many reasons to keep your distance from a
seal resting on the beach.
 |
Stressed gray seal |
This gray seal is not being shy but is in fact stressed by
the presence of the photographer. Seals will
wave a flipper, scratch their head or cover their eyes if they are feeling
stressed. Seals will also shiver if they
are being stressed. You do not want to put a
blanket on a shivering seal. It may
appear cold, but seals can overheat and die if they are covered.

This gray seal needs help, call the appropriate rescue team |
This gray seal would warrant an immediate field response as
it is entangled with marine debris around his neck.
 |
A gray seal with a head wound needs professional response |
 |
The rescue team wears appropriate safety gear for working with these wild animals |
This harbor seal has a wound on his head that also warranted
an immediate field response. Note that
the New England Aquarium response team is wearing leather gloves, eye
protection, and a face mask due to the diseases that can be transferred between
seals and people.
