That's why they're called the dogs of the sea.
Seals have sharp teeth and just a few weeks ago, a gray seal pup was spotted by a woman on a North Jersey beach. She thought she was helping it when she tried to drag it back into the ocean.
The seal turned and bit her.
Bob Schoelkopf of Marine Mammal Stranding Center says even though the seal was healthy, they had to bring it and quarantine it because it had bit someone.
The woman was treated for the bite and is OK.
The Marine Mammal Stranding Center is trying to get the word out to stay away from beached seals.
It is currently running a new public service announcement.
The center has been getting an average of 3 calls a day of seal sightings.
If anyone finds a seal on the beach or lying on a dock they are urged to call the marine center, which now has a 24-hour hotline, at 609 266- 0538.
