To move around, the Harbor seal depends on its flippers. The pectoral, or fore, flippers are short and webbed with five bony digits. The digits are about the same length and each has a blunt claw, around one to two inches long.
Seals have shorter limbs than most other mammals. Their limbs have evolved into flippers with true seals having more developed hind flippers and eared seals having more developed fore flippers. A seals eyes are well adapted for seeing both above and below the water.

Fossil records indicate that the ancestors of modern seals first entered the ocean on the west coast, about 28–30 million years ago. Learn more fun facts about seals Learn more about seal ecology and assessment research in the Northwest Atlantic
“Phocid seals” are also called “true seals” and include several species such as harbor seals and gray seals. Phocid seals primarily use their back flippers to push themselves through the water (like rear-wheel drive) and do not have external ear flaps. “Otariid seals” are also called “eared seals” and include all the species of sea lions and fur se...
Seals and sea lions have many well-developed whiskers, much like cats. Like cats, they have a very acute sense of touch. Scientists think seals can use their whiskers to detect vibrations from swimming prey. Blind seals in the wild seem to be able to hunt and feed without sight.
A seal’s body stores enough fat in the blubber layer to allow the animal to go for extended periods of time without eating. In addition, most seals are opportunistic feeders—meaning they will eat whatever is available—consuming a variety of fish, shellfish, and crustaceans. Seals do not eat on land.
Seals and sea lions do not need to be wet constantly. They come out of the water to rest, molt, or care for their pups. Well-intentioned people who find seals on the beach and try to keep them wet are inadvertently harassing the animals, which is prohibited under federal laws and regulations. If you see a seal on the beach, give them space and let ...
Like all marine mammals, seals and sea lions get all the water they need from their food. Their bodies are very efficient at removing and recycling water from their food. They avoid drinking sea water; if a seal or sea lion drinks too much sea water it can become seriously sick. Arctic seals, which spend time on ice, may sometimes eat fresh water i...
For example, a harbor seal’s pelvic bones are fused, preventing them from moving their hind flippers under their pelvis to walk on land. Instead, they move by undulating in a caterpillar-like motion. This does not mean they are injured. Fur seals and sea lions can rotate their hind flippers under their body, which allows them to “walk” on land rath...
Harbor seal pups, one of the smaller species of seals, weigh about 24 pounds at birth and are ready to swim within minutes. They are nursed for 4 to 6 weeks on milk that is 50 percent fat. Northern elephant seal pups weigh 75 pounds at birth, for instance; grey seals weigh 35 pounds.
Northern fur seals have a stocky body, small head, very short snout, and extremely dense fur that ends at the wrist lines of their flippers. Their flippers are the longest in the fur seal family. Their hind flippers can measure up to one-fourth of their total body length. Their fore flippers are incredibly strong, allowing them to walk or run on al...
Harbor seals move their hind flippers side-to-side to propel themselves in water. The hind flippers also function as a rudder. Unlike a sea lion, a seal cannot rotate its hind flippers underneath the pelvic girdle. When on land, a seal moves by bouncing in a caterpillar like motion.
May 7, 2021 · One group of seals chiefly use their feet to propel them through the water, while the other uses their flippers to swim. This is curious, as both groups evolved from the same land-dwelling ancestor that slipped into the sea around 30 million years ago.
Sea lions (and fur seals) are distinguished from true seals by their comparably large front flippers, visible ear flaps, and ability to curl their back flippers under their body to walk on all fours. Sea lions are vocal, expressing themselves in loud barks.
