- Adult harbor seals can stay submerged for up to 30 minutes, but dives usually last only about three minutes. A two-day-old harbor seal pup can stay submerged for up to two minutes. All marine mammals have special physiological adaptations for diving. These adaptations enable a harbor seal to conserve oxygen while it is under water.

Harbor seals can swim forward and upside-down. They rarely swim backward. Harbor seals can swim up to 19 kph (12 mph), but they generally cruise at slower speeds. Diving. Harbor seals can dive to depths exceeding 200 m (656 ft.). They don't routinely dive this deep, however, since most of their food is found in shallow waters.
May 7, 2021 · Despite living in the same environment and doing largely the same things, seals have evolved two distinct ways to swim. One group of seals chiefly use their feet to propel them through the water, while the other uses their flippers to swim.
May 7, 2021 · Seals and sea lions propel themselves through the water to catch their prey – but true seals (otariids) generally use their front flippers while eared seals (phocids) use their back feet, and...
Sep 26, 2024 · Seals cannot swim as fast as dolphins or whales but are more agile in the water. When swimming, a true seal uses its forelimbs to maneuver in the water, propelling its body forward with side-to-side strokes of its hind limbs.

Adaptations of Seals to the Marine Environment. Seals need to be streamlined in order to move through the water with the minimum amount of resistance or "drag". External structures are absent e.g. ear flaps are internal, limbs are reduced and the male genitalia and female mammary glands are withdrawn into the body.
Feb 9, 2023 · Some species, particularly sea lions, are so flexible they can bend their heads back to meet their hind limbs. While most species swim using their hind flippers, other sea lions and seals use their front limbs for propulsion and their hind limbs for balance and stability.

May 6, 2021 · New research combines cutting-edge engineering with animal behaviour to explain the origins of efficient swimming in Nature’s underwater acrobats: Seals and Sea Lions. Seals and sea lions are fast swimming ocean predators that use their flippers to literally fly through the water.
