Jun 27, 2023 · Gray seals can swim between 14 to 23 mph, while fur seals can swim up to 15 mph. Every part of a fur seal’s body is covered in fur except its flippers, which help them stay cool in warm weather. However, it also makes them fast and efficient swimmers. Leopard seals can swim at speeds of 25 mph even though they weigh a whopping 1,300 pounds ...

Sep 15, 2007 · Mean `descent' swim speeds were faster than the estimated MCT speed (1.3 m s –1)(Thompson et al., 1993) for all seals except for the adult Q. Mean `ascent' swimming speeds were faster than the calculated MCT speed for all pups (range 1.53–2.00 m s –1), while for adults, ascent swimming speeds were close to or less than MCT speed .

Comparison with Sea Lions. Seals and sea lions are different in how they swim. Sea lions use their long front flippers to swim fast, reaching speeds of 25-30 mph. Seals, like gray seals, swim at a slower pace of 14-23 mph. This shows how seals and sea lions have adapted to their own environments. Species.

Harbor seals swim with all four flippers: they move their hind flippers from side to side to propel themselves forward, and use their foreflippers to help them steer.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.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.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.Before a deep dive, a harbor seal exhales to reduce the amount of air in its lungs. Oxygen is stored in the blood and muscle tissues, rather than in the lungs.Like most other marine mammals, a harbor seal's typical respiration cycle is a short exhalation, a short inhalation, and a longer breath-holding (apnea) period.
Harbor seals sleep on land or in the water. In the water they sleep at the surface and often assume a posture known as bottling - their entire bodies remain submerged with just their heads exposed. This enables them to breathe when necessary.
A harbor seal's core temperature is about 37.8°C (100°F). There is a heat gradient throughout the blubber from the body core to the skin. The skin remains about one degree Celsius warmer than surro...Harbor seals have a metabolic rate somewhat higher than land mammals of the same size. This helps them generate body heat for warmth.A thick layer of blubber insulates the harbor seal, reducing heat loss. The blubber of a northern Pacific harbor seal during winter may account for 27% to 30% of its total body mass. Blubber also s...In cold water, blood is shunted inward as blood vessels in the skin constrict, reducing heat loss to the environment.How fast does a seal swim? Variations in swimming behaviour under differing foraging conditions. / Gallon, S L; Sparling, Carol Elizabeth; Georges, Jean-Yves et al.

Interestingly, all seals swam 10-20% faster on their way to the prey patch compared to the return to the breathing box, despite the fact that any effect of buoyancy on swimming speed should be the same in both directions. These results suggest that the swimming behaviour exhibited by foraging grey seals might be a combination of having to ...
