May 6, 2021 · This discovery shows how wing-like flippers can evolve in seals that already swim with their back feet, providing a pathway for the evolution of forelimb swimming in the fur seals and sea lions. “Wing-like flippers help leopard seals to surge forward and ambush fast-swimming penguins,” said Associate Professor Alistair Evans who also ...
May 7, 2021 · There are two main groups when it comes to seals and how they swim. Seals that live predominantly in the northern hemisphere, such as grey and harbour seals, are from a group known as the true seals, or phocids. These have stubby, clawed paws which they can use to manipulate food and propel themselves through the water using their feet.
May 6, 2021 · Even though all seals and sea lions are descended from a common ancestor, they use two radically different modes of propulsion: true seals (phocids) swim with their feet; fur seals and sea lions ...

Nov 24, 2023 · While animals like orcas, sharks, and polar bears have preyed on seals for millions of years, their numbers are growing, and this is impacting seal populations. Much of this is largely due to climate change, which is altering the distribution of predators at the same time as potentially decreasing available seal prey.
May 6, 2021 · Engineers and biologists join forces to reveal how seals evolved to swim Date: May 6, 2021 Source: Monash University Summary: Seals and sea lions are fast swimming ocean predators that use their ...
Dr Travis Park added,’ ‘We found that Grey seals still use their paws to hold their prey when processing it, but other seals like Leopard seals have foregone this ability to maximise their swimming speed and agility, being able to capture more mobile prey.’ As well as explaining the origin of seals, this study may also improve human design.
