Unique seal swimming patterns could inspire new underwater drones This competition is now closed Unique seal swimming patterns could inspire new underwater drones Advertisement While biologists have long known that seals and sea lions have had two different methods for swimming, the reason behind this has been a mystery. By using cutting-edge engineering alongside footage of animal behaviour, scientists can now explain the origins of efficient swimming in the animals. Seals and sea lions are fast-swimming ocean predators that use their flippers to “fly” through the wat...

How seals adapted to move through water Collaboration of zoologists and engineers solves seal “evolutionary riddle”. Have you ever wondered how seals learned to perform their skilled underwater acrobatics? Zoologist David Hocking, formerly of Monash University and now curator of vertebrate zoology and palaeontology at the Tasmanian Museum and Art Gallery, did, and says he has now helped “to solve an evolutionary riddle at the heart of seal evolution”. Seals and sea lions propel themselves through the water to catch their prey – but true seals (otariids) generally use their front fli...

Share 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. But not all seals are the same: some swim with their front flippers while others propel themselves with their back feet. In Australia, there are fur seals and sea lions that have wing-like front flippers specialised for swimming, while in the Northern Hemisphere, grey and harbor seals have stubby, clawed paw...

Few fish can outswim a seal. Seals fly through the waves, predators in their natural element. But, unlike fish, seals are air-breathing mammals whose ancestors only returned to the water from a life on land some 30 million years ago. On entering the water, seals had to adapt both their bodies and behaviour to become efficient underwater swimmers. Like penguins and sea turtles, they use streamlined limbs to propel themselves through the water. Yet, there is a mystery here. Even though all seals and sea lions are descended from a common ancestor, they use two radically different modes of propu...
