The flippers work in tandem in a way that is similar to a human breast stroke. Unlike the true, or earless, seals (family Phocidae), sea lions and other eared seals (family Otariidae) are able to rotate their hind flippers forward to use all four limbs when moving about on land. Required fields are marked *, Be the first to review “Sea Lion Flippers Pendant: Silver or Gold”. To put her theory to the test, Leftwich used 3D printing to design a man-made version of the sea lion flipper. The sea lion was regulating his body temperature (“thermoregulation”) by floating and raising his flippers out of the water, a behavior called “sailing.” This is often mistaken for injury or illness and even sometimes reported to authorities as an injured orca or other whale. There is a big difference in the length of the flippers. Engraving can be done on the back of the flipper pendant. This feature, along with their strength, lets them support their body weight on all four flippers and walk on land.

When a sea lion “claps,” it stretches its flippers out to the sides and sweeps them down. Based on the joint positions plotted from the video, the scientists proceeded to create an articulated robotic plastic arm (seen below) that moves in the same fashion as a sea lion flipper. Northern seals like grey seals have bear-like paws with large claws, while fur seals and sea lions have very streamlined flippers. The most important thing is that they can rotate their back flippers … Sea lions generate thrust, or forward propulsion, by bringing their fore-flippers together in big sweeping motions called “claps.” When a sea lion “claps,” it stretches its flippers out to the sides and sweeps them down.
