Semi aquatics have webbed feet, sea turtles have flippers and terrestrial tortoises have elephantine legs. Aquatic turtles use flippers and webbed feet to paddle while swimming underwater.
What is a humpback fluke?
Humpback whales often show these tails, or ‘fluke’ while diving, making them ideal candidates for photo-identification projects. Of all the baleen whales, humpbacks are most likely to engage in surface activities such as breaching and slapping their tail flukes and pectoral fins.
What is an orca tail called?
A whale’s tail is called its flukes. … Flukes move up and down to propel the whale through the water. (This is unlike fish tails which move left and right.) Flukes have no bones in them. They are made of muscles and dense fibrous tissue.

Over time their descendants spent more and more time in the water and their bodies became adapted for swimming. Their front legs became flippers and a thick layer of fat called blubber replaced their fur coats to keep them warm and streamlined.
Which animal has got flippers and webbed feet?
The semi-aquatic mammals, such as otters and platypus, have physical adaptions for swimming such as webbed feet whereas the fully aquatic mammals such as whales and dolphins, manatees and seals have limbs and tail modified into flippers or fins.
Which animal has flippers instead of legs?
Whales are the world’s biggest animals. They look like fish, but are warm-blooded mammals that breathe air with their lungs. They have flippers instead of arms or front legs, which they swim with.
