A whale’s eye is roughly the size of a grapefruit. The flipper is equivalent to the human hand and arm and is used for turning. Humpback whales have large flippers which they use for locomotion. The tail flukes are lobes on a whale’s tail and are the primary structure used for swimming.
What body parts do whales use for survival?
Among these adaptations are: streamlined bodies for efficient movement through water; forelimbs modified into flippers to aid in steering; hind limbs internalized remnants reducing drag; tail positioned horizontally to achieve a powerful up and down propulsion; hair replaced with under-skin blubber to provide warmth ...
Does a whale have fins or flippers?
Whales generally have four fins : two pectoral fins (instead of arms), a caudal fin (also called the tail) and a dorsal fin. The caudal fin is used for propulsion of the animal, with up-and-down movements created by powerful muscles along the peduncle. The two pectoral fins serve as the whales’ rudders and stabilizers.
What is the back part of a whale?
Tailstock : also called caudal peduncle, the tapered rear part of the body, from just behind the dorsal fin to just in front of the flukes. Toothrake: The parallel rake-like scars that can be left on a whale or dolphin’s body, dorsal fin, or tail flukes after being bitten by another (toothed) whale or dolphin.
What are whale arms called?
A flipper is a broad, flattened limb adapted for aquatic locomotion. It refers to the fully webbed, swimming appendages of aquatic vertebrates that are not fish. In animals with two flippers, such as whales, the flipper refers solely to the forelimbs.
What’s the difference between flippers and fins?
Fins have no true bones or skeletal structure within and are composed primarily of cartilage. A flipper has a bone structure as well as cartilage, joints, and tendons.
Can sharks survive without fins?

What is whale skin made of?
Blubber is a thick layer of fat, also called adipose tissue, directly under the skin of all marine mammals. Blubber covers the entire body of animals such as seals, whales, and walruses—except for their fins, flippers, and flukes.
Is whale a fish or mammal?

How is the whale flipper like a human arm?
The flipper of a whale, the wing of a bat, and the leg of a cat are all very similar to the human arm , with a large upper “arm” bone (the humerus in humans) and a lower part made of two bones, a larger bone on one side (the radius in humans) and a smaller bone on the other side (the ulna).
