Pectoral or Flippers
Fish with pectoral fins use them to swim around, much like you would use flippers on your feet in the water
They get thier milk from under thier mothers front pectoral flippers. The glands are under there.
The tail fins are 'flukes'. Otherwise the fin on any marine animal is "... fin" where "..,." is the adjective denoting its position on the body.
Walruses can rotate their back flippers and use them for movement on land.
Flippers in fish, also known as fins, are used primarily for stability and maneuvering. The pectoral fin can help fish dive, climb, turn left or right as well as back up. The pelvic fins help the fish maintain an upright position while swimming and the tail fin is responsible for forward movement and speed.
The rear flippers of a whale are called flukes. They are broad and flat, and are used for propulsion and steering while swimming.
About 8,000 pounds and 28 feet long these Dolphins (Yes they are not in the whale family they are Dolphins) have 2 Pectoral fins (flippers), 1 upright dorsal fin and 1 fluke (tail)
Propulsion and stability.
Penguins do have well-developed pectoral muscles, which are crucial for their swimming abilities. These muscles enable them to use their flippers effectively to propel themselves through water, much like how birds use wings for flying. However, compared to flying birds, penguins' pectoral muscles are adapted for endurance and power in a submerged environment rather than for flight. This adaptation allows them to navigate and hunt efficiently underwater.
The descriptive features of the humpback whale include two blowholes and notched flukes (tail). The pectoral fins are 1/3 the length of the animal and are the largest flippers of any whale.
No, they are called Megaptera Novaeangliae, (Latin) or long winged New Englander, by the whalers for their very long pectoral fins, the longest fins of any whale.Read more: Do_humpback_whales_really_have_the_nickname_wings_of_the_ocean
