Dolphin flippers are called pectoral flippers which are forelimbs that are used for allowing the dolphin to steer and maneuver in the water.
Dolphin flippers also have a similar skeletal structure to the human hand which are supported by stiff connective tissue.
A sea flipper is a broad and flattened limb that is adapted for aquatic locomotion in sea animals.
The sea flipper refers to the fully webbed swimming appendages of aquatic vertebrates that are not fish.
In animals that have 2 flippers like whales the flippers are the forelimbs.
Flippers are also distinct from fins, that are the hydrodynamic structures which are found on fish.
And flippers are also evolved tetrapod limbs, whereas fins are cartilaginous or even bony structures that are developed for aquatic locomotion.
Flippers are also derived from the limbs of tetrapods "land animals" and fins are specialized structures in fish.
Flippers often also have bones and fins in fish are mainly composed of cartilage.
Whale flippers, seal flippers and sea turtle flippers are some examples of flippers, and shark fins, fish fins and the tail fin or fluke of a whale are examples of fins.
In the water, the fore flippers of a seal are used for steering.
The webbed hind flippers of a seal also have five bony digits.
But the outside bones are longer and wider then the inside ones.
Moving the hind flippers from side to side propels the Harbor seal through the water.
