two orca fins

As Finn (more rarely dorsal fin called) refers to the dorsal fin of sharks and whales .

The fin has a very characteristic triangular shape and is primarily used to stabilize the movements of the fish or whale. The fin is an important identification feature, as the type of shark or whale can be determined on the basis of position and size, shape and color. In addition, the Finns can also be used to distinguish between individuals of the same species.

From a tribal point of view, the external resemblance of the Finns of sharks and whales is an analogy ; H. a parallel development due to similar environmental conditions.

In Asia , shark fins are considered a delicacy . The separation (the so-called " fins ") of the fins happens, for example, in the Maldives while still alive.
