What is the difference between shark and dolphin fins?

Dolphins and sharks both have dorsal fins on their backs, two pectoral fins on their sides, and a tail. Sharks’ tail fins are vertical and they use them in a side-to-side motion to swim, while dolphins’ tails are horizontal and they use them in an up-and-down motion to swim.

What is the caudal fin used for?

The tail fin (called the caudal fin) is the main source of movement for most fish. It’s like the motor on a boat. It shouldn’t be surprising then, that it is shaped differently according to how the fish needs to move most of the time. This helps the fish to move more efficiently through the water.

How do sharks use their fins?

A recent study showed that the lunate-shaped caudal fin of lamnid sharks originated in the heterocercal caudal fin (Kim et al., 2013 ). In general, the evolution of morphological features is based on modifications in developmental processes (Moczek et al., 2015 ).
