(Actually, ventral fins are better.) The dorsal’s real function has to do with a phenomenon that most of us have never experienced and many have never heard of—rudder lock. From the pilot’s ...

The ocean sunfish has no ventral and tail fins. What appears to be a tail fin is called a “rudder fin” used to control direction. It can also synchronously move the dorsal and anal fins ...

Yamamoto thinks the unique group of fishing motor neurons found in frogfish suggests that, as a result of evolution, "the ...

Fish use the ventral horn of their ... during the evolution of their function. The motor neurons that perform fishing behavior were originally dorsal fin motor neurons but moved to an unusual ...

“Their location was shifted [during evolution] to serve a role completely different from their original function ... spinal ventral horn, and our ancestors also once had dorsal fins ...

Their dorsal and ventral fins are comprised of flexible bones that are as slender as feathers, hence why researchers proposed the name "Heartfeather Bass." ...
