Hawaiian Triggerfish and — Linkage Mechanisms?

A rather baffling creature name is the triggerfish, but it has nothing to do with shooting. It has to do with spines. It has a larger dorsal spine that is locked upward by a smaller trigger spine. This can help it stay put in a hiding place, then it can "deflex" to release the trigger spine and then the dorsal.

Hawaii's Reef Triggerfish is officially the state fish. It has an interesting jaw mechanism that defies evolution with its specified complexity. Humans use industrial linkage mechanisms to transfer energy, and this triggerfish has something similar in its jaw.

Everything in the assembly has to work, or the fish will not be able to work its jaw and become extinct. It all has to be there are working. Actually, other animals have similar mechanisms. This testifies to the design work of the Creator. Another testimony is how the system in the triggerfish can adapt over generations. Yippie ky yay, secularists!

Hawaiians call their state fish the humuhumunukunukuapua’a, or humuhumu for short, and snorkelers marvel at its wild paint job as it flits beneath basalt reefs. Scientifically named Rhinecanthus rectangulus, it is one of a variety of triggerfish that are named for a “trigger” used to lock the dorsal spine in an “up” position. Two aspects of the wonderful humuhumu reveal its Creator’s handiwork.
