Crazy Fish Heads

Epibulus insidiator, the slingjaw wrass, “possesses the most extreme jaw protrusion ever measured in fishes.” Individuals can protrude their jaw up to half the body length to capture crabs, shrimps, and small fishes.   This occurs through multiple structural novelties, as the video above can attest to, involving fundamentally reorganizing the way the bones and ligaments interact in the jaw linkage (Westneat 1991).

At the American Museum of Natural History website, you can view and interact with fish skulls that illustrate how the bones move in this process.
