An active Trumpetfish (Aulostomus maculatus) displaying a yawning behaviour where the jaw extends open and out, widening the mouth considerably. This is typical of many fish, especially predators.

This vertical position serves several purposes. As a defensive position it allows the fish to hide inamongst sea rods and other corals, which can also allow for an ambush attack in certain circumstances. As an offensive tactic it is thought to also allow a better view of its prey, which tend to be smaller marine creatures that live on coral reefs.
