When a mantis shrimp (Crustacea: Stomatopoda: Odontodactylidae: Odontodactylus scyllarus) strikes at extreme speeds, cavitation forms between the appendage and the target. Cavitation itself causes extremely high pressure when the...

A peacock mantis shrimp (Crustacea: Stomatopoda: Odontodactylidae: Odontodactylus scyllarus) strikes a force sensor with its raptorial appendage. This video is a close-up view of the mantis shrimp's "hammer" (the dactyl) and was...

A peacock mantis shrimp (Crustacea: Stomatopoda: Odontodactylidae: Odontodactylus scyllarus) uses its raptorial appendage to strike snail shell. Because of the extreme speed of the strike, a sheet of cavitation forms over the...

Trap-jaw ant mandibles close at extremely high speeds. This movie was filmed at 50,000 frames per second and is played here at 30 frames per second. It shows a dorsal view of the mandibles closing onto a thin wire.

This peacock mantis shrimp (Odontodactylus scyllarus) uses its hammer-shaped appendages to smash open hard-shelled prey. This is a "regular speed" video showing an individual successfully opening a snail shell.

Jaw jumping in trap-jaw ants can be elicited through "dangerous" situations, such as when an intruder enters the arena. This ant aims its jaws toward the ground and launches itself into the air. Filmed at 3000 frames per second, played back...

Trap-jaw ants (Odontomachus bauri) can launch themselves into the air to escape potential predators or aggressive intruders. This ant aimed its jaws toward the substrate and launched itself into the air. Filmed at 3000 frames per...

Trap-jaw ants can toss each other away during fights. This video shows two different species of Odontomachus trap-jaw ants fighting. Filmed at 3000 frames per second, played here at 30 frames per second.
-
This trap-jaw ant (Odontomachus bauri) fired its jaws against a pair of forceps and launched itself into the air. Filmed at 3000 frames per second and played back at 30 frames per second.
