Why is the peacock mantis shrimp's punch so famous?

It snaps its club-like raptorial appendage at speeds up to 80 km/h, generating enough force—and cavitation bubbles—to shatter snail and clam shells, and even crack aquarium glass.

How good is its eyesight?

Each compound eye carries 12 types of photoreceptors, far more than the three humans have, allowing it to see ultraviolet and circularly polarized light.

Peacock Mantis Shrimpモンハナシャコ

Odontodactylus scyllarusLC— Least Concern

The peacock mantis shrimp is a large, brilliantly colored stomatopod found on Indo-Pacific coral reefs from East Africa to Japan and Australia. It is famous for its raptorial claws, which deliver one of the fastest strikes in the animal kingdom to smash open the shells of snails, clams, and crabs. It is currently assessed as Least Concern and remains common across its range.

Did You Know?

Its raptorial appendage strikes at up to 80 km/h (50 mph)—among the fastest strikes in the animal kingdom—generating over 1,500 newtons of force and cavitation bubbles that deliver a second shockwave. Source
Its compound eyes contain 12 types of photoreceptors (versus three in humans) and can detect circularly polarized light, a trait studied for optical technology. Source
