Quick answer
The peacock mantis shrimp is a brilliantly colored crustacean of tropical Indo-Pacific reefs, famous for one of the fastest and most powerful strikes in the animal kingdom. Its club-like front limbs accelerate so quickly that they can crack shells and even break aquarium glass. It also has some of the most complex eyes known, with far more color receptors than humans, and it typically lives 3 to 6 years.

Biology
Peacock Mantis Shrimp (Odontodactylus scyllarus) is classified as Invertebrate with conservation status Least Concern. Typical weight about 0.06 kg; lifespan around 3–6 years.
Ecology
Diet: Carnivore (crabs, snails, mollusks, fish). Habitat: Burrows on tropical Indo-Pacific reefs. Movement and social systems reflect those pressures.
People and this species
Learn before you travel or keep related pets. Wild individuals are not toys; captive care needs species-specific husbandry.

The fastest strike in nature
The peacock mantis shrimp is a smasher that uses club-shaped front limbs to deliver one of the fastest movements known in the animal kingdom. Its strike accelerates faster than a bullet leaving a gun and is so powerful it briefly creates collapsing bubbles, or cavitation, that produce a second shockwave. This lets it shatter the shells of snails, crabs, and clams, and captive specimens have been known to crack aquarium glass.
Extraordinary eyes
Mantis shrimp have some of the most complex eyes in the animal kingdom, mounted on stalks and able to move independently. Where humans have three types of color receptor, the peacock mantis shrimp has around a dozen, and it can also detect polarized light. Each eye can perceive depth on its own, giving the animal remarkable visual abilities for hunting on busy reefs.
Diet and hunting
Peacock mantis shrimp are carnivores that prey on hard-shelled animals such as crabs, snails, and clams, as well as fish. Smashers like this species use their powerful clubs to break open armored prey, while spearing types of mantis shrimp instead impale soft-bodied animals. They are ambush hunters that strike with astonishing speed once prey comes within reach.
Life in a burrow
These animals live in burrows and crevices on tropical reefs, defending their homes aggressively against intruders. They are mostly solitary, though pairs may share a burrow during breeding. Bright body colors play a role in signaling to rivals and mates, and their keen eyesight helps them communicate and avoid dangerous confrontations.
Research notes
Figures for peacock mantis shrimps (Odontodactylus scyllarus) come from field studies, museum records, and conservation assessments that do not always agree on exact averages. Prefer ranges over single-point claims, and check whether a source describes wild, captive, or mixed populations.
Practical takeaways
If you encounter peacock mantis shrimps in the wild, prioritise distance and local guidance. If you care for related domestic or captive animals, match diet and housing to species needs rather than generic pet advice. Share accurate status information (Least Concern) when discussing conservation.
