Knowra Stomatopoda Stomatopoda Stomatopoda is an order of marine malacostracan crustaceans commonly called mantis shrimp. Its members have specialized raptorial appendages and are distinct from decapods such as crabs and true shrimps.
Raptorial appendage : A specialized appendage that captures or strikes prey with rapid, forceful movement. Stomatopods use one of these paired limbs to spear or smash prey.
Malacostraca : The largest class of crustaceans, including crabs, lobsters, krill, and mantis shrimp. Stomatopoda is one order within this broad crustacean class.
Biological impact mechanics : The study of how living systems produce, transmit, and withstand rapid impacts. Stomatopod strikes offer a biological example of extreme underwater impact.
Peacock mantis shrimp : A colorful Indo-Pacific stomatopod, Odontodactylus scyllarus, known for a powerful smashing appendage. It is a widely studied example of a smasher stomatopod and its impact-resistant club.
Smasher stomatopod : A mantis shrimp that uses a club-like raptorial appendage to break hard prey or strike threats. Smashers represent one of the order's two principal prey-capture strategies.
Mantis shrimp strike : The rapid attack produced by a stomatopod's spring-loaded raptorial appendage. This strike can deliver exceptional acceleration and generate cavitation bubbles in water.
Crustacean : An arthropod of the subphylum Crustacea, typically bearing two pairs of antennae and branched appendages. Mantis shrimp share the defining arthropod and crustacean body plan.
Biomimetics : The practice of applying biological structures or processes to engineered designs. The impact-resistant clubs of some stomatopods inspire research into damage-tolerant materials.
Pistol shrimp : A snapping shrimp that creates a cavitation bubble by rapidly closing an enlarged claw. Like stomatopods, it produces cavitation, but with a claw rather than a raptorial limb.
True shrimp : A common name for decapod crustaceans in groups such as Caridea and Dendrobranchiata. True shrimp are decapods, whereas mantis shrimp are stomatopods.
