Its members, the malacostracans, display a great diversity of body forms and include crabs, lobsters, crayfish, shrimp, krill, prawns, woodlice, amphipods, mantis shrimp, tongue-eating lice and many other less familiar animals. They are abundant in all marine environments and have colonised freshwater and terrestrial habitats.

1. malacostraca

   Malacostraca is the largest class of crustaceans, a group of primarily aquatic animals including crabs, lobsters, shrimp, krill, and many others. They possess a hard exoskeleton which they periodically shed in order to grow, and the majority breathe through gills. They are characterized by their structure, typically having a segmented body, a pair of antennae, and appendages on each segment for various functions such as locomotion, feeding, and sensory reception. These creatures are found in almost all marine and freshwater environments, with certain species living in terrestrial environments too.
