Where do stomatopods, also called mantis shrimps, usually live?

Stomatopods, commonly known as mantis shrimps, are members of the class Malacostraca and the order Stomatopoda. Contrary to the broader distribution of many other malacostracan crustaceans, which inhabit diverse environments ranging from terrestrial to deep-sea habitats, stomatopods are largely confined to tropical marine shallows.123

While they are a widely distributed group, they primarily occur in coastal waters, though some species have been found at depths as great as 1,300 metres. Many species live in burrows, and they are known to inhabit various substrates, such as muddy bottoms or areas with organic debris. As excellent swimmers, both adults and larvae are well-adapted to their marine environments.1
