Depending on where and what decapods eat, some species can become poisonous to the people that eat them. The pods are thought to discourage predators; they disperse shortly after dusk, as the crabs forage for prey, and form again before dawn. Different species are found in freshwater, seawater, and even inland brines, which may have several times the salt concentration of seawater. 0000177950 00000 n Obtain your shrimp or crawfish specimens (fresh or preserved).

Prepping from sea to table is more of a challenge because the shrimp must be frozen immediately after the catch, whereas crabs and lobsters must remain alive until cooked. The shells are spiky and a bit of a challenge to crack open as it takes table tools to break through the claws and legs. (a.) In the use of common names for species, shrimp is applied to smaller species, particularly species that are dorsoventrally depressed (wider than deep) with a shorter rostrum.
