Did you know crayfish are freshwater crustaceans closely related to lobsters—and they’ve been around since the Triassic period? Found in rivers, swamps, and even paddy fields, they breathe through feather-like gills and thrive best in clean water. Crayfish eat plants, animals, and even detritus like mud and biofilm, and some species are so tough, they survive pollution! You’ll find the greatest diversity in North America, especially Louisiana—where crawfish are a cultural icon. In Australia, giant crayfish can weigh over 5kg! Oh, and the study of crayfish? That’s called astacology.
