The term 'sea crawfish' generally refers to smaller, lobster-like crustaceans that live in the ocean, though it's not a formal scientific term. They're similar to freshwater crawfish but adapted for saltwater environments. Think of them as miniature lobsters, scavengers of the seabed. They're more closely related to lobsters and crabs than true freshwater crawfish. They occupy a similar niche in marine ecosystems as crawfish do in freshwater. They're often more colorful than their freshwater cousins. They can be found hiding among rocks and coral reefs.
