Quick Answer

Crayfish and their relatives, lobsters, crabs and shrimp, have similar digestive systems that feature two-part stomachs.

Full Answer

Inside the stomach, crayfish have a structure called a gastric mill. The gastric mill helps to grind food items into small pieces. Crayfish consume a wide variety of foods, including vegetative debris, fish and aquatic invertebrates. Crayfish capture food with their large claws before lowering it to their mouths, where they consume it.
