A crustacean trap that includes a collapsible frame assembly surrounded by a collapsible net body. The frame assembly includes a lower collar perpendicularly aligned and attached to a hollow mast. The mast extends upward from the lower collar and slides through an upper collar. Pivotally attached to the upper collar are four radially aligned upper legs. Pivotally coupled to the lower end of each upper leg is a lower leg that is vertically aligned under the upper leg. Each lower leg extends inward and pivotally connects to the lower collar. The upper and lower collars are aligned and registered so when the mast is extended downward through the upper collar, the upper collar and the lower collar separate thereby forcing each upper leg diagonally downward from the upper collar and forcing each lower leg horizontally outward from the lower collar.
