    Abstract: A multipurpose marine life container having a closed chamber defined by a pair of substantially identical clam shell-type housing halves opening toward each other and removably joined together along a parting line. An entrance opening is formed in each end wall of the container by a pair of half openings opening toward each other along the parting line. Each end wall supports a rotatable disk that includes three inwardly opening entry funnel areas as well as a closed area rotatable into and out of registry with the corresponding entrance opening. Hollow tubes with air tight closures are removably secured lengthwise through the container to provide buoyancy, weighting and reinforcement for the container. The opposite sides of the container include large openings which are selectively closed by cantilever supported doors swingable by gravity to the open positions and releasably latchable in the closed positions.
