ABSTRACT:
A pneumatically operated device for collecting biological specimens under water in a receiving chamber and employing a pneumatically operated plunger for creating suction at an intake to the receiving chamber is provided with a nozzle having a movable end remote from the intake. A pneumatic nozzle activator is operated in tandem with the plunger to extend the movable end of the nozzle away from the intake and toward a live biological specimen to be trapped. Concurrent retraction of the plunger and extension of the movable nozzle end toward the specimen, enhances the likelihood of a successful capture. A specimen collecting container may be coupled to the receiving chamber, and flapper valves within the nozzle, at the receiving chamber intake, and at a specimen collecting port leading to the collecting container facilitate the direction of the specimen into the collection container while reducing the likelihood that the specimen will escape.
