yabby pump

Noun

 * 1)  A large hand-operated syringe-like suction pump, made of metal tubing with a rubber plunger, used to harvest ghost shrimp (prototypically the marine yabby) and other burrowing crustaceans from intertidal environments.

Usage notes

 * As a common name for ghost shrimp, the basic term yabby remains restricted to eastern Australia. However, the compound yabby pump has become widespread among carcinologists who have adopted the device in many areas of the world as a means of capturing littoral burrowing crustaceans for study.
