Rock crabs are known to feed on sea snails by crushing their shells through the use of a chela (a nipper or pincer-like appendage).
They are often aggressive in numbers less than five, and are known fin nippers.
Various crustaceans such as nippers, prawns and crabs are commonly used alongside various species of beach and tube worm.
Raw fibre, placed on the in-feed table or conveyor is moved to the nippers which restrain and meter the fibre onto the swift.
In addition to the big shears anchored in a hole in his bench he used hand snips and nippers for cutting.
A rail nipper is used in rail transport modelling to cut rail tracks.
Male gouramis are known to be very aggressive; they may also be fin nippers and generally may bother other fish in the tank.
Cronulla is one of the largest and strongest clubs in the surf life saving movement with 1,200 members, including 620 in its nipper ranks.
