Oplegnathus punctatusis commonly referred to as Spotted knifejaw. Difficulty in the aquarium: There are no reports available yet that this animal has already been kept in captivity successfully. Toxicity: Toxic hazard unknown.
Oplegnathus punctatus belongs to the family of billfishes also called knife-jaw fishes.
The name "knife-jawed fish" is derived from the fact that the teeth of adults have grown together to form a parrot-like beak.
This hard beak is used to crack and bite the hard-shelled prey of the razorback.
A good distinguishing feature between billfish and parrotfish is the difference in body scale sizes, which are much smaller in billfish.
Beaked perch are kept in aquaculture, fished commercially and are also popular with sport fishermen.
