General aspects

Boxfish are notable for having hard, fused hexagonal scales. This allows them to protect themselves inside a solid frame which gives them the appearance of a box. Due to this protective frame, the movements of boxfish are slow and limited.
Boxfish are a family of fish closely related with puffer fish.

Their skin is hard and covered with small, thorny scales. They are able to inflate their abdomens with water when they are frightened and are able to produce and accumulate toxins.

Which region do they inhabit?

In general, the yellow boxfish lives in tropical seas.

Did you know...?

If they are threatened they can release a toxin which can contaminate the water and poison the inhabitants of the aquarium!
