Yellow-spotted Burrfish

Found singly, during the day under ledges and rocks and in sponges, out foraging for food over coastal reefs and slopes.
Juveniles found in the ocean under weedy rafts.

Porcupinefish spines lay flat, but when threatened they can inflate like a "football with spikes" so the spines are facing outwards to deter prey. The have a plated mouth structure for crushing shells or "fingers".
Can give a nasty bite!
