Overview

Found singly, often resting in large sponges during the day, over mud and sand bottoms, of clear, protected reefs, rich in algae and sponge growth.
They feed nocturnally on hard shell invertebrates.
Widespread South East Atlantic, Indo-West Pacific

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!
