Banded Sea Urchins are found throughout the Indopacific.

Habitat
Inhabit reef flats and lagoons.

Diet
Banded Urchins feed on algae by scraping rocks and other hard surfaces with their five teeth.

Quick Fact
Small fish (often cardinalfish) frequently hide among banded urchin spines for protection.
