Echinoderms / Sea Urchin |
| Phylum: Echinoderms | Class: Echinoidea | Species: Heliocidaris erythrogramma |
| A common reef herbivore, the Sea Uchin usually remains hidden during the day in crevices and under ledges on Victorian rocky reefs. Emerging at night to graze the algae on the rocks, it has a major effect on the abundance and distribution of large algae. | ||
