The Black Sea Urchin (Centrostephanus rodgersii) is a very common species found in the temperate waters of south eastern Australia, including Lord Howe and Norfolk Islands. This species can be found on rocky reefs and is rabid feeder and is known to decimate life on rocky reefs turning them into ‘urchin barrens’. This species is known to occur in depths of 0 to 30 metres however it is generally found in waters shallower than 10 metres.

This species is much more active during the night and reefs can turn into a black swarming mass at night when the urchins are moving around looking for food. This species is known to feed on sponges, bryozoans, seaweeds and algae. The spines may grow up to 9cm in length.

The Black Sea Urchin (Centrostephanus rodgersii) is known to grow to a maximum width of approximately 23cm.
