Goniocidaris (Goniocidaris) tubaria is very similar to Prionocidaris callista, these two species of sea urchins occur in the same habitats, especially around Victoria (Australia).
Some sea urchins have very long spines ending in thorny "crowns", others show little more than an irregular surface with a few small stumps.
The spines are usually densely covered with.
Goniocidaris (Goniocidaris) tubaria has large, jagged primary spines, often eroded and covered by sessile invertebrates (algae and other marine life), and plate-like secondary spines that form a corona-like structure around the base of the primary spines.
These starfish occur on coarse gravel and shell limestone covered seabed and on sandy / soft bottoms and rocky reefs to depths of more than 300 meters.
Bathers should always use sturdy bathing shoes in areas with lance-shaped urchins, as spines can easily pierce the skin and cause painful injuries.
