[1] Caenocentrotus gibbosus has a rounded, slightly flattened body covered with spines that provide protection and aid in locomotion.
The spines are often varied in length and coloration, which can help the species blend into its surroundings to avoid predators.
This species inhabits shallow marine environments, typically found in rocky or coral reef areas.
It thrives in tropical and subtropical waters, where it contributes to the ecosystem by grazing on algae and detritus, helping to maintain the balance of the marine habitat.
As a grazer, Caenocentrotus gibbosus plays a significant ecological role by controlling algae growth, preventing overgrowth on reefs, and promoting coral health.
