Psammechinus microtuberculatus, also known as the green sea urchin,[2][dubious – discuss] in the family Parechinidae.[1]

Description[]

This is a small, brown, herbivorous[3] sea urchin nearly spherical in shape. It has with short spines greenish or whitish in colour. It grows to a maximum diameter of 5 centimetres.[3]

Distribution[]

Psammechinus microtuberculatus is found in the western and eastern Atlantic Ocean, the Adriatic Sea and Aegean Sea.[4] It also occurs throughout the entire Mediterranean Sea, though very rare.[3]

Habitat[]

This species occurs in the benthic zone at depths of between 1 and 685 metres.[3] It prefers to live near sandy areas, and can be found on hard bottoms of mud or rock.[5]

Behavior[]

Psammechinus microtuberculatus is capable of protective camouflage. Under hypoxic conditions, it has been observed to discard its "protecting camouflages when confronted with low DO [dissolved oxygen] concentrations" in order "to increase mobility and/or reduce oxygen demand".[6]

Parasites[]

Psammechinus microtuberculatus is known to host the following ectoparasites:[4]
