Psammechinus microtuberculatus, also known as the green sea urchin, [2][ dubious – discuss] in the family Parechinidae. [1] It was formerly known as Echinus microtuberculatus, and thought to be of the genus Echinus. [3]
This is a small, brown, herbivorous [4] 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. [4]
Psammechinus microtuberculatus is found in the western and eastern Atlantic Ocean, the Adriatic Sea and Aegean Sea. [5] It also occurs throughout the entire Mediterranean Sea, though very rare. [4]
This species occurs in the benthic zone at depths of between 1 and 685 metres. [4] It prefers to live near sandy areas, and can be found on hard bottoms of mud or rock. [6]
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". [7]
Psammechinus microtuberculatus is known to host the following ectoparasites: [5]
