Psammechinus microtuberculatus, also known as the green sea urchin,[2][dubious – discuss] in the familyParechinidae.[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]
Distributionedit
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]
Habitatedit
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]
Behavioredit
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]
Parasitesedit
Psammechinus microtuberculatus is known to host the following ectoparasites:[5]
Asterocheres minutus (Claus), (1889)
Asterocheres violaceus (Claus), (1889)
