Hence, the species lends itself well as a model to better understand a variety of processes of the inshore ecosystem. Both shell and spines have a green tint. Müller, 1771).

Psammechinus miliaris occurs in a diverse range of habitats, frequently at high densities, particularly in shallow or littoral locations. EUNIS habitat classification 2012 amended 2019 > A - Marine habitats > A3 - Infralittoral rock and other hard substrata > A3.3 - Atlantic and Mediterranean low energy infralittoral rock > A3.32 - Kelp in variable salinity on low energy infralittoral rock > A3.322 - Laminaria saccharina and Psammechinus miliaris on variable salinity grazed infralittoral rock
The habitat of this species includes rock pools on the shore that can experience quite severe hypoxia or even anoxia.

The tips of the spines are violet. Cet oursin est souvent présent à faible profondeur sous les pierres de la zone littorale. Une population clairsemée de Modiolus modiolus est également caractéristique de cet habitat. The tube-feet are arranged in arcs of 3, visible as 3 pairs of pores corresponding with each ambulacral plate on the denuded test. HABITAT In Scotland P. miliaris typically occurs in dense, localised populations in sheltered areas of sea lochs on the west coast (Davies 1989; Holt 1991) Its distribution frequently coincides with that of the brown macroalga Laminaria saccharina.
Psammechinus miliaris (Gmelin, 1778) Psammechinus miliaris: Description: A regular sea urchin with a somewhat flattened test and green overall colour. It is sometimes known as the green sea urchin or shore sea urchin. Psammechinus miliaris is a species of sea urchin in the family Parechinidae. Psammechinus miliaris must be able to tolerate low oxygen conditions provided the event is brief.
