The Strongylocentrotus Droebachiensis translated as "round, pointed", is commonly known as the Green sea urchin. The Green sea urchin is a dull green color with light green spikes, and brown tube-like feet on the bottom. There average size is about from about 50-60mm and reach a maximum of 58mm in size. The organisms are found in rocky shores and deep areas, also in areas of kelp and they live in a moderate area of wave action. They are also found on docks and pilings.There diet consists of kelp and other kinds of seaweed. It will also eat things like muscles, sand dollars, barnacles, periwinkles, sponges, whelks, and dead fish.The way that they eat is, for example, a piece of seaweed lands on them, their tube-like feet will transport it through to their mouth which consists a movable jaw that chews it up into very small pieces and which will become swallowed and then later digested. Kind of like star fish, if a sea urchin's spike falls of it will eventually grow back.The sea urchins walk using their tube-like feet.The tubes use hydrolic pressure of the water vascular system to get around to places. In the 1960's in Nova Scotia, the Green sea urchins had a massive increase in population and the "forests" of kelp were later gone because they had all been eaten.
