black crow, black periwinkle, eastern black nerite
This thick shell is globular in shape and coloured all black with a white apex on the top. It has a distinctive mouth opening which is semi-circular and white.
Do not take large numbers of nerites because of the risk of local depletion.
Black nerites are very common along sheltered and exposed rocky shores, particularly in the northern part of Tasmania. They are often observed in large numbers hiding in rock crevices or under stones where they feed on algae and sea grasses. Nerites are herbivorous and move about at night feeding on seaweeds.
Although black nerites can be used as bait it is often difficult to extract this small sea snail from its shell meaning a lot of effort is required to bait a hook.
When taken from the rocks the nerite will withdraw its foot and close its operculum. Return it to the rock you collected it from.
