Green Sea Urchin

Scientific name: Psammechinus miliaris
Size: Average adult is 5cm across
Colour: Green
Habitat: Rocky shores, mainly in crevices
Facts:

They eat mostly seaweed they scrape off the rock, but also eat small animals attached to the rock.
They have sharp spines, so be careful when handling them.
They use lots of small tube feet to move around at high tide.
Pieces of seaweed and shell are trapped among the spines as camouflage.
