 Green Sea Urchin

Scientific name: Psammechinus miliaris

Colour: Green
Habitat: Rocky shores, mainly in crevices

  • 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.
