Perfect for ocean school plays, rock pool habitat classroom projects, World Book Day, birthday parties, and prickly imaginative underwater adventures.

The sea urchin is a brilliant rock pooling discovery that children love to find and examine - and the biology behind those spines, that strange mouth and those water-powered tube feet is genuinely extraordinary.

5 Interesting Facts About Sea Urchins!

Sea urchins move using hundreds of tiny tube feet - these water-filled hydraulic appendages extend and contract to grip surfaces and pull the animal along, controlled by an internal water vascular system.
Their mouth is on their underside and contains five teeth arranged in a structure called Aristotle's Lantern - a complex, self-sharpening apparatus used to scrape algae off rocks.
Sea urchins are related to starfish, sand dollars and sea cucumbers - all members of the phylum Echinodermata, meaning 'spiny skin', which share a unique radial five-fold body symmetry.
Some sea urchins use tools - they pick up shells, pebbles and pieces of seaweed and hold them over their body as a sunshade and camouflage, gripping them with their tube feet.
Sea urchin roe (called uni in Japanese cuisine) is considered a delicacy - the bright orange or yellow reproductive organs are eaten raw in sushi and are prized for their rich, briny flavour.
