Nature Stars: 40

What are nature stars?

About: A medium-sized sea-urchin, heart-shaped and up to 9cm long. Pale greyish-brown in colour, densely covered in fine, beige spines, looking hairy. Lives buried up to 15cm down in muddy and sandy sediments.

How to identify: Often washed up, when it tends to lose most of its spines. Recognisable by the heart shape, dull colour and thin, brittle shell.

Where: Found on sandy and muddy shores all round our coasts.

Fantastic fact: Named because, when washed up, they resemble a rather brittle potato.
