Ynghylch

Also known as the common sea urchin, the edible sea urchin is large and round with short, strong spines. It is often a pinkish-purple colour but it can be red, green or yellow. It lives on the seabed down to depths of 40m and can occasionally be found in rockpools on a very low tide. The edible sea urchin is a grazer, feasting on seaweeds, bryozoans, barnacles and anything else it can find. Sea urchins are echinoderms, related to starfish, sea cucumbers and brittlestars. Their scientific name "Echinus" comes from the Greek word for hedgehog - it's easy to see why with all those spines!

Avoid buying any curios, gifts or ornaments that feature dried sea creatures, especially threatened species such as sea urchins, seahorses or coral. If you find an empty sea urchin test (shell) on the beach, then that's okay to keep!
