General Attributes

The sea-urchin's (echinus) shell is sharp with spines like a chestnut when it falls from the tree still covered. The name is taken from the hedgehog, also called echinus, which also has spines on its back.


The sea urchin is not a fish; it is a marine invertebrate. In modern taxonomy, some European urchins are in the Echinus genus in the Echinidae family.
