Sea urchins or urchins are small, spiny, globular animals.
Humans harvest the urchin & serve its roe as a delicacy.
They inhabit all oceans. Their shell is round and spiny. Common colors include black and dull shades of green, olive, brown, purple, and red.
They move slowly, feeding mostly on algae. They have hundreds of tiny, transparent, adhesive "tube feet".
These are sea urchin shells or "tests". Each white band is a location of a row of "tube feet".
This is a sputnik sea urchin shell.
The name urchin is an old name for the round spiny hedgehogs that sea urchins resemble.
