Various sea urchins are spiny sea creatures of the class Echinoidea found in oceans all over the world.

The sea urcin we have are called, Echinothrix calamaris, known commonly as the banded sea urchin or double spined urchin among other vernacular names, is a species of sea urchin in the family Diadematidae.


According to Wiki, "The Banded sea urchin is widespread throughout the tropical waters of the Indo-Pacific region, from eastern coast of Africa to French Polynesia, including Hawaii and the Red Sea.

It occurs from the surface to 70 metres (230 ft) depth and can be found in lagoons, external reef slopes and channels.

This sea urchin is active at night, hiding in crevices or under rocks during the day.

The thinner spines are venomous, but not dangerous."


(The name comes from their resemblance to hedgehogs, hedgehog being one meaning of the word "urchin"). Their shell, which biologists call the test, is globular in shape, and covered with spines.

 Echinoids have a rich fossil record dating back to the Ordovician, some 450 million years ago.
