Pencil Urchin - by Quill

We found the spines of a red pencil urchin also known as the Heterocentrotus mamillatus. Anyways, I wanted to do some research about it. My mom also helped me draw a picture of the sea urchin.   

Heterocentrotus mamillatus are found throughout the tropical waters of the Indo- pacific region but especially Hawaii.

Its predators are fish and sometimes humans. (gross who would do that?!)

Its spines are thick and rouned allowing it to bore hard into things. It also helps to defend against predators, wave drag, and pressure.
