Heterocentrotus trigonarius,[1] commonly known as the slate pencil urchin or red slate pencil urchin,[2] is found in the tropical waters of the Indo-Pacific region.[1] Heterocentrotus mamillatus is a similar, related species.[2]
Heterocentrotus trigonarius can grow to 30 cm (12 in) in diameter (spine-to-spine). The spines are potentially harmful to humans if trodden on.[2]
