Oceanography

Heart urchin

Heart-shaped irregular sea urchin with a distinct bilateral heart-like to slightly oval outline rather than a perfect sphere. The body is low-domed to slightly flattened, with a domed top and flattened underside, often showing a subtle front indentation and slight asymmetry associated with a burrowing form. The surface is covered in very short, dense, fine velvety spines. Coloration ranges from pale beige, cream, and tan to light brown, muted purple-brown, dusty purple, or purple-gray.
