Sea Urchins (UNI)

These spiky, slow moving little sea creatures are common in salt water throughout the world. A The easiest way to describe one is as a “ball of spines,” though they have been called the “hedgehogs of the sea.” They look like a pincushion filled with needles and appear in a wide variety of colors, shapes, and sizes. There are thought to be more than 950 species, some with incredibly long, thin spines, while others have short thick nubs. Contrary to conventional wisdom, most sea urchins don’t sting people and aren’t poisonous or venomous. It can be painful, however, if a spine pokes through your skin.
