sea animals that are related to sand dollars and starfish. They can easily be mistaken for shells or rocks because of their hard, round, spiny bodies.
Sea urchins are primitive animals, but they boast a powerful defense mechanism. Their stings can be extremely painful and may cause extensive damage to the skin, tissue, and even bone.
The calcium-filled spines that a sting can leave behind can be difficult to remove from the skin. Prompt extraction of them, however, can prevent further injury.
Fast facts on sea urchin stings:
Most sea urchin stings are a painful annoyance only.
The spines hurt when they enter the skin, as a large splinter would.
Anyone with a history of allergic reactions to stings or bites should get medical help after a sea urchin sting.
The only way to completely avoid a sea urchin sting is to stay out of the ocean.
