What Is a Spotted Eagle Ray Barb
The spotted eagle ray barb is a sharp, venomous spine on the tail of the spotted eagle ray. It is made of hardened cartilage and covered with a thin epithelial sheath that can break off in a wound.
Anatomy and Function
Typically one or two barbs are located near the base of the tail. They are used for defense against predators. The spine has backward-facing barbs that make removal difficult and can cause painful injuries.
Safety and Handling
In the wild, barbs are normally flat against the tail and only deployed when the ray feels threatened. Divers should avoid touching or stepping on spotted eagle rays. Injuries require medical attention because the venom can cause swelling, pain, and infection.
