About the Achilles tang
A member of the surgeonfish family, this dark-colored tang is easily recognized by the brilliant orange patch at the base of their tail.
Did you know?
- The orange patch near the base of the Achilles tang conceals a “switch blade” used for self-defense. See the bump?
- During an attack, a tang slashes at enemy fish, which include predators or a rival tang.
An Achilles tang’s defensive spine contains venom, which means double trouble for predators.
