To which family, referencing sharp caudal spines, does Zebrasoma flavescens belong?

Answer

Acanthuridae

The Yellow Tang is classified within the Family Acanthuridae. This family name itself is derived from or directly references one of the most recognized and distinctive morphological features shared by all its members: the presence of sharp, scalpel-like spines situated near the base of the tail fin. These defensive or territorial structures are so prominent that they give the entire family the common name 'surgeonfish.' When handling these fish, aquarists must exercise caution specifically because of these caudal spines, which can inflict injury. This family placement groups the Yellow Tang with its closest evolutionary relatives who share this unique anatomical trait.
