What is "terapon"

Terapon is a genus of fish in the Terapontidae family.

Its deprecated junior homonym is Therapon. It was introduced since "Terapon" was perceived as an incorrect rendering of the Greek word therapon. In fact, the intended etymology was = "strange thing, monster, wonder" (cf. teratosaurus) + Greek: pontios = "marine", pertaining to the sea.
