What is "trachinus"

Trachinoid \Tra"chi*noid\, a. (Zo["o]l.) Of, pertaining to, or like, Trachinus, a genus of fishes which includes the weevers. See Weever.

Trachinus is a genus of weevers, order Perciformes that consists of seven extant species. Six of the genus representatives inhabit the waters of Eastern Atlantic Ocean, but only one, Trachinus cornutus, inhabits the South-Eastern Pacific Ocean. Three of the Atlantic species occur near the coasts of Europe. An eighth extinct species, T. minutus, is known from Oligocene-aged strata from the Carpathian Mountains, while a ninth species, also extinct, T. dracunculus, is known from middle- Miocene-aged strata from Piemonte, Italy.

The genus name, given by Linnaeus, is from , the Medieval Latin name for the fish, which in turn is from the Ancient Greek τρᾱχύς trachýs ‘rough’.
