Etymology: Scyliorhinus: skylion, Greek for dogfish or small shark; rhinus, from rhine (Gr.), rasp, alluding to a shark’s jagged, rasp-like skin. (See ETYFish); cervigoni: In honor of Venezuelan ichthyologist Fernando Cervigón Marcos (1930-2017), who recognized this shark as a distinct species in 1960. (See ETYFish).
