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); torrei: In honor of Cuban zoologist Carlos de la Torre (1858-1950), who recognized this species as new and granted Howell Rivero permission to study and describe it. (See ETYFish).
