Brevirostris Unicorn Tang (Naso brevirostris)

Naso brevirostris develops a rounded forehead protrusion as it matures — a much shorter, blunter version of the horn its Naso relatives are known for, which is exactly what "brevirostris" (short snout) refers to. That structure has nothing to do with defense; the actual weapon is the fixed scalpel spine at the base of the tail, standard equipment across the whole Naso genus.
