Torion

From the Super Mario Wiki

A Torion is a fast-moving, carnivorous fish in the game Super Mario Land. They are weak against the Marine Pop's torpedoes and are defeated after only one successful hit. However, they would only award Mario with a mere 100 points each. Torions are found only in World 2-3 of the Muda Kingdom, the Marine Pop's level. Torions always swim in groups of three. According to the instruction manual of Super Mario Land, Honens are undead Torions that were eaten by Tatanga. The actual appearance of a Torion is subject to debate, as one official artwork depicts the fish with a dorsal fin while another depicts a Torion without a dorsal fin.
