Carvanha

“CARVANHA’s strongly developed jaws and its sharply pointed fangs pack the destructive power to rip out boat hulls. Many boats have been attacked and sunk by this POKéMON.”

— Pokémon Ruby

“If anything invades CARVANHA’s territory, it will swarm and tear at the intruder with its pointed fangs. On its own, however, this POKéMON turns suddenly timid.”

— Pokémon Sapphire

“CARVANHA attack ships in swarms, making them sink. Although it is said to be a very vicious POKéMON, it timidly flees as soon as it finds itself alone.”

— Pokémon Emerald
