Shark

Sharks are enemies found in the first and second Turtle Zone levels in Super Mario Land 2: 6 Golden Coins. Normally, they swim slowly, but when Mario gets close to them, they start swimming faster, charging at him. Since they are underwater enemies, Mario cannot stomp on them, and unlike many other enemies fireballs do not affect them. The only way to defeat them is with a Star, or, in rare cases, a Green Shell from the surface. They wear boxing gloves, but they don't seem to use them against Mario.

In volume 9 of the Super Mario-kun, Mario, Luigi, and Yoshi encounter a shark during their boat trip. The shark attacks them, but Mario throws Yoshi to the shark to defeat it, although Yoshi gets injured.

Fire is ineffective, so you will have a hard time in the water. It moves only horizontally, so you will have to change your position.''
