Final Fantasy/Enemies/Shark

The Shark is a large fish with deadly jaws. Sharks inhabit the oceans of the world and often attack passing ships, attempting to make a meal of the crew and passengers. They are extremely tough and, unlike most fish, not generally used for human consumption. Rumors abound of unnatural experiments that crossed Sharks with men or elves to create the brutal Sahagin. The truth or falsehood of these rumors is impossible to ascertain, as the origins of the Sahagin are hidden by the depths.

Sharks, like all aquatic creatures, have an immunity to Quake and a resistance to  Fire but a weakness to  Lightning.
