Arapaima

The Arapaima is a Hardmode enemy that spawns in water pools within the Jungle and Underground Jungle biomes. They swim much faster than most fish. Although dealing high damage, this enemy has very low knockback resistance, so high knockback weapons are useful.

The Arapaima can jump from the water, and therefore is able to attack players on land close to the water.
