Biterfish

A school of biterfish.

Biterfish are small fish creatures that live in the waters of Na Pali. These creatures bear the appearance of a normal fish, as those seen on Earth. Biterfish are capable of biting, and can't generally be killed with a hitscan weapon. Using weapons which do splash damage, such as a Rocket Launcher or a Flak Cannon, will let you achieve the best results against these creatures. Most of them are not aggressive, but those who are will drain one hitpoint per bite. Knowing that the biterfish usually come in schools, they can be quite a threat as they are extremely hard to aim at; thus it is intelligent to ignore and swim around these schools, and hope none get too close to you.
