Rat

Tactics
The easiest enemy in the game mostly hanging around on the ground or swimming in the water. Just shoot with your pistols, and jump backwards when they get to close or you're on dry ground while they're floating on the water. They bite Lara and cause little damage but can cause her health bar to drop while continuosly biting her.
