Monster Manual (3E)
Sea lions attack on sight, either for food or to defend their territory, and use both claws and teeth to grab and rend their prey. They display tremendous courage, always fighting to the death, even against creatures many times their size. Pairs and prides of sea lions attack in concert, trying to wear rite opponent down until one beast can dispatch it.
Rend (Ex): A sea lion that hits with both claw attacks latches onto the opponent's body and tears the flesh. This automatically deals an additional 2d6+6 points of damage.
