Blogg

A Blogg is a species found in the GameCube game Metroid Prime 2: Echoes. They are large, violent sea creatures who'll ram into anything that attacks them - or anything that they spot. They only have one weak spot - which is in their mouths. They'll only reveal their mouths right before they charge into you, suggesting that they more than likely plan to eat anyone they attack.

Their young, Blogglings, are not nearly as powerful, and often times must rely on their parents for protection, while otherwise they're nearly defenseless.
