Grenadier

The Grenadier is as a common enemy in the Dark Depths' waters. They can appear as a small or large variant.

Description
Grenadiers are gadiform marine fish found at great depths from the Arctic to Antarctic. Typified by large heads with large mouths and eyes, grenadiers have slender bodies that taper greatly to very thin caudal peduncles or tails (excluding one species with no tail fin at all). The Grenadiers found in The Living Infinite, however, have grown to a very large size and are often seen with blood around their mouthes, giving them a very threatening appearance indicative to their behavior.

Behavior
The Grenadiers will chase the submarine and bite it if close enough. They will usually overshot the submarine due to their high velocity, but as they can appear in large numbers, they can be very dangerous if not quickly killed, a problem aggravated by the fact they can be relatively very small, making them difficult to hit.
