Special Abilities
Keen Scent (Ex) A shark can notice creatures by scent in a 180-foot radius underwater and can detect blood in the water at ranges of up to a mile.

The shark is a relentless eating machine, a creature evolved over the course of eons to do one job perfectly—hunting. Sharks have achieved a special place in the lore of most seafaring races, who view them as devils, monsters, and the wrath of the gods.

The shark presented here is a 10-foot-long, 300-pound blue shark. Smaller sharks exist, although these are not dangerous. The same cannot be said of larger sharks, such as the following (you can create stats for these sharks by applying the indicated simple templates).
