Razor Fin (Ex)

A bladefish has quick reflexes and powerful muscles along its length. It can attack underwater as though it had the Spring Attack feat. It can also make a full attack while using the feat as long as one attack is with each of its natural weapons.


Environment any ocean
Organization family (3–6), school (7–12), or storm (12–50)

Fast and strong, bladefish swim across oceans in instinctive circuits that cover thousands of miles. These circuits take them through their entire life cycle, including live birth, adolescence, hunting, and mating, Though beautiful to behold, bladefish are deadly carnivores and deliver brutal blows very rapidly as they charge in, swim past, and charge in again. Their skulls narrow to a flat, horizontal blade and their tail fins sport a similar vertical protrusion. Both bear shining scales along these sharp edges as decoration. A long, sharp mouth blade is ideal for hunting and defense, while the brightest sheen along its blades attracts the most desirable mates.

The greatest weapon bladefish have is in their numbers. Vast storms of them swim their lifelong circuits from the water’s surface down to 200 feet deep. When one senses an intruder, it determines whether the threat is manageable or overwhelming and reacts by charging or fleeing, respectively.

The entire community of bladefish joins in that reaction, swimming away as one or attacking in a rapid frenzy of sharp bills. Weaker bladefish are left behind or join the fight late and risk losing their meal to more aggressive members.

An adult bladefish is 7 feet long and weighs 600 pounds. Larger, rarer species can reach 40 feet in length and live for over a hundred years.
