African Dwarf Sawshark (image) California Academy of Sciences Caption Pristiophorus nancyae, or the African dwarf sawshark, is one of 140 new species described by the California Academy of Sciences in 2011. This specimen was collected at a depth of 1,600 feet off the coast of Mozambique. It is notable for its elongated blade-like snout, or "rostrum," which is studded with sharp teeth and used as a weapon. The sawshark will swim through a school of fish swinging its rostrum back and forth, stunning and injuring prey, and then swim back to consume the casualties.
