The African dwarf sawshark (Pristiophorus nancyae) was accidentally captured in a 1,600-foot-deep (490-meter-deep) trawl off Mozambique. The animal is only the seventh species of sawshark known to science, according to David Ebert, a research associate at the Academy.

The predator has a long, tooth-studded snout that it uses like a sword, whipping the appendage through schools of fish and then returning to eat any casualties.

Along with the sawshark, a new species of angel shark, Squatina caillieti, was named from a single specimen collected in 1,200-foot-deep (370-meter-deep) water off the Philippine island of Luzon, Ebert said.

Bottom-dwelling angel sharks, whose large pectoral fins resemble wings, lie partially buried in sediment
