Sawshark
The shortnose sawshark ("Pristiophorus nudipinnis") is similar to the longnose sawshark; however, it has a slightly compressed body and shorter more narrow rostrum. It has 13 teeth in front of its barbels and 6 behind. The shortnose sawshark tends to be uniformly slate grey with no markings on its dorsal side and pale white or cream on its ventral side. Females reach around 124 cm (49 in) long, and males reach around 110 cm (43 in) long. These sharks can live to be up to 9 years old. Like other sawsharks, the Short Nose lives a benthic lifestyle and feeds on benthic invertebrates. It uses its barbels to detect life on the ocean floor which it then paralyzes with its rostrum. The species is ovoviviparous and tends to give birth to a litter of 7–14 pups biannually. It inhabits ocean floors off the coast of Australia.
