What research has been done?
Most of the published literature on prickly sharks has been about their distribution. The seminal paper on what is known about prickly shark range and depth distribution was published as Long 2011. We know prickly sharks live in submarine canyons, around sea mounts and over sandy habitat. My research on habitat use was published as Dawson and Starr 2009. Small sharks, egg cases of other sharks and rays, octopus, squid, chimera and other mid-water and benthic fishes have been found in prickly shark stomachs. We don't know how often they reproduce but we know the females need to grow to around 3 m or 10 ft to reproduce and pregnant females have been caught carrying up to 113 pups! Research on what prickly sharks eat and their size at reproductive maturity in Crow et al.1996.
