Bareskin Dogfish: I have an affinity with this dogfish. Little is known about how it works or the environment it inhabits. It is actually a shark and has so far only been found near Japan, along the Australian coast from about Brisbane to Hobart and in a relatively small area from Perth to the north.

Apparently they are dark in color with white-tipped fins, which suggest the pictured specimen above is either an albino or just a very crook sample.

According to what I could find out about them they have no anal fin (who would want one) and has grooved dorsal spines with the second larger than the first. It has a blunt nose, large eyes and large nostrils. It grows to a a maximum of  about 45cm.

They are found in a depth range of 500m to 1200m.

It has litters of three to 22 pups.

And that is about where the information on this thing ends: No information on the reproductive cycle, no information on annual fecundity, gestation period, age at maturity or longevity.
