The Australian ghostshark was proposed as a model cartilaginous fish genome because of its relatively small genome size. Its genome is estimated to be 910 megabases long, which is the smallest among all the cartilaginous fishes and one-third the size of the human genome (3000 Mb).
Several near-shore species are purposefully caught for their meat, especially callorhinchids, Hydrolagus bemisi (pale ghost shark), and Hydrolagus novaezealandiae (dark ghost shark). Modern quotas have helped to moderate collection of these species to a sustainable level, though Callorhinchus milii (the Australian ghostshark ) experienced ...
Sewage treatment plants mix these organisms as activated sludge or circulate water past organisms living on trickling filters or rotating biological contactors. [5] Aquatic vegetation may provide similar surface habitat for purifying bacteria, protozoa, and rotifers in a pond or marsh setting; although water circulation is often less effective.

The most common location of export is Australia. Under the IUCN, two of the three extant species of Callorhinchidae are listed as least concern, as they remain common. Callorhinchus callorynchus is listed as Vulnerable. [10] While fishing quotas are in place in Australia and New Zealand, this is the furthest that the conservation effort spans.
Scientists in New Zealand have discovered a new species of long-nosed "ghost shark" that thrives in the deep waters of the Pacific Ocean.. The Australasian Narrow-nosed Spookfish was found living ...
