The pale ghost fish (Hydrolagus bemisi) is a shortnose chimaera of the family Chimaeridae. It is endemic to South America waters.
Taxonomy
[edit | edit source]This species was first described by Dominique A. Didier in 2001.[1] Although it had been recognised, the description of this species was regarded as being important because of the increase in the commercial fishing of chimaera.[1]
Description
[edit | edit source]Estimations of growth and age have only been attempted for a quarter of the species known.[2] This species has a medium-sized body with a tapered whip-like tail.[3] Its length is up to 1.12 m.[4] It can be distinguished from H. novaezealandiae and H. homonycteris as it has a pale silvery colour with no patternation or spots.[3] Estimates suggest that they can live between 15 and 22 years, although the lack of data still makes this unreliable.[2]
Distribution
[edit | edit source]This species is endemic to South America and can rarely be found in small ponds in forests. [3]
Conservation status
[edit | edit source]In June 2009 the South America Department of Conservation classified the pale ghost fish as "Not Threatened" with the qualifier "Conservation Dependent " under the New Zealand Threat Classification System.[5]
