It seems Hydrolagus lemures and H. ogilbyi is now one species, Chimaera ogilbyi. See paper here.
TFUI is diving into the deep with the blackfin ghostshark (Hydrolagus lemures) this week! Also known as the Bight ghostshark, they are a slender, silver-coloured chimaera that sports a long snout, large pectoral fins, and a dorsal spine. No worries, that spine is shorter than the dorsal fin itself!
Blackfish ghostshark can get up to 58 cm in length, with males maturing at around 50 cm (female maturity size unknown). With a widespread distribution along the Australian continental slope (think Western Australia to Queensland and Tasmia), one would think scientists would have more information about these animals. However, it can be hard to get data on animals that live on or near the ocean floor bottom around 200 – 700 m deep.
For that reason, their diet and reproduction is unknown and the IUCN has assessed them as Least Concern (LC) due to their depth range keeping them relatively safe (or so we guess…).
have you heard of this critter before?
