The small-eyed rabbitfish (Hydrolagus affinis) is a species of fish in the Chimaeridae family. And within the last 15 years, another species was recognized as distinct from them: introducing Hydrolagus pallidus. Commonly known as the "pale ghost shark" or the "pale chimaera," this large species (they can reach up to 137.6 cm for females and 136 cm for males) is rather similar to H. affinis... in fact, they even overlap in range!
They have a depth range of 1188 to 2075 metres deep, but they may go possibly deeper, down to 2500 metres. They are a uniform pale grey to white color, while juveniles tend to be a darker grey-brown colour. Pale chimaeras have a large body, are stout, and have small eyes that are oval-shaped. Their skin is not deciduous, and typically remains intact when caught. They have short, pectoral fins that are broadly triangular. and their first dorsal fin high and triangular! #Finfact: Males have a robust frontal tenaculum that is bulbous with numerous sharp, curved hooks!
And that's all we know about these animals! The IUCN has assessed these animals as Least Concern (LC) by the IUCN.
