It is for the first time described in 2007 in the scientific journal " Zootaxa " [1] . The holotype is an adult female 71 cm long, caught off the coast of Queensland, Australia, in 1985 [2] .
This species lives in the western Pacific Ocean off the coast of Queensland at a depth of 590-606 m [1] .
Parmaturus bigus has a soft body with velvety skin covered with a placoidal scale with three teeth. The color is even yellow-brown. The edges of the fins are slightly paler than the main color. The caudal margins of the dorsal, caudal, and anal fins have a white border. The dorsal caudal crest is well developed, the ventral caudal crest distinct, but not high. The ridges are covered with enlarged scales. The teeth also have an elongated central tooth and two small lateral tips. There are 120 dentitions on the upper jaw. The first dorsal fin is slightly shifted back relative to the middle of the body. The distance from the tip of the muzzle to the base of the first dorsal fin is 54.9% of the body length. The ventral fins are located in front of the middle of the body. The distance from the tip of the muzzle to the base of the pectoral fins is 48.9% of the body length. The muzzle is relatively short, the length of the mouth is 3.6% of the body length. At the corners of the mouth there are short labial furrows. The head is short. The second dorsal fin is larger than the first. A total of 144 vertebrae [1] .
There is no danger to humans. It has no commercial value. There is insufficient data to determine the conservation status of the species [3] .
