The species was first described in a special bulletin of the US National Museum in 1896 [3] . The holotype is an immature male 15 cm long, caught in off the coast of Barbados at a depth of 366 m [4] . The species epithet is probably given due to the similarity of the spotted coloration with the coloration of an ordinary boa constrictor [5] .
Endemic to the Caribbean . It lives on the island slope off the coast of Barbados, the Lesser Antilles , Haiti , the Dominican Republic and Jamaica , as well as on the mainland slope off the coast of Honduras , Costa Rica , Panama and Colombia at a depth of 329–676 m [6] .
The Caribbean cat shark has a rather thin body. The width of the head is 2/3 of its length. The nostrils are covered with wide valves, which are separated by a narrow gap. The second dorsal fin is smaller than the first. The base of the first dorsal fin is located behind the base of the ventral fins, and the base of the second dorsal fin is above the middle of the base of the anal fin. The inter-dorsal distance is greater than the base length of the anal fin. Rough skin is covered with small placoid scales . Numerous dark spots are scattered along the back and sides, forming the dashed contours of saddle marks [7] .
Probably, this species reproduces by laying eggs [7] .
This species is not dangerous to humans. It has no commercial value. Deep-sea fishing in habitats is currently absent. The International Union for Conservation of Nature has rated the conservation status of this species as “Least Concerns” [2] .
