Where do they live
Map Of The Blackfin Gulper Shark’s Habitat
The rarity of the species has made it difficult to determine its exact range, with sightings in the west Pacific and Indian Oceans.
These sharks live on the continental shelves, at depths ranging from 1427 to 2526 ft. They seem to have a preference for tropical waters.
While the exact diet remains unknown, an examination of the stomach contents of captured specimens reveals that cephalopods and fishes seem to be commonly consumed.
Blackfin gulper sharks are viviparous, giving live birth to a litter of 2 pups. At birth, these sharks are 12.2-13.7 inches long.
Interactions with humans
There is little data about this shark, but the IUCN classified it as “Endangered” or “EN” due to heavy fishing pressure in its potential range.
