 * Year Assessed:

Justification:** A rare deepwater dogfish with a widespread global distribution, inhabiting the upper continental slopes and outer continental shelf area. Believed to have the lowest reproductive potential of all elasmobranch species; its reproductive biology is characterized by a late onset of maturity (12 to 16 years in females), only one pup per litter and a two-year gestation period with occasional resting periods. This makes it extremely vulnerable to overexploitation and population depletion. Despite a lack of data for certain regions within its geographic range, this species is globally assessed as Vulnerable on the basis of its limiting life history traits and the global increase in unmanaged fishing effort to exploit deeper waters.

**Population Count:** unknown Decreasing  **↓ **



**Reproduction:** Aplacental viviparous (ovoviviparous). 1 to 6 pups per litter. Size at birth about 35 cm. Males reach sexual maturity between 70 cm and 130 cm, females between 90 cm and 145 cm.

**Threats:**
 * This is a widespread species that is reported to be heavily fished and caught as bycatch in the Northeast Atlantic, the Northwest Pacific and other regions. As the global fishing fleet tends towards deeper and deeper unexploited fishing grounds, the threat from incidental catch to this species grows.
 * Conservation Efforts:**
 * A quota has been in place for years with these sharks, the quota is not an exact number, they watch how much of the population decreases before they official stop the killing of these sharks.


 * Solutions:**


 * Find ways to stop the bycatch of Gulper Sharks
 * Limit fishing in living zones, because of the long maturation period
 * Enforce laws that force fisherman to return Gulper Sharks back to the Ocean after they are caught.


 * Scavenger Hunt:

1) What color are Gulper Shark's eyes?

2) Up to how many pups can a pregnant Gulper Shark produce?

3) What eats Gulper Sharks? **
