Males and females: females are generally larger than males. Males have external reproductive organs

Very deep water minimum (1300 meters)

Have to be in dark water which is typically at the bottom of the ocean

They live near isopods, dragonfish, cephalopods, decopods, and crustaceans

Very barren terrain because of how deep they are

Pacific, Atlantic, and Indian ocean 

Not invasive anywhere due to the very particular climate they have to live in

It eats  isopods, dragonfish, cephalopods, decopods, and crustaceans

It eats a few hundred to 1000 calories per day but since little information is known about them its hard to know

Its an active predator so it will seek out its food but most of the time its pretty lazy

It lives alone and is rarley seen in groups 

since they live alone there is no community structure and the depth they live is very deep so its hard to research

Their interactions with other goblin sharks are limited to mating seasons.
