The goblin shark uses special sensing organs called the Ampullae of Lorenzini that are located on their snout. With this, they are able to electronically detect the prey. Their jaws are conditioned for a rapid projection and thus this is how they capture their prey.
The strong ligaments of the mandibular joints keep them tight while swimming. When they find a prey, the jaw projects forward in the form of a catapult.
The shape of their thin and narrow teeth are shaped like a hole punch, and their posterior teeth are desgined for grinding. This suggests that they feed mainly on soft prey: small fish, octopus, squid, and shrimp.
