Fittingly for Halloween: the goblin shark. It looks really scary on most pictures after being caught. Simply swimming, the goblin shark looks rather normal.

The goblin shark has a slender but flabby body, its color changes with age from light grey to pink due to visible blood vessels beneath the soft skin. Its long snout contains numerous ampullae of Lorenzini (can detect the electric fields produced by other animals) – like the head of the hammerhead shark. Prey can be sucked in or caught with its abruptly protruding jaws. There are elastic ligaments pulled taut when holding the jaws back, therefore being able to catapult them forward (as demonstrated in the video).
Male goblin sharks mature at about 2.6 m (8.5 ft) long and are up to 4 m (13 ft) long. A female has been captured at 5.4–6.2 m (18–20 ft) long.

Goblin sharks live worldwide at depths of 40 to 1300 m (130 to 4,300 ft) and are specialized for deep-sea conditions. They are considered living fossils.
