SizeLarger animals tend to be more intimidating because of their sheer mass and strength. The size of an animal can also be an indicator of the potential damage it can cause.
-
Bite strengthAnimals with a strong bite force, such as sharks, can cause significant damage to their prey or a potential threat with a single bite. This factor is especially important for carnivorous marine animals that are predatory.

-
Camouflage and stalking abilitiesThe ability of an animal to blend in with its surroundings or stalk its prey stealthily can make it particularly frightening as potential victims may not see it coming.
-
Rarity/unknown behaviorsSome deep-sea creatures or rarely encountered marine animals may instill fear due to their unfamiliarity and our lack of understanding about their behavior and potential threat level.
