1 Killer Whale The Orca, or Killer Whale (Orcinus orca), is a toothed whale belonging to the oceanic dolphin family, of which it is the largest member. It is recognizable by its black-and-white patterned body. Orcas are a cosmopolitan species and can be found in all of the world's oceans, in a variety of marine environments,... read more

The crowned king of the seas. Although these creatures aren't as fantastical or nightmare-inspiring as the other predators on this list, Killer Whales are fast, smart and deadly.

2 Great White Shark The great white shark (Carcharodon carcharias), also known as the white shark, white pointer, or simply great white, is a species of large mackerel shark which can be found in the coastal surface waters of all the major oceans. It is notable for its size, with larger female individuals growing to 6.1 m (20 ft) in length and 1,905–2,268 kg (4,200–5,000 lb) in weight at maturity. However, most are smaller; males measure 3.4 to 4.0 m (11 to 13 ft), and females measure 4.6 to 4.9 m (15 to 16 ft) on average. According to a 2014 study, the lifespan of great white sharks is estimated to be as long as 70 years or more, well above previous estimates, making it one of the longest lived cartilaginous ...read more.

The scariest animal on the planet. The Great White Shark is the largest species of shark alive today and grows up to give meters in length. The true stuff of horror movies.

3 Giant Squid The giant squid is a deep-ocean dwelling squid in the family Architeuthidae. Giant squid can grow to a tremendous size due to deep-sea gigantism: recent estimates put the maximum size at 13 m for females and 10 m for males from the posterior fins to the tip of the two long tentacles (second only to the colossal squid at an estimated 14 m.)

A colossal, alien monster. The Giant Squid, armed with scary suckers, tremendous tentacles and a brutal beak, the giant squid rules over its deep-sea kingdom with an iron grip.

4 Sperm Whale

The biggest 'true' predator on earth. Massive enough to engage in blood-thirsty battles with the Giant Squid, the Sperm Whale employs its lower jaw lined with steak-knife teeth as it's deadliest weapon.

5 Saltwater Crocodile The saltwater crocodile, also known as the estuarine crocodile, Indo-Pacific crocodile, marine crocodile, sea crocodile or informally as saltie, is the largest of all living reptiles, as well as the largest riparian predator in the world.

Let's just say it has the strongest bite force. Put this thing in first

6 Colossal Squid

Even more staggering in size than its cousin, the Giant Squid, the Colossal Squid can grow up to 15 meters. Lethal hooks attached to its tentacles helps it catch and drag in prey. Not much is known about this mysterious monster as a specimen has not been seen alive.

7 Bull Shark The bull shark is a requiem shark that is considerably dangerous. These sharks live in both freshwater and saltwater environments. Bull sharks can be recognized by seeing a shark in freshwater and watching the shark due a hit and run.
8 Tiger Shark The tiger shark is a species of requiem shark and the only extant member of the genus Galeocerdo. It is a large macropredator, capable of attaining a length over 5 m. Populations are found in many tropical and temperate waters, especially around central Pacific islands.
9 Ragged-tooth Shark
10 Blue Ringed Octopus The Blue Ringed Octopuses (Hapalochlaena) are the four strongly venomous species that are found on the coral reefs and tidal pools in the Pacific and Indian Ocean, particularly from Australia to Japan. It is known as one of the most poisonous and deadliest sea creatures. It can kill a human body by injecting a toxin from its saliva by biting a victim.

Looks wicked cool and is a true bad ass

The Contenders

16 Lionfish
17 Shortfin Mako
18 Humboldt Squid

You have more chance of survival in the water with a Great White Shark. This underestimated squids are more aggressive than any other animal on this list. They drag fisherman off boats (like their mythical cousin the Kraken), attack divers without reason and they can ambush you from the deep. And before you know what's happening, it's already happened...

19 Banded Sea Krait

One of the most toxic snakes on earth. One bite and you could be dead.

20 Barracuda
21 Thresher Shark

At first glance you think "Oh, it doesn't look too scary, it just catches fish with its jaws" but it is one true badass. It's fast and can leap 9 feet out of the water. Their deadliest weapon is the most surprising one: their tail. They whip fish and squid with their tail, stunning, or even killing their prey. They even create shockwaves by whipping their tail in the water without even touching the fish.
