While aquariums screensavers are wonderful fun and include a wide variety of fish from both fresh and salt water, there are some creatures found in the ocean you would not want to appear in your virtual tank. Some sea creatures are too terrifying to appear on screen in a calming aquarium screensaver; here we provide a list of the Top Ten scariest forms of sea life.

 10. Phromima: Found in the deep sea, this creature has become completely invisible as a defense mechanism. While this particular form of sea life is of no immediate threat to the human race, the scary looking figure of the Phronima was one of the main sources of inspiration for the Alien series.

The average size of a Phronima is about .98 inches. They are carnivorous and feed on plankton and often use jellyfish shells as their house.

 9. Moray eel: Once portrayed in the Disney movie,  The Little Mermaid,  moray eels slither through the waters stealthy, waiting to strike. Moray eels have been known to grow up to 13 feet in length and can weigh up to 79 pounds.

The moray eel consists of only one fin along its back called the dorsal fin. They have small eyes, relying mostly on their sense of smell to catch their unsuspecting prey. The large teeth of the Moray allow it to tear at the flesh of its victims instead of catching it and holding it.

While Moray eels are not known to be particularly vicious to humans, they are vicious to other sea creatures and have at times mistaken human fingers as potential prey.

  8. Piranha: A piranha is a carnivorous freshwater fish found mainly in South American waters. They are an extremely aggressive fish with sharp teeth that can pierce flesh. Humans bathing and swimming in piranha infested waters often find themselves being bitten if they are not careful.

They are a constant nuisance to fishers as a piranha will often steal bate and mutilate other fish caught on the line. When in tanks piranhas have extremely aggressive tendencies, preying on the weak of the group and when not fed well enough, reverting to cannibalism.

An account of the piranha given by former President Theodore Roosevelt describes the piranha as the most ferocious fish in the world. Excited by blood in water the piranha will devour any wounded beast or man.

  7. Giant Squid: Once believed to be nothing more than a monster in a story, recent discoveries have proved that this massive ocean terror does exist. Dwelling in the deep ocean, the giant squid can grow up to sizes of 43 feet and is estimated as one of the world s largest living creatures.

The giant squid has eight arms and two ling tentacles, each with the ability to reach at great lengths, adding to this predator s arsenal. On each arm and tentacle are hundreds of suction cups lined with sharp rings of chitin. These are used to hold the squid s prey in place as it devours it.

While no known fatal attacks on humans have been historically noted, there is a first time for everything 

  6. Great White Shark: From the Hollywood hit  Jaws  to uncounted attacks in the seas, white sharks have been a terror of swimmers throughout the ages. Found on all costal surfaces of the oceans this shark can grow to lengths of up to 20 feet.

Investigation into the great white shark by modern scientists have somewhat proven that while sharks do attack humans, most attacks are not fatal. The most popular reason for this is that humans are unpalatable to sharks, as usually they are too lanky and don t have enough meat. A shark can tell with one bite whether or not specific prey is worth pursuing. While a shark may not eat you, he will still take a bite, and for this reason the great white shark stays a terror of the seas.

  5. Black Dragonfish: This species of fish is long and slender and is another of the terrors to be found in the deep sea. Found at depths of 2000 meters, the Black Dragon Fish, like many other deep sea predators, uses photophores along its body to attract its prey and avoid predators.

The pigmentation of the Black Dragonfish is unique in that it has such long wavelengths it is almost infrared, which make it almost impossible for the human eye to see.

4. Fangtooth: Found in the deep areas of the ocean, the Fangtooth is a very ferocious looking fish. It has the largest set of teeth in the ocean, relative to body size. The Fangtooth s teeth are in fact, so large that it is impossible for it to close its mouth.

The Fangtooth is one of the deepest known fish, found at times a far as 16,400 feet down. They catch their prey by swift movement and by piercing it with their needle-sharp teeth.

    3. Viperfish: The Viperfish is one of the sea s most fierce predators with long teeth and flashing lights on its spine to lure its victims. The fangs of the Viperfish are so long that they don t fit in the mouth of the fish, but rather curve up almost to the eyes of the terrifying fish.

The viperfish can catch its prey in a number of deadly ways. One way is by swimming at its prey at swift speeds and injuring it with its massive teeth. The other is to hang motionless in the water, flashing its light producing organ called a photophore located on its long dorsal spine. This light attracts curious victims and draws them close where the Viperfish then strikes.

  2. Anglerfish: Found deep in the ocean, where not a speck of light can reach, the angler fish can be found luring its prey with bioluminescence. The light is created by bacteria permanently living inside the lure of the fish. The light flashes in the darkness, intriguing surrounding sea creatures and drawing them to their doom.

Female Angler Fish are the only ones with the light as males are only one-tenth the size of the females and don t have colossal teeth.

A famous appearance of the angler fish can be seen in the Disney movie  Finding Nemo,  where two of the main characters are drawn into the deep ocean and come face to face with this monstrous creature.

Generally, Angler Fish are of no threat to humans or vice versa, because of their deep location. However, they have been known to surface occasionally during El Nino.

  1. The Megalodon Shark: The Megladon is a prehistoric shark of the same category as the white shark. The jaws of the Megladon are generally measured at about 6 feet in height, with teeth that measure 7 inches. From this fact it is estimated that the Megladon shark measured near 60 feet in length!

It is suggested that the prey of the Megladon usually consisted of large animals, such as whales. At any given time a Megladon shark would have up to 276 teeth in its massive mouth with the biting force of 182,000 newtons (ten times that of a great white shark).

The Megladon is supposedly extinct, but the question has been raised a few times as to whether that fact is truly accurate. The ocean is a very large place and has many depths that have not yet been explored. Keep that in mind next time you go swimming.
