The seabed can be a very scary place. In general scientists and divers have had the opportunity to photograph creatures of the deep with not much friendly faces. With this variety, it was not difficult to list twenty of the most exotic specimens of marine fauna.
20 - Fish-black devil
Hardly a child recognize the name Melanocetus johnsonii , but a copy of this species frightened thousands of them when pursued Nemo and Dory in the movie "Finding Nemo" hit with the children. Besides scary, this fish has an interesting hunting strategy: he lives in very deep areas of the sea where the light hardly penetrates, it uses a bioluminescent Appendix and in front of the teeth, which attracts prey and serves as a stick fish bright.
19 - Sea Slug
A show of lights and colors is provided by various species of sea slugs, also called nudibranchs, which together are the order Opistobranchia . You may think this is not really a scary animal, but several species of sea slug is carnivorous, have sharp claws and sharp teeth called rádulas. Some even exceed 30 centimeters long.
See more beautiful photos of nudibranchs on Flickr.
18 - "Viperfish" saber-toothed
A combination of penetrating gaze and long, sharp teeth of this fish is a natural threat.Several species of the genus Chauliodus inhabit tropical waters where prey long penetrate more easily into the flesh of the victims.
17 - Sea Urchin
Strongylocentrotus purpuratus is the scientific name of a skittish animal, round and full spiculated. The dozens of tips are specially designed to protect it from predators. And they can come in various colors: the main ones are black, brown, purple, red and olive green.
16 - Shark big mouth
He lives in deep waters and is one of the main predators of the abyssal zones of the oceans. In his mouth, whose length passes several centimeters of the line of each of the eyes, are on hand more than 50 rows of small, firm, pointed teeth, always ready to smash their prey.
15 - Sea Cucumber
Its appearance can not be there the most frightening. Nevertheless, the species of the class Holothurioidea can be a much greater danger than you think. When attacked or threatened by a predator, the sea cucumbers release a toxic substance (and lethal in some cases) call Holothurin, hence the name.
14 - holothurians
Within the class of sea cucumbers, in fact, there are some dogs that do not even look like cucumbers. Some species, however, are round and have spiky body along tentacles that resemble tree roots. Some individuals are rich in lush colors, which extols its exotic side.
13 - black fish-dragon
If you had been surprised by the black devil fish, which has a bright appendix in the middle of the face to attract their prey, the black dragon fish ( Bathophilus indicus ) goes even further. Along the belly, he has arranged luminous organs irregularly, shining in the dark waters it inhabits. He is able to change its parts as burning your drives, which creates false silhouettes and deceives its victims. As if that were not enough, your eyes are equipped with a kind of "flashlight" that helps to better locate victims.
12 - Miracéu
The Brazilian version of the name for these fish, belonging to the family Uranoscopidae , it's no wonder: the hunting strategy of these species is to bury in the sand and just get his face out, face up. The miracéus penetrate the soil in a way with which they can get out quickly, and spend long periods in ambush, waiting for prey to appear.
11 - Morea
In English, they are called Moray eel ("eel" is eel), an indication that are eels, but in Brazil the more than 200 species of the family Muraenidae are known to moray eels.Some, like the Gymnothorax bathyphilus have a really scary face: teeth that vary in size depending on the species and piercing eyes.
10 - Rolling Morea
Even within the same genus, species found that match your intimidating guy with an impressive play of light and color throughout the body. This is the case of Gymnothorax undulates , which features brown spots on a body of a green so intense it seems to shine.
9 - Horn of Cabrinha
The name given by the practical guide to marine fish seem innocent, but who see an example of the species Peristedion miniatum around are faced with a monster. His body is covered with several layers, like armor, and along the trunk are pointed spines that help to hunt their prey.
8 - Fish-ogre
The lists of champions among the most fish scary teeth can not leave out the cornuta Anoplogaster , whose fangs are like those of a vampire. In proportion to body rest, it is one of the teeth of the animal world. But the ogre fish actually is frightening only in a zoomed photo: Its length rarely goes beyond 16 cm.
7 - Emperor Shrimp
We have spoken on this list on the sea cucumbers, which unleash a powerful toxic substance when they are harassed by predators. But there is a kind, imperator Periclimenes , which can take benefits from the bodies of sea cucumbers. The emperor shrimp parasite is not only of sea cucumbers as other animals, such as the slug of the sea. It is identified by its legs from a strong shade of purple.
6 - Lula-vampire-from-hell
The scientific name starts already scaring the observer: vampire squid . In good Portuguese, the squid-vampire-of-hell was named that way because of the bright red and bright your skin, not to mention the bright eyes and the membranes sticking their tentacles to each other, making them look like bat wings.
5 - Tatuíra
Have you heard the tatuíra? This Brazilian name defines a set of giant crustaceans that look like a beetle expanded in a thousand times. Nevertheless, the animals of its kind Bathynomus inhabit seas to significant depths. The largest specimens ever attain more than 40 centimeters long, which requires two adult hands to hold them.
4 - Fish-coffin
The format of this fish is among the most seabed unusual: it is an almost square body, above which stands a wide mouth and dark eyes. Nevertheless, giving the particularity Chaunax endeavouri is a small pair of legs below the trunk, which helps you get around.
3 - Jellyfish
Photographed in abyssal areas of the sea where the sun's rays can no longer spread, the species of jellyfish (genus Aequorea ) appear contoured made in a bright ghostly light that seems phosphorescent. The size of jellyfish can be a scary factor: some species even have tentacles 30 meters long.
2 - Medusa
Although Americans also call it jellyfish ("jellyfish"), the species of the genus Atolla are known to us as jelly fish. Like many other bioluminescent animals, jellyfish use light to hunt. The difference is the method: they turn their luminous body in roulette in order to hypnotize the victim and give a fatal strike.
1 - Fish-stained hand
This fish joins two curious features. The first, less interesting, is that it has spotted all over, like a jaguar. But Brachionichthys hirsutus , natural waters of Australia, is notorious for having small arms in front of the body, allowing you to swim in the ocean or "walk" along the seabed.

The colossal squid- ( Mesonychoteuthis hamiltoni) is probably the largest existing delula species, and the only member of the genus Mesonychoteuthis .The colossal squid-it is considered the largest invertebrate in terms of mass of the planet that is known, and can exceed 15 meters in length. [ citation needed ]
Biology
The Mesonychoteuthis hamiltoni head has the largest of all types of cells, even exceeding the Architeuthis in size and robustness. The colossal squid, also has the largest eyes in the animal kingdom reaching the size of a plate. It has two huge, sharp beaks and claws swivel-shaped hooks, deeply set in its tentacles.
Inhabits the depths of the Southern Ocean.
Little is known about the life of this creature. It hunter like other squid in the deep sea and using bioluminescence to find prey. Based on the capture of squid beak in the sperm whale stomachs, it is estimated the size of adult animals (since few were captured) of at least 22 meters in the case of adults, while younger about 10 meters.
Many sperm whales carry scars caused by the tentacles of the colossal squid, which have hooks instead of suckers that can cause deep wounds. The colossal squid-is a major prey for sperm whales that feed in the Southern Ocean; 14% of squid tentacles found in these whales are the colossal squid.
Recently the New Zealand fishermen found in Antarctic waters a colossal squid-over 14 meters long. The mollusk that weighed 495 kilos had eyes diameter plates of food. The animal was hooked by accident, brought on board and kept on ice, being sent to study at Auckland University of Technology, New Zealand. This most colossal squid-sample ever found is on display at the Museum of New Zealand Te Papa Tongarewa in Wellington.
When referring to size, it is important to distinguish between the total size and the size of the mantle.The total size refers to the size of the garment (the "head" of squid) plus the size of the tentacles. This measure is not the best, because the animal can be stretched, thus changing the size. There are reports that the first Architeuthys spp described, found stranded on a beach, I had 22 meters, just by the elasticity of the tentacles, so it is important not to review the part information. The mantle is one of the best measures, refers only to the "head" of the squid.
The colossal squid, unlike the giant-squid ( Architetus ) as it grows acquires a round shape in his head. The tentacles of the colossal squid-are great to grab the prey in icy Ross Sea. Then the body just floats while their tentacles seeking prey. For this buoyancy, the dying cells rise to the surface. This is a very common way to find giant or colossal squid.
