Tiny Fish That Will Give You Nightmares For A Week

The deep-sea dragon fish is a member of the Stomiidae family. There are many genera and over two hundred different species altogether in this family. The most known about is the Barbeled dragon fish.

Deep-sea dragon fish lives in the deep parts of the Atlantic Ocean beyond where any plant life grows or light reaches, hence its name. This habitat has caused the dragon fish to adapt to the conditions at these depths by having light-producing organs called photophores and skeletons that better suit deep-sea life.

The deep-sea dragon fish, as its name states, lives in the deep-sea of the Pacific Ocean. The Dragon fish tends to live around 1000 to 3000 meters below the surface.

Some dragon fish have even been found at depths of 5000 meters. At these depths, the conditions are very extreme. The pressure can range from 200 to 600 atmospheres and the temperatures fall just below four degrees Celsius. The dragon fish lives below the Bathyal zone where no light reaches.

The Bathyal zone starts at about 220 meters. Past this point, there is no light, and it is deep enough to not be affected by storms or ocean currents, making the environment where the dragon fish lives utterly still.

Giant Sea Creature That Will Scare You From Going Into Water

The sea is the connected body of salt water that covers over 70 percent of the Earth’s surface. The sea is important in moderating the Earth’s climate, and in providing food and oxygen, and in its enormous diversity of life, and for transport.

The study of the sea is called oceanography. The sea has been travelled and explored since ancient times, but its scientific study dates broadly from the voyages of Captain James Cook to explore the Pacific Ocean between 1768 and 1779.

Seawater is characteristically salty. The main solid in solution is sodium chloride, but the water also contains chlorides of potassium and magnesium, alongside many other chemical elements, in a composition that hardly varies across the world’s oceans.

However, the salinity varies widely, being lower near the surface and near the mouths of large rivers and higher in the cold depths of the ocean. The sea surface is subject to waves caused by winds. Waves decelerate and increase in height as they approach land and enter shallow water, becoming tall and unstable, and breaking into foam on the shore. Tsunamis are caused by submarine earthquakes or landslides and may be barely noticeable out at sea but can be violently destructive on shore.

Winds create currents through friction, setting up slow but stable circulations of water throughout the sea. The directions of the circulation are governed by several factors including the shapes of the continents and the rotation of the earth.

Huge Fish That Tipped Over A Ship

Since the end of the age of sail a ship has been any large buoyant watercraft. Ships are generally distinguished from boats based on size and cargo or passenger capacity. Ships are used on lakes, seas, an drivers for a variety of activities, such as the transport of people or goods, fishing, entertainment, public safety, and warfare. Historically, a “ship” was a vessel with sails rigged in a specific manner.

Ships and boats have developed alongside mankind. In armed conflict and in daily life they have become an integral part of modern commercial and military systems. Fishing boats are used by millions of fishermen throughout the world. Military forces operate vessels for combat and to transport and support forces ashore. Commercial vessels, nearly 35,000 in number, carried 7.4 billion tons of cargo in 2007.

Ships were a key in history’s great explorations and scientific and technological development. Navigators such as Zheng He spread such inventions as the compass and gunpowder. Ships have been used for such purposes as colonization and the slave trade, and have served scientific, cultural, and humanitarian needs. After the 16th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to the world’s population growth. Maritime transport has shaped the world’s economy into today’s energy-intensive pattern.

Ships can usually be distinguished from boats based on size and the ship’s ability to operate independently for extended periods. A commonly used rule of thumb is that if one vessel can carry another, the larger of the two is a ship.

Rare Lobster With Two Colors

Clawed lobsters comprise a family (Nephropidae, sometimes also Homaridae) of large marine crustaceans. They have long bodies with muscular tails, and live in crevices or burrows on the sea floor. Three of their five pairs of legs have claws, including the first pair, which are usually much larger than the others. Highly prized as seafood, lobsters are economically important, and are often one of the most profitable commodities in coastal areas they populate. Commercially important species include two species of Homarus from the northern Atlantic Ocean, and scampi – the northern-hemisphere genus Nephrops and the southern-hemisphere genus Metanephrops. Although several other groups of crustaceans have the word “lobster” in their names, the unqualified term “lobster” generally refers to the clawed lobsters of the family Nephropidae. Clawed lobsters are not closely related to spiny lobsters or slipper lobsters, which have no claws (chelae), or to squat lobsters. The closest living relatives of clawed lobsters are the reef lobsters and the three families of freshwater crayfish.

Lobsters are invertebrates with a hard protective exoskeleton. Like most arthropods, lobsters must moult in order to grow, which leaves them vulnerable. During the moulting process, several species change colour. Lobsters have 10 walking legs; the front three pairs bear claws, the first of which are larger than the others. Although, like most other arthropods, lobsters are largely bilaterally symmetrical, some genera possess unequal, specialised claws.

Lobster anatomy includes the cephalothorax which fuses the head and the thorax, both of which are covered by a chitinous carapace, and the abdomen.

Sea Creatures Made From Wool

Most fish exchange gases using gills on either side of the pharynx. Gills consist of threadlike structures called filaments. Each filament contains a capillary network that provides a large surface area for exchanging oxygen and carbon dioxide.

Fish exchange gases by pulling oxygen-rich water through their mouths and pumping it over their gills. In some fish, capillary blood flows in the opposite direction to the water, causingcounter current exchange. The gills push the oxygen-poor water out through openings in the sides of the pharynx. Some fish, like sharks and lampreys, possess multiple gill openings.

However, bony fish have a single gill opening on each side. This opening is hidden beneath a protective bony cover called an operculum.

Juvenile bichirs have external gills, a very primitive feature that they share with larval amphibians.

Fish from multiple groups can live out of the water for extended time periods. Amphibious fish such as the mudskipper can live and move about on land for up to several days, or live in stagnant or otherwise oxygen depleted water.

Many such fish can breathe air via a variety of mechanisms. The skin of an guillid eels may absorb oxygen directly. The buccal cavity of the electric eel may breathe air.

Catfish of the families Loricariidae, Callichthyidae, and Scoloplacidae absorb air through their digestive tracts. Lungfish, with the exception of the Australian lungfish, and bichirs have paired lungs similar to those of tetra pods and must surface to gulp fresh air through the mouth and pass spent air out through the gills.

Pictures Of Moray Eal That Sufocated By Trying To Eat A Pufferish

Moray eels are cosmopolitan eels of the family Muraenidae. The approximately 200 species in 15 genera are almost exclusively marine, but several species are regularly seen in brackish water and a few, for example the freshwater moray (Gymnothorax polyuranodon) can sometimes be found in freshwater. With a maximum length of 11.5 centimetres (4.5 in), the smallest moray is likely the Snyder’s moray (Anarchias leucurus), while the longest species, the slender giant moray (Strophidon sathete) reaches up to 4 metres (13 ft). The largest in terms of total mass is the giant moray(Gymnothorax javanicus), which reaches almost 3 metres (9.8 ft) and can weigh over 36 kilograms (79 lb).

The dorsal fin extends from just behind the head along the back and joins seamlessly with the caudal and anal fins. Most species lack pectoral and pelvic fins, adding to their serpentine appearance. Their eyes are rather small; morays rely on their highly developed sense of smell, lying in wait to ambush prey.

The body is generally patterned. Camouflage is also present inside the mouth. Their jaws are wide, framing a protruding snout. They possess large teeth, designed to tear flesh as opposed to holding or chewing.

Moray eels’ heads are too narrow to create the negative pressure that most fish use to swallow prey. Quite possibly because of this, they have a second set of jaws in their throat called pharyngeal jaws, which also possess teeth. When feeding, morays launch these jaws into the mouth, where they grasp prey and transport it into the throat and digestive system.

Pictures Of Only Kind Of Jellyfish That Glows In The Dark

Jellyfish (also known as jellies or sea jellies or a stage of the life cycle of Medusozoa) are free-swimming members of the phylum Cnidaria. Medusa is another word for jellyfish, and refers to any free-swimming jellyfish life stages among animals in the phylum. Jellyfish have multiple morphologies that represent cnidarian classes including the Scyphozoa (over 200 species), Staurozoa (about 50 species), Cubozoa (about 20 species), and Hydrozoa (about 1000–1500 species that make jellyfish and many more that do not).

Jellyfish are found in every ocean, from the surface to the deep sea. Some hydrozoan jellyfish, or hydromedusae, inhabit freshwater; freshwater jellyfish are less than an inch (2.5 cm) in diameter, are colorless and do not sting. Large, often colorful, jellyfish are common in coastal zones worldwide. Jellyfish have roamed the seas for at least 500 million years, and possibly 700 million years or more, making them the oldest multi-organ animal.

In its broadest sense, the term jellyfish may also generally refer to members of the phylum Ctenophora. Although not closely related to cnidarian jellyfish, ctenophores are also free-swimming planktonic carnivores, are generally transparent or translucent, and exist in shallow to deep portions of all the world’s oceans.

More specific names for the groups of Cnidarian jellyfish are scyphomedusae, stauromedusae, cubomedusae, and hydromedusae. These may relate to an entire order or class.
