King crab

 

The Life of Animals | King crab | Golden king crab, Lithodes aequispinus, is captured on the coast of Alaska in the Aleutian chain. Gold king crab is significantly smaller than the king crab red and blue, about 5-8 pounds (2.3 to 3.6 kg). It tastes like the red and blue king crabs, though perhaps sweeter. Note to occur in waters deeper than red king crab, often in the depths of 300 miles (1,800 feet, 550 m). Crabs king's golden youth are intricate and confidence in the structure-forming sessile invertebrates growing on the seabed like corals, sponges, sea whips provide Habitat. Habitat is the main factor that separates the range of red and blue king crabs in the Bering Sea.

 

 

Red king crab, Paralithodes camtschaticus, is a large species, reaching a thickness of 11 heavy shells (28 cm) and a leg extension 6 feet (1.8 m). Its natural range is the Bering Sea, the Aleutian Islands and St. Lawrence Island. You can now also in the Barents Sea and Arctic Europe, where it is drawn, and now it has become a plague of blue king crab, Paralithodes platypus, lives near St. Matthew Island, Pribilof Islands, and the Diomede Islands, Alaska and they are the people of Japan and the Russian king crab from Pribilof Islands are the largest of all king crab, sometimes more than 18 LB (8 kg) weight.

Hermit Crab

 

 

The Life of Animals | Hermit Crab | Most species have long, spirally curved abdomens, which is soft, unlike the hard, calcified abdomens appear in crustaceans. Protected from predators by a salvaged empty seashell Hermit Crab wounded abdomen, where the whole body back. The top of the abdomen is adapted to clasp strongly onto the columella of Cancer hermit snail shell. HERMIT CRAB, as its size increases, it becomes the shell find a large, and not before. The habit of living, but the shell gives the popular name "hermit of Cancer", by analogy with the hermit, who lived a few Hermit Crab species, and land and sea, as "vacancy chain" of the new BUZZ When new, the clay is, hermit crabs collected and formed of all the surrounding him from the modes of the greatest to the least. Cancer Cancer is brought to the maximum with the shell, the maximum time it was published before the new shell is the shell of Cancer,

Hermit Crab species range in size and shape, a species with a few heavy shells religious brevimanus mm long, can live 30-70 years and were approaching the size of a pain. Shell-less hermit Cancer Birger robber (Coconut Crab) This is a terrestrial invertebrates. Hermit Crab zoea larvae hatch, especially in the third stage. Many marine species of hermit crabs is common in the marine aquarium trade. Nearly 15 species of terrestrial world, the following are commonly kept as a concern: Caribbean Hermit Crab (religious and shielded), the Australian land hermit Crab (religious variable) and the Ecuadorian Hermit Crab (religious compressed).

Yeti Crab

 

  
The Life of Animals | Yeti Crab | K. hirsuta was discovered in March 2005, a group organized by Robert Vrijenhoek of the Monterey Bay Aquarium Research Institute in Monterey, Calif. And Michel Segonzac of the Ifremer and the Census of Marine Life scientist's use of the submarine DSV Alvin, operating from RV Atlantis. The discovery was announced March 7, 2006. Hairy pincers contain filamentous bacteria, which the creature can be used to neutralize toxic minerals from the water emitted by the hydrothermal vents, where he lives.

The term "furry lobster" is usually used for family Synaxidae. McPherson et al. Named the genus Kiwa after "goddess of shellfish in Polynesian mythology," but it is the sea in Maori mythology Kiwa Guardian Hirsuta means "hairy" in Latin.

Woodlouse

  

The Life of Animals | Woodlouse | The woodlouse has a shell-like exoskeleton, the which it must progressively shed as it grows. Metabolic rate is temperature-dependent in woodlice. Woodlice need moisture Because They rapidly lose water by excretion and through Their cuticle, and so are usually found in damp, dark places, Such as under rocks and logs, although one species, Hemilepistus reaumuri, inhabits "the driest habitat conquered by any species of crustacean ".

Woodlice then recycle the Nutrients back into the soil. Such as artificial environments in greenhouses where it can be very moist, woodlice may Become abundant and damage young plants. Few woodlice have returned to water. Other examples include some Haloniscus species from Australia (family Scyphacidae), and in the northern hemisphere Several species of Trichoniscidae and Thailandoniscus annae (family Styloniscidae). Species for the which aquatic life is assumed include Typhlotricholigoides aquaticus (Mexico) and Cantabroniscus primitivus (Spain).

Woodlice are Eaten by a wide range of insectivores, but the only animals known to prey exclusively on woodlice are spiders of the genus Dysdera, Such as the woodlouse spider Dysdera crocataThere are over 40 native or naturalised species of woodlouse in the British Isles, ranging in color and in size (3-30 millimeters or 0.1-1.2 inches) of the which only five are common: Oniscus asellus (the common shiny woodlouse), Porcellio scaber (the common rough woodlouse), Philoscia muscorum (the common striped woodlouse), Trichoniscus pusillus (the common pygmy woodlouse) and Armadillidium vulgare (the common pill bug).

Prawn

  

The Life of Animals | Prawn | Together with other swimming Decapoda, Dendrobranchiata show the "caridoid facies", or shrimp-like form. Generally the body is slightly flattened side-to-side. The biodiversity of Dendrobranchiata decreases markedly at Increasing Latitudes most species are only found in a region of the between 40 ° north and 40 ° south. Some species may occur at higher latitudes.

Some species of Sergestidae live in fresh water, but most Prawns are exclusively marine. Species of Sergestidae, Benthesicymidae and Sergestidae Mostly live in deep water, and Solenoceridae species live offshore, while most Penaeidae species live in shallow inshore waters, and Lucifer is planktonic. Prawns are "opportunistic omnivores", and Their diet can include a range of food items from fine particles to large organisms. These may include fish, chaetognaths, krill, copepods, radiolarians, phytoplankton, nematocysts, ostracods and detritus.

Dendrobranchiata are of huge importance. While in some countries, Such as the United States, production is almost entirely through fisheries, other countries have concentrated on aquaculture (shrimp farms), including Ecuador where 95% of production is farmed some countries Produce similar amounts from fisheries and aquaculture, including Mexico, China, India and Indonesia.

Species from the family Aristeidae are Important to deep-water fisheries, particularly in the Mediterranean Sea, where Aristaeomorpha foliacea is caught by trawlers. In Brazil, Aristaeomorpha foliacea, Aristeus antillensis Aristaeopsis edwardsiana and are of commercial importance. The most Important species for aquaculture are Marsupenaeus japonicus (Kuruma prawn), Fenneropenaeus chinensis (Chinese prawn), Penaeus monodon (giant tiger prawn) and Litopenaeus vannamei (whiteleg prawn)

Lobster

 

The Life of Animals | Lobster | Lobsters are invertebrates with a hard protective exoskeleton. Like most arthropods, lobsters must molt in order to grow, the which leaves Them Vulnerable. Although, like most other arthropods, lobsters are largely bilaterally symmetrical, They Often possess unequal, specialized claws, like the king crab. The lobster's head bears the antennae, antennules, mandibles, the first and second maxillae, and the first, second, and third maxillipeds. Because lobsters live in a murky environment at the bottom of the ocean, They Mostly Their use antennae as sensors. The lobster eye has a reflective structure above a convex retina.

Lobsters, like snails and spiders, have blue blood due to the presence of haemocyanin the which contains copper (in contrast, vertebrates and many other animals have red blood from iron-rich hemoglobin). Lobsters possess a green hepatopancreas, Called the tomalley by chefs, the which functions as the animal's liver and pancreas. In general, lobsters are 25-50 centimetres (10-20 in) long, and move by SLOWLY walking on the sea floor. Lobsters are found in all Oceans.

Lobsters are omnivores and eat live prey typically Such as fish, mollusks, other crustaceans, worms, and some plant life. Although lobster skin has been found in lobster stomachs, this is Because lobsters eat Their shed skins after molting. Lobsters may also be killed or rendered insensate IMMEDIATELY before boiling through a stab into the brain, in the belief That Will this stop Suffering.

Lobster is fished in water the between 1 and 500 fathoms (2 and 900 m), although some live lobsters at 2.000 fathoms (3.700 m).Agrowing niche lobster fisher may as many as 2.000 traps. Around the year 2000, due to overfishing and high demand, lobster aquaculture expanded. As of 2008, no lobster aquaculture operation Had achieved commercial success, Mainly due to the fact That lobsters eat each other (cannibalism) and the slow growth of the species these two problems make it Difficult to Make lobster aquaculture profitable.

Crab

 

The Life of Animals | Crab | Generally Crabs are covered with a thick exoskeleton, and armed with a single pair of chelae (claws). Crabs are found in all of the World's Oceans, while many crabs live in fresh water and on land, particularly in tropical regions. Crabs Vary in size from the pea crab, A Few millimeters wide, to the Japanese spider crab, with a leg span of up to 4 meters (13 ft). About 850 species of crab are freshwater, terrestrial or semi-terrestrial species They are found throughout the world's tropical and semi-tropical regions.

The earliest unambiguous crab fossils date from the Jurassic, although Carboniferous Imocaris, known only from its carapace, may be a primitive crab. Often Crabs show marked sexual dimorphism. Often males have larger claws, a tendency the which is particularly pronounced in the fiddler crabs of the genus Uca (Ocypodidae). In fiddler crabs, males have one Claw the which is greatly enlarged and the which is used for communication, particularly for attracting a mate Another conspicuous difference is the form of the pleon (abdomen); in most male crabs, this is narrow and triangular in form, while females have a broader, rounded abdomen.

Some crabs, Notably the Portunidae and Matutidae, are also capable of swimming. Crabs are Mostly active animals with complex behavior patterns. Crabs growing niche to be aggressive males Towards Often one another and fight to gain access to females. Crabs are omnivores, feeding primarily on algae, and taking any other food, including molluscs, worms, other crustaceans, fungi, bacteria and detritus, Depending on Their availability and the crab species. The evolution of crabs is characterized by an increasingly robust body, and a reduction in the abdomen. Although many other groups have undergone similar processes, carcinisation is most advanced in crabs.

The movement of the female gonopore to the sternum defines the clade Eubrachyura, and the later change in the position of the male gonopore defines the Thoracotremata. It is still a subject of debate whether Those crabs where the female, but not male, gonopores are situated on the sternum, form a monophyletic group
