Shellfish is a culinary and fisheries term for exoskeleton-bearing aquatic invertebrates used as food, including various species of molluscs, crustaceans, and echinoderms. Although most kinds of shellfish are harvested from saltwater environments, some kinds are found only in freshwater. In addition a few species of land crabs such as Cardisoma guanhumi, are eaten, for example in the Caribbean.
Familiar marine molluscs enjoyed as a food source by humans include many species of clams, mussels, oysters, winkles, and scallops. Some crustaceans commonly eaten are shrimp, prawn, lobster, crayfish, and crabs.
Echinoderms are not as frequently harvested for food as molluscs and crustaceans, but sea urchin roe is quite popular in many parts of the world.
Most shellfish eat a diet composed primarily of phytoplankton and zooplankton.
Shellfish are among the most common food allergens.
The term shellfish is used both broadly and specifically. In common parlance, as in having "shellfish" for dinner, it can refer to anything from clams and oysters to lobster and shrimp. For regulatory purposes it is often narrowly defined as filter-feeding molluscs such as clams, mussels, and oyster to the exclusion of crustaceans and all else.
Although the term is primarily applied to marine species, edible freshwater invertebrates such as crayfish and river mussels are also sometimes grouped under the umbrella of "shellfish".
Although their shells may differ, all shellfish are invertebrates. As non-mammalian animals that spend their entire lives in water they are "fish" in the historic sense; however the denotion finfish (or fin fish) has been developed to distinguish fish as animals defined by having vertebrae from shellfish in modern terminology.
The word "shellfish" is both singular and plural; the rarely used "shellfishes" is sometimes employed to distinguish among various types of shellfish.
Archaeological finds has shown that humans have been making use of shellfish as a food item for thousands of years. In the present, shellfish dishes are a feature of almost all the cuisines of the world, providing an important source of protein in many cuisines around the world, especially in the countries with coastal areas.

The largehead hairtail (also beltfish), Trichiurus lepturus, is a member of the cutlassfish family, Trichiuridae. It is a long, slender fish found throughout the tropical and temperate waters of the world. The Atlantic and Pacific populations are also known as Atlantic cutlassfish and Pacific cutlassfish, respectively.
Largehead hairtails can grow to 2.34 m (7.7 ft) in length; the largest recorded weight is 5 kg (11 lb) and the oldest recorded age is 15 years.[1] They prefer coastal regions and sometimes enter estuaries. They are found at depths of 0 to 589 m (0 to 1,932 ft) with most records between 100 and 350 m (330 and 1,150 ft).
Behavior
Juveniles participate in the diel vertical migration, rising to feed on krill and small fish during the day and returning to the sea bed at night. This movement pattern is reversed by large adults, which mainly feed on fish.[1] Other known prey items include squid and shrimp, and the highly carnivorous adults regularly cannibalise younger specimens.
Spawning depends on temperature as the larvae prefer water warmer than 21 °C (70 °F) and are entirely absent at less than 16 °C (61 °F). Consequently spawning is year-round in tropical regions, but generally in the spring and summer in colder regions.
Fisheries and usage
Largehead hairtail is a major commercial species. With reported landings of more 1.3 mill. tonnes in 2009, it was the 6th most important capture fish species. By far the largest catches were reported by China (1.2 mill. t.) from the NW Pacific (FAO Fishing Area 61); other countries reporting significant catches were South Korea, Japan, and Pakistan.[4]
In Korea, the largehead hairtail is called "? (Kalchi):sword fish",in which "?(Kal)" means sword and "?(chi)" means fish, and is popular for frying or grilling. In Japan, where it is known as tachiuo ("太刀(tachi)":sword, "鱼(uo)":fish), they are fished for food and eaten grilled or raw, as sashimi. They are also called "sword-fish" in Portugal and Brazil (peixe-espada), where they are eaten grilled or fried. Its flesh is firm yet tender when cooked, with a moderate level of "fishiness" to the smell and a low level of oiliness. The largehead hairtail is also notable for being fairly easy to debone.
Fish
Fish is a kind of animal that lives in the water.There are two types of fish,the fresh water fish and the sea water fish.Fresh water fish,quite obviously,lives in rivers and lakes where they can find fresh water.On the other hand,sea water fish lives in the salty water in the sea.Fish has very high value for human beings.First they are very popular food.People even eat raw fish meat in some place like Japan or Tailand.Second fish is very important for maintaining the balance of the water environment.Fish places a very essential role in the food chain.
Birds
Birds have always been considered as a fascinating creature.Flying is still one of the biggest dreams of humans.Birds inspired us to build airplanes,the fastest way to travel as far.In ancient poems,birds always played the lovely messager between lovers.To most people,bird is a sympol of postive,bright,romance,and an up-going spirit.
