Isopods are an order of marine invertebrates (animals without backbones) that belong to the greater crustacean group of animals, which includes crabs and shrimp.

This huge monopod is a member of the genus. They are thought to be abundant in deep and deep waters of the Atlantic Ocean and the Pacific Ocean. NOAA bent program 2006 Deep Adventure Adventure image provided. Download high resolution version (2.8 Mb)

Scientists estimate that there are about 10,000 isopods (both are in "equal legs"). They are one of the most diverse groups of every crustacean with various shapes and sizes, from microns to 0.5 meters in length. They also live in various kinds of habitats distributed all over the world, from mountains and deserts to the deep sea.

Equal legs usually look different but have common features. For example, all isopods have two sets of antennas, compound eyes, four pairs of jaws. The body of all isopods or pereon consists of seven parts, each with its own set of walking legs. The legs have a short abdomen of six segments called "pleons", and one or more of these segments fuse to the tail. Each fold has a series of legs with limbs called "limb legs" for swimming and breathing.

About half of known isopods live in the sea. Some are large and thorny, live in deep sea, others are very small and live in fish. People living in coastal waters and shelf waters, people moving over the ocean floor, and people living in plants are increasing.

Those equal legs living in the ocean can be achieved by gas exchange "breathing" by using their gastropods. People living on land developed their gastropods, including those called "pseudo balloons" that function as gas exchange organs that do not have to sink completely in the water.

The best known leg legs may be land pellets (sows or hibiscus) that can be crushed around any backyard in a damp, dark situation. The largest isophyll species is from the genus Basthynomus. These animals live in deep sea, and they are much bigger than shallow relatives (like many animals living there)

It is classified as a terrestrial animal and belongs to the crustacean class. Familiar crustaceans include lobster, crab, shrimp and otter (otter). In other words, crustaceans are part of a larger group of arthropods or arthropods. All arthropods have a hard outer stratum corneum, a segmented tree trunk, and limbs, and due to a hard cuticle, there are functions such as reproductive, gas exchange and excretion. In some species, the stratum corneum of gastropods folds to form a white branching capillary that forms the lungs of the lungs. The last pair of appendages, the uropod, protrudes from the back of the animal and is functionally sensuous and defensive.

It is composed of about 45,000 species distributed throughout the world, a member of crustaceans, crustacean subphylum (arthropoda), a group of invertebrates. Crabs, lobsters, shrimps and hibiscus are among the most famous crustaceans, but this group also includes various shapes without popular names. Crustaceans are usually aquatic organisms, unlike other arthropods, have two pairs of attachments (antennas and antennas) in front of the mouth and a pair of appendages with undulations near the mouth. However, due to many exceptions to the basic features, it is extremely difficult to build a satisfactory comprehensive definition of all crustaceans.

The legs belong to Malacostranka, a famous crustacean group, including familiar crustaceans such as shrimp, crab, lobster, krill. Unlike Malacho Strachan with obvious shells, isophoras do not have it. Equal foot belongs to Super Peracarida, which contains a wide variety of taxa, all of which are bred in abdominal pouches between the feet. Isopods are unique among these crustaceans for several reasons. Because they are devoid of shell, there is no sputum covered by other group shells so they have a professional flaky pleural pleura ("swimming legs") behind the body to breathe Use. In many island legs of the terrestrial, gastropods have a respiratory structure similar to that of the lungs. Internally, the heart is behind the chest to increase sputum circulation. Unlike all other crustaceans, isopods peel off the stratum corneum in two steps (called molting process) (two phase molting).
