Shrimp photo and description, origin, lifestyle and reproduction

Shrimps, or real shrimp (lat. Caridea) infraorder of crustaceans from the order of decapods (Decapoda).


Shrimp is considered the most common crustacean, it is used as food by both representatives of the animal world and humans.

Seas, oceans, fresh water reservoirs are excellent habitat and breeding grounds for shrimp. They are especially valued for their taste properties, they are considered a delicacy, so they are used in cooking.

The shrimp is called an unusual, mysterious inhabitant of the aquatic environment.

Contains a large amount of protein, calcium, therefore it is a low-calorie food.

Life span from one to five and a half years.


Belongs to the decapod order, which includes more than 2000 different species and subspecies. Their body is covered with a chitinous skeleton, which the animal sheds from time to time, t.e. has the ability to shed.


There are more than a hundred different commercial species that people use as their favorite food. For these purposes, special shrimp farms are equipped.

For home breeding in aquariums, there are varieties that successfully live and develop in artificial conditions.

They are classified into freshwater, cold water, warm water and brackish water:

  1. Russia, waters of Australia, South Asia freshwater shrimp habitats.
  2. North, Baltic, Barents Sea, Greenland, Canada inhabited by cold-water shrimp.
  3. The southern coast is teeming with warm-water clams.
  4. Brine shrimp are common in salt waters.
  5. The South American coast, the Black and Mediterranean Seas are the habitat of the Chilean crustaceans.
  6. The king prawn is found in the Atlantic Ocean.


Depending on the species, shrimp differ in color, size and behavior. The body of an arthropod is elongated, flattened in the lateral part. Consists of a cephalothorax and abdomen, the predominant colors in color are gray-green, pink, blue, with stripes or spots.

The animal grows in size from 1 to 32 cm.

The organ of vision the eye, consists of a plural number of facets, the number of which increases from year to year. The arthropod perfectly sees close objects due to mosaic vision. It is the visual organs that produce a special hormone that is involved in the regulation of processes:

  1. Changes body color.
  2. Participate in the growth of an individual.
  3. Influences the number of lines.
  4. Determines the amount and location of the pigment.
  5. promotes calcium accumulation and metabolism.

The organ of touch looks like the anterior antennae of the antennae. On the abdomen are five pairs of legs that help swim. On these legs, pleopods, the female bears her offspring.

The shrimp moves and thereby washes and cleans its eggs. With the help of flexion movements of the abdomen, the arthropod can quickly move backward.

The jaw limbs help to collect food and bring it to the mouth.

The front pair of legs of the shrimp are presented in the form of claws. With their help, the shrimp can defend itself and, in case of danger, defend itself with their help. The claw can grab larger prey. The claws of males are much more developed than those of females. Left and right legs can move in different directions at the same time.

The shrimp breathes with the help of gills hidden in the shell. A large blade in the thoracic region helps in the water to pass through the gills and release oxygen.


Shrimp habitat seas and oceans, arthropods are ubiquitous.

The young crustacean feeds exclusively on the purest plankton, which makes its meat a particularly valuable and high-quality product.

Scavenger shrimp, feed on any organic debris. Plankton, juicy algae leaves, soil particles, young fish are considered a favorite delicacy. The organs responsible for smell and touch in the form of antennae antennae help the shrimp find food.

Some individuals look for vegetation in the ground, others at the bottom.

Due to low vision, arthropods see almost nothing in the water at a long distance.

The olfactory organs help to find food and hunt. With the help of developed jaws and mandibles, the shrimp grinds and grinds the victim, this process can take 2-3 hours.

As a homemade food, the shrimp is fed with a prepared composition or boiled vegetables and fresh fruits. Shrimp eat leftover food from aquarium fish.

Character features

The arthropod is very mobile, maneuvers well with the help of walking and swimming legs located on the head, chest and abdomen. The tail stalk helps to bounce and move backwards. Shrimps are secretive, live alone. However, there are species that live in large groups.

Some representatives are active at night, others look for food only during the day. They spend their whole lives moving at the bottom, searching for food and hunting, and travel long distances.


All shrimp are hermaphrodites, t.e. bisexual. The formation of male and female glands falls on a different period of time. Puberty of a young shrimp begins with becoming a male and only after three years does it become a female. Eggs at the stage of formation look like a yellow-green mass.

Individuals mate very quickly, eggs soon appear, which subsequently become larvae. The process of formation of the larva takes from 10 days to a month.

The larvae are not capable of independent search for food, lead a sedentary lifestyle.

natural enemies

A large number of shrimp die in the larval stage. Arthropods are the favorite food of whale sharks, whales, and other planktivorous. Shellfish, seabirds, fish, some mammals also eat shrimp.

She is completely unarmed. The only way to escape from the enemy is to escape, she can hide in the seaweed.

Another feature is the possibility of masking. Shrimp mimic the color of the bottom and adjust the color of quinine to their surroundings. Animals are caught on an industrial scale. Producers extract from 2 to 3 million. tons of arthropods annually.


Due to the high fecundity and ability to self-regulate, the shrimp maintains its population at a stable level. Even natural enemies, low survival rate of larvae, as well as industrial trapping do not cause much damage to the population.

The following features stand out:

  1. When there is a significant reduction in the number of arthropods, individuals begin to reproduce more actively.
  2. If there is a shortage of food, then females bring offspring much smaller in number.
  3. Arthropods grown in clean cold water and in the natural environment are considered to be of the highest quality.
