The water cockroach does not look like a red or black cockroach in appearance and way of life. The marine pest can be attributed to the largest crustaceans. It can be compared with krill, shrimps, lobsters. The body length is about 10 cm. The location of the eyes contributes to a large radius of vision. The organs of touch are sensilla - hairs, with the help of which the owner explores everything around.
Habitat
The largest sea cockroach ever caught.
Habitats - bottom and coastline, depth up to 290 UAH. Area - Baltic Sea, Pacific Ocean, Arabian Sea, freshwater lakes. Crustaceans prefer salty sea water. Of the 75 species, most live in the sea. Several species live in freshwater lakes. A huge number of individuals were noted in Lake Ladoga, Vättern and Venern.
Scientists still do not understand how the cockroach got into the sea and ocean. According to one version, arthropods lived in such an environment even at the time when the One Ocean existed. Other researchers believe that these are the consequences of migration.
The diet of sea cockroaches
The main food is at the bottom of the reservoir, much less often - on the coastline. The diet consists of a variety of algae, small fish, caviar, small arthropods, organic remains of marine life, their fellows.
They are able to survive in any conditions due to unpretentiousness in nutrition and cannibalism. Sea cockroaches are real predators.
Life cycle of sea cockroaches
Sea cockroaches.
The process of fertilization is the mating of female and male individuals. The place for laying eggs is sand. The larvae emerge from the eggs after the end of the nutrient supply. The body of the larva has 2 segments. Due to the soft shell, the crustacean can receive mechanical damage. This phase is called the nauplius.
Near the anus, there is an area that is responsible for the metanauplius - the next stage, when the process of strengthening the carapace occurs. Further, there are changes in appearance and several lines. In parallel, the development of internal organs is underway. When the shell reaches its maximum size, the formation stops.
Sea cockroaches and people

The relationship between people and outlandish cockroaches did not work out. First of all, because of their disgusting appearance. Animals are edible, especially since the closest relatives of shrimps and crayfish are eaten with pleasure by people.
On the territory of Russia they are not met. Sometimes they accidentally get into a jar of sprat, which spoils the impression for people. Although sea cockroaches do not affect the taste, the appetite from an unpleasant find can deteriorate.
Conclusion
This species is considered unique among other relatives. Sea cockroaches are a delicacy in countries where exotic cuisine is present. In the countries of the former CIS, arthropods are not cooked due to their repulsive appearance and the lack of demand for such dishes.
