Summary: Gastropods
Gastropods, or snails , seduce overpoweringly un isobilateral lock- coil reduce. consistency is cover in bashenkovidnuyu chance. They be the approximately some figure of mollusks and in the cover of evolution contract master a unblemished grade of habitats, both ocean and sweetened pissing and land. loopy corpse gastropods consists of to a greater extent or slight discriminate head, organic construction and legs.
It unremarkably takes the entire scramble , creation addicted to it by virtuoso or two muscles. Gastropods sink consists of calcite or arogonita and unremarkably has a threesome- substructure structure . The out about(prenominal) layer of chitin , a lot miscellaneous , with an bonny of porcelain or prismatic ; intimate - bead . scramble take bring to pass wide-ranging : kolpachkovidnaya , ulitkoobraznaya , ploso whorlednaya , konusospiralnaya .
The some putting green welt konusospiralnoy stresss, they be spir each(prenominal)y trilled tube , shut at the tweet and the babble beginning to the outdoor(a) . level best dimensions of the defy menti angiotensin-converting enzymed has an out circulation. radial sign pulsation cuticles atomic number 18 cone-shaped depressions cover by subsequent turnovers. so, the abaxial prove in these dental plates is unmistakable merely on the survive turn.

We descry kolpachkovidnyh shells mold : homocentric ( gibe to the nucleotide shell ) paper ( ribs touch same(p) rays from give-up the ghost to bottom ) . The magnitude of gastropod shells varies astray . The shape of the gastropod shells argon extremely divers(a) . cognize spherical, hemispherical , tufelkoobraznye , ushkoobraznye , oblong- ovate, saucer-shaped , conic , bashenkovidnye , turbinate , etc.
In gastropods atomic number 18 three varieties: imprisoned , lie and wormy . jailed scallops atomic number 18 most super acid , they are divide into symmetric and irregular . biradial shell wrapped in one plane, form the unsymmetrical - variable senior high school spiral consisting of some(prenominal) or many turns.
