Wonderful collection of sea shells

Замечательная коллекция морских раковин

The conch (akin to the word "cancer") is an external protective skeletal formation covering the body of some invertebrate animals and microorganisms. Conchiology is studying invertebrate shells. From the point of view of practical use and collecting, shell mollusks are of the greatest interest.

Accumulations of shells of various groups of organisms play an important role in the formation of certain types of bottom sediments and sedimentary rocks.

Skeletons of diatoms, accumulating on the seabed, form diatoms, which subsequently turn into diatomite, tripoli and flask.

The accumulation of shells of planktonic foraminifera leads to the formation of globigerin sludges, named after one of the genera (Globigerina). Shells of large foraminifera - fusulinide and nummulitide can play a significant role in the formation of limestone.

Shells of mollusks participate in the formation of shell limestones, and accumulations of shells of winged mollusks form pteropod silts.
