Wonderful collection of sea shells

Замечательная коллекция морских раковин

The shell (akin to the word "cancer") is an external protective skeletal formation covering the body of some invertebrates and microorganisms. Conchology studies the shells of invertebrates. The greatest interest in terms of practical use and collectibles are the shells of mollusks.

Shell accumulations of various groups of organisms play an important role in the formation of some types of bottom sediments and sedimentary rocks.

Diatom skeletons, accumulating on the seabed, form diatom silts, which later turn into diatomite, tripoli, and flask.

The accumulation of shells of plankton foraminifera leads to the formation of globigerin silts, named after one of the genera (Globigerina). The shells of large foraminifera - fuzulinide and nummutidide can play a significant role in the formation of limestone.

The shells of mollusks participate in the formation of shell limestone, and the accumulations of shells of pantopus mollusks form pteropod mud.
