In contrary, shell spikes, as they appear in many marine gastropod species, are a construction of the ostracum layer. In contrary to those two shell layers produced in the apertural area of the shell, there is another which is made all over the pallium (mantle) on the inside of the shell. Mantle tissues are in direct contact with the shell. The shell of a gastropod is a shell that is part of a gastropod or snail's body. All marine gastropods, as well as some fresh water gastropods, breathe with gills. Gastropods are the most abundant mollusks: There are approximately 40,000 living species and 50,000 fossil species. The body moves from the back area to the front region, which causes a rotation so that the mantle cavity, which includes the anus, shell, and visceral mass, rotate about 180 degrees and are placed suddenly above the head and it seems that the shell is back. Some species reverse torsion ("detorsion"), but evidence of having passed through a twisted phase can be seen in the anatomy of these forms.
