Sculpture above periphery of whorls consisting of nodes arranged in vertical and spiral rows. Radial striations present on shell but not on apex. The horntail snail belongs to the genus Macrochlamys (family Ariophantidae), which has over a hundred described species distributed from South to Southeast Asia and southern China (Pholyotha et al.

It can grow to a length of 16 inches (400 millimeters) and is easily identifiable by the left-handed opening of the shell - meaning when you look at the shell, the opening is on the left. Penis with 3-7 papillae along right margin and a projection with 1-4 papillae near end on left side (Figs. It is hoped that this manual will stimulate other biologists to contribute to our knowledge of freshwater mollusks. (Lamark, 1822). 160, 163, 166). (Fig. (Morelet, 1851). Officials in Florida are again battling a highly invasive, extraordinarily destructive giant snail species that also happens to be capable of spreading parasitic worms that invade human brains . 1945.

Aperture relatively shorter, about half or less the length of the shell. Sculpture consisting of incremental striations only. It was well received, and it served the interests and needs of many people. After a few years in storage glandular tissues in the female reproductive system deteriorate, and the process gradually spreads to destroy all but the terminal genital structures. Shell medium to large (12-75 mm). Apex of shell flat-topped, but sunken below periphery of last whorl. According to the Florida Department of Agriculture and Consumer Services (FDACS), the giant African snail, commonly referred to as GALS by invasive-species aficionados, is native to East Africa .

Maiden Campeloma Floridobia wekiwae Published April 18, 2013 Mesa Rams-horn Formalin will corrode the shell and thereby eliminate color, delicate sculpture, and the periostracum the thin skin coating present on most shells. Live snails for shell studies should be preserved in 70 percent alcohol. Until recently the entire knowledge of the Florida freshwater snail fauna was based on miscellaneous papers dealing with single species, groups of closely related species or single river systems. Base of shell with dark red spiral band. Operculum spiral, consisting of two or more rapidly increasing whorls (Fig. Some species are dioecious with a normal representation of males and females.
