imags and names of a variety of examples of gastropods

 


Achatina fulica, India. The "Giant African Snail" has become a problem wherever it has been introduced. Originally from East Africa, humans have distributed it throughout South and Southeast Asia, and to many of the Pacific Islands.

Haminoea linda, South Pacific. The shells of these and similar opisthobranchs are transparent and colorless. The color and pattern seen here is on the mantle and is showing trough the clear, transparent shell. When the animal dies, the shells often wash up on beaches and are hard to distinguish from the bubbles produced by waves splashing on the shore.
Red abalone are found in inter-tidal areas attached to rocks from 20-100 feet. The depth changes from one area to another depending on environmental factors. In the southern parts of California, it has been found deeper than fifty or sixty feet. Farther north, closer to southern Oregon, it can be found from the low tide zone out to about fifty feet. It prefers water from forty-five to about 60 degrees Fahrenheit.
The Florida horse conch is the largest snail to be found in the American waters, sometimes reaching a length of two feet. It has ten whorls, and its shoulders bear large, low nodules. The operculum is a leathery brown color, the aperture is orange, and the animal itself is brick red in color.
