Possibly GREEN APPLE SNAIL - “Blue” Variety
Pomacea (pomacea) bridgesii
Okay, this damn shot - the only one of it’s kind on the internet but it shows up in nearly every seach of snail that is conducted. it has been a bone of contention for me for awhile, it’s always THIS shot, so this has to be an anomaly of sorts. The snail is shown on land, but I believe it’s actually an Amazonian aquatic snail and a young specimen. The shell configuration is correct, and the Apple Snail comes in several color variations — ivory, yellow, blue and a series of browns. Thoughts?
Apple snails can be classed as somewhat amphibious, they have the ability to close a trap door called the operculum to prevent them drying out when buried in the mud or during dry periods in the wild.
Another brilliant adaptation they have is the branchial respiration system that can compare to the gills of our fish. On the right hand side it enables the snail to breath under water, and on the left hand side it works to respirate air. This lung/gill arrangement allows it to leave the water to search for food when food under the surface becomes scarce.
The Golden Apple Snail in Asia it has become a pest. It was introduced from Florida and Latin America to Taiwan in the early 1980’s to start an escargot industry. Consumers did not react as enthusiastically as the snail farmers did and the snail market declined. They are also now a problem in Indonesia, Cambodia, Hong Kong Japan and parts of China. The snails have found their way into the rice fields and are grazing on the rice shoots. It is costing farmers over one billion dollars in crop losses. They are being controlled somewhat by using catfish and ducks to help eradicate the snail population. So we see it is not a perfect world.
Painted Snail or Cuban Land Snail (pretty)
Haitian Land Snail (also green)
Giant African Snail
Mystery “Green Snail”
I have been trying to identify this mystery snail for awhile. Its picture has been floating around the net for awhile, of course without any kind of context :S
If you have decent input or are just interested in my ongoing project with terrestrial gastropod ID over the internet, then here’s some rumination.
* btw, though it is a green snail, it is clearly not the well known green snail, the Manus Isld Tree Snail (Papustyla pulcherima) from Papua New Guinea. (see one of those here).
