Snail coming out of its shell (P. bridgesii).

Closed shell (P. bridgesii). Pomacea-Asolene, Marisa, Pomacea and Pomella. Depending on the specific snail.

all found in the New World (South America, Central America, the West Indies and the Southern U.S.A.) Apple snails live generally in ponds and rivers. They are abundant in Florida

Male snails creep up on their partners to breed. This can take from and hour up to a whole day. They breed quickly laying from 100 to 1000 eggs.

Apple snails breathe with an interesting combination of gills and lungs. They use a unique siphon to breathe air when the dissolved oxygen level is low in a pond. This system also comes in useful when the snail needs to migrate out of the water for food. When they go to lay their eggs they can lay them out of the water for a lessened threat of fish eating the eggs.

A Radula is a row of teeth used for tearing plant material

The muscular foot is not only used for movement, but it is also used as a sort of protection. The shell door is attached to the foot of the snail and it is very hard to open that door.

The volume of an Apple Snail can be determined by using the following equation: Volume = 1/3Pi * (Shell width/2)^2 * Shell length Baby snails can be 2.5 cm /1 inch (2-5 months)
