Amber snail

Description:

These small, yellow to beige snails with dark brown shells were all over the grass after the rain. Each snail was about the size of a thumb nail.

Habitat:

In the grass next to a small pool of standing water.

Notes:

Not sure if the different individuals are of the same species. As per the reference: “An amber snail's aperture rim is sharp and there is no apertural lip. In this regard, amber snails are similar to pond snails (Lymnaeidae). Between different populations there may often be extreme, even hereditary, differences in size, which sometimes makes the determination of species difficult... The exact separation of the different species of amber snails, however, remains very unclear. On one hand, the different species externally are very similar. Besides, most amber snail species are quite variable in their appearance... While the former two species are usually quite easily distinguished in their shell form, in other cases a clear distinction is only possible with anatomical means. Apart from that, many amber snail findings so far have not yet been confirmed by anatomical examinations... So there still is a large need for research, as well concerning amber snail ecology, as the distinction of species.” In New York, there are at least 4 amber snails in the Oxyloma genus (O. effusum, O. groenlandica, O. peoriense and O. retusum). http://explorer.natureserve.org/servlet/...
