Status:

Red-bellied Water Snake (Nerodia erythrogaster) is primarily a southern species, extending north into Maryland on the Eastern Shore coastal plain. This distinctive snake inhabits swamps, ponds, lakes and rivers, especially in bottomlands. Red-bellieds usually feed on amphibians (especially frogs) or fish, but will consume other suitable prey items if available (Tennant, 2003). Red-bellied Water Snake is ranked as S2 (state rare)-S3 (watch list) in Maryland due to its restricted distribution (Maryland DNR site).

There are 22 records in the project database.
