Identifying Blind Snakes in Thailand

With their tiny scales and barely visible eyes, Blind Snakes won’t be confused with any other snake species. However, their lack of features makes them difficult to distinguish from each other. You might need to inspect minor features of scales, which are described in this Key to Blind Snakes of Thailand. Another useful resource is Systematics of the Blindsnakes.
