Bombina maxima, commonly known as the Yunnan firebelly toad or large-webbed bell toad, is a species of toad in the family Bombinatoridae found in Yunnan, China and likely to Myanmar.

[2] Its natural habitats include swamps, springs, marshes, arable land, canals, and ditches.

[3] Although easy to care for, handling a large-webbed toad should be kept to a minimum because their skin secretes a toxin that can cause irritation[4] This toxin is rich in active proteins and antimicrobial peptides that are essential in maintaining its innate immunity and protecting it from predators that come in contact with its skin.

[5] This antimicrobial peptide rich skin is used for local medicine.
