The Asian openbill stork (Anastomus oscitans) name is derived from the distinctive gap formed between the recurved lower and arched upper mandible of the beak in adult birds which allows it to catch its preferred food, the freshwater snails. The cutting edges of the mandible have a fine brush like structure that is thought to give them better grip on the shells. The Asian Openbill Stork has mainly gray plumage; glossy black wings and tail that may have a green or purple sheen and is found mainly in the Indian subcontinent and Southeast Asia.
