The openbill storks or openbills are two species of stork (family Ciconiidae) in the genus Anastomus. They are large wading birds characterized by large bills, the mandibles of which do not meet except at the tip. This feature develops only in the adults. Both species feed predominantly on molluscs. The roof of the upper bill is fringed with plate-like structures ("lamellae") in the African openbill, but these are absent in the Asian openbill.[2][3]
