They are known to take larger prey, such as small vertebrates (frogs, mice, etc.), which are sometimes beaten against a stone before swallowing. [1] The ten Batrachostomus frogmouths are found in tropical Asia. They have smaller, more rounded bills and are predominantly insectivorous.
The tawny frogmouth was first described in 1801 by the English naturalist John Latham. [4] Its specific epithet is derived from Latin strix 'owl' and oides 'form'.

Anatomy of a wood frog tadpole (Lithobates sylvaticus) As a frog tadpole matures it gradually develops its limbs, with the back legs growing first and the front legs second. The tail is absorbed into the body using apoptosis. Lungs develop around the time as the legs start growing, and tadpoles at this stage will often swim to the surface and ...
The amount of entrained water the frog can ingest is related to its ability to actively increase its body volume. The frog's buccopharyngeal cavity (the cavity connecting the mouth and the pharynx) is very distensible and can expand substantially. It uses its entire trunk to rapidly enlarge the cavity, which expands into the lower end of the trunk.
