[17] [18] Unlike other modern amphibians (frogs and salamanders) the skull is compact and solid, with few large openings between plate-like cranial bones. The snout is pointed and bullet-shaped, used to force their way through soil or mud. In most species the mouth is recessed under the head, so that the snout overhangs the mouth. [10]

Hummingbird legs are short with feet having three toes pointing forward and one backward – the hallux. [17] [18] The toes of hummingbirds are formed as claws with ridged inner surfaces to aid gripping onto flower stems or ...
An affinity between the amphibians and the teleost fish is the multi-folded structure of the teeth and the paired supra-occipital bones at the back of the head, neither of these features being found elsewhere in the animal kingdom. [25] The Permian lepospondyl Diplocaulus was largely aquatic

Clawed frogs have powerful legs that help them move quickly both underwater and on land. Feral clawed frogs in South Wales have been found to travel up to 2 kilometres (1.2 mi) between locations. [11] The feet of Xenopus species have three black claws on the last three digits. These claws are used to rip apart food and scratch predators.
