The word amphibian is derived from the Ancient Greek term ἀμφίβιος (amphíbios), which means 'both kinds of life', ἀμφί meaning 'of both kinds' and βίος meaning 'life'. The term was initially used as a general adjective for animals that could live on land or in water, including seals and otters. [8]
The generic name Amphibamus alludes to the two modes of locomotion of the animal, swimming with its oar-shaped tail, and crawling because of its long fingers with claws, [5] from Greek ἀμφί (amphí) "both" and -βάμων (-bámōn) "that goes" or βᾶμα (bâma) "leg".

Temnospondyli (from Greek τέμνειν, temnein 'to cut' and σπόνδυλος, spondylos 'vertebra') or temnospondyls is a diverse ancient order of small to giant tetrapods—often considered primitive amphibians—that flourished worldwide during the Carboniferous, Permian and Triassic periods, with fossils being found on every continent.

Its name is derived from the short black claws on its feet. The word Xenopus means 'strange foot' and laevis means 'smooth'.
The only amphibians to bear claws are the African clawed frogs. Claws evolved separately in the amphibian and amniote (reptiliomorph) line. [12] However, the hairy frog has claw analogues on its feet; the frog intentionally dislocates the tips of its fingers to unsheathe the sharp points of its last phalanges.
The origin of the order name Anura—and its original spelling Anoures—is the Ancient Greek alpha privative prefix ἀν-(an-from ἀ-before a vowel) 'without', [6] and οὐρά (ourá) 'animal tail'.
