The middle ear consists of only the stapes bone and the oval window, which transfer vibrations into the inner ear through a reentrant fluid circuit as seen in some reptiles. Adults of species within the family Scolecomorphidae lack both a stapes and an oval window, making them the only known amphibians missing all the components of a middle ear ...
Amphibians are ectothermic, anamniotic, four-limbed vertebrate animals that constitute the class Amphibia. In its broadest sense, it is a paraphyletic group encompassing all tetrapods excluding the amniotes (tetrapods with an amniotic membrane , such as modern reptiles , birds and mammals ).
The largest living amphibian is the 1.8 m (5 ft 11 in) Chinese giant salamander (Andrias davidianus) [41] but this is a great deal smaller than the largest amphibian that ever existed—the extinct 9 m (30 ft) Prionosuchus, a crocodile-like temnospondyl dating to 270 million years ago from the middle Permian of Brazil.

The bishop-fish, a piscine humanoid reported in Poland in the 16th century. Aquatic humanoids appear in legend and fiction. [1] " Water-dwelling people with fully human, fish-tailed or other compound physiques feature in the mythologies and folklore of maritime, lacustrine and riverine societies across the planet."
All salamanders lack middle ear cavity, eardrum and eustachian tube, but have an opercularis system like frogs, and are still able to detect airborne sound. [ 22 ] [ 23 ] The opercularis system consists of two ossicles: the columella (equivalent to the stapes of higher vertebrates ) which is fused to the skull, and the operculum.
The Lissamphibia (from Greek λισσός (lissós, "smooth") + ἀμφίβια (amphíbia), meaning "smooth amphibians") is a group of tetrapods that includes all modern amphibians. Lissamphibians consist of three living groups: the Salientia ( frogs and their extinct relatives), the Caudata ( salamanders and their extinct relatives), and the ...
Living entombed animals are animals supposedly found alive after being encased in solid rock, coal, or wood for a long period of time. [1] The accounts usually involve frogs or toads. No physical evidence exists, and the phenomenon has been dismissed by science. [2]
