Biofluorescence in a three-toed amphiuma. The three-toed amphiuma looks rather eel-like, with an elongate, dark gray-black, or brown colored body, and tiny vestigial legs. A large salamander, one record sized individual was recorded at 41.25 inches (104.8 cm), but 18–30 inches (46–76 cm) is the typical size of an average adult. [3]
Amphiuma is a genus of aquatic salamanders from the United States, [2] the only extant genus within the family Amphiumidae / æ m f ɪ ˈ juː m ɪ d iː /. [3] They are colloquially known as amphiumas . [ 2 ]
The two-toed amphiuma (Amphiuma means) is an aquatic salamander widely distributed in the southeastern United States. It is commonly, but incorrectly, called "congo snake", " conger eel " or the "blind eel".
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 ).
Dissorophoidea is a clade of medium-sized, temnospondyl amphibians that appeared during the Moscovian in Euramerica, and continued through to the Late Permian and the Early Triassic of Gondwana. They are distinguished by various details of the skull, [2] and many species seem to have been well adapted for life on land.
Greater siren out of water. Greater sirens are carnivorous and prey upon invertebrates (such as insects, crustaceans, gastropods, bivalves, spiders, molluscs, and crayfish) [11] and aquatic vertebrates (such as small fish) [11] with a possible preference for molluscs (such as snails and freshwater clams), [8] [12] although they have been observed to eat vegetation such as algae.
Euskelia is a proposed clade of extinct temnospondyl amphibians. The naming derives from the ancient Greek eu, meaning "true", and skelos, meaning "limb", in reference to well-ossified limb bones with crests to which muscles were attached. [1] Members of this group have the most ossified skeleton of all temnospondyls. [2]
The human skull is the bone structure that forms the head in the human skeleton. It supports the structures of the face and forms a cavity for the brain. Like the skulls of other vertebrates, it protects the brain from injury. [6] The skull consists of three parts, of different embryological origin—the neurocranium, the sutures, and the ...
