The head is pointed, and the snout is somewhat depressed in two species. . Amphiuma cells, especially the red blood cells, are the largest known in vertebrates, and they have long been used in physiological studies and in the classroom.

Amphiuma cells, especially the red blood cells, are the largest known in vertebrates, and they have long been used in physiological studies and in the classroom. Structure of the teeth within the jaw tend to be arched caudal on the head. [16] This buccal/nares component to the amphiuma respiratory process supplements the contribution performed by the lung. The species has a narrow range in the coastal plain of southeastern Mississippi through the Florida panhandle and the northern part of the Florida peninsula to the extreme southern portion of Georgia in the United States. [13] These two feeding habits give the amphiuma the ability to have a larger variety of food (live or dead). The salamanders are strictly carnivorous and eat worms, aquatic insects and aquatic insect larvae, frogs, salamanders, fishes, and any other small vertebrates. [20][21] There has been, however, no other physical indicating factors for male-male combat as in other species of amphibians, such as horns or spines. The scientific name of this frog is ranitomeya reticulate. [20] Generally, males have been found to possess larger bodies and longer heads compared to the female sex, which normally is indicative of male-male combat observed within the population. The male courts the female by rubbing his snout against her. Amphiuma pholeter Neill, 1964, 4.5 mi (7.2 km) east-northeast of Rosewood, Levy County, Florida, United States. The female coils around and guards the eggs. Collecting also may be a detriment to the species. It has been documented that amphiuma will pass on smaller crawfish in order to consume larger ones. There are 2 other species in the genus. If a ditch or pond goes dry, amphiumids hide in holes where they can estivate; they have been excavated from as deep as 3.3 ft (1 m). [16][17] Their lungs are long organs, extending over half of the body length, with dense capillary networks and large surface area that suggest the utilization of the entire lung for respiration while the animal is in water or on land. Amphiumas are elongate, cylindrical, eel-like salamanders with four small limbs that are usually less than 0.4 in (1 cm) long. Courtship apparently takes place in winter or spring, and the eggs are probably laid in June and July, with hatching in late summer or early fall. Amphiumas may be sexed as male or female based on the pigmentation of the cloacal opening. Amphiuma flesh is edible and tastes much like frogs' legs. They may lie in wait for passing prey or prowl in search of prey. [17], Amphiuma demonstrate sexual dimorphism in relation to the size of their bodies and the size of their heads. This species has three toes on each foot. Locomotion is via lateral undulations. Other species of skinks The bite of amphiumas is considered to be poisonous by some rural inhabitants. . A. tridactylum probably reach maturity in three to four years. In addition to eating frogs, snakes, fish, crustaceans, insects, and other amphiuma, amphiuma have been found to eat annelids, vegetables, arachnids, mollusca, and larvae. [7] Amphiumas also have a lateral line visible on the sides of their bodies, which are capable of detecting movement and are used in aid of hunting. Egg development in female Amphiuma tridactylum occurs from November to September and spermiogenesis in the male from August to May. Presumably, the diet is like that of other amphiumas, but its small size apparently limits its diet to small clams, earthworms, larval aquatic insects, and small beetles. Despite this possible relationship, the two families must have still diverged very early on. [21] Some populations do not show these sexual dimorphic traits, and in certain locations female and male bodies do not exhibit any traits with significant differences.[22]. Petranka, J. W. Salamanders of the United States and Canada. Concise phylogenetic placement of the family has not been possible, despite various external and internal structural features, specific muscles present or absent, chromosome numbers and appearance, and biochemical studies.
