The Rio Grande Silvery Minnow is a “small herbivorous North American fish” with “small eyes and mouth”. The diet of the fish is believed to consist of “river plants and benthic macroinvertebrates”, which consists of “small living animals among stones, logs, sediment, and aquatic plants on the bottom of rivers and lakes.” Due to the small size of the fish and difficulty accessing their stomachs, there is “little research into their diet”.…
The White-Nosed Coati (Nausa Narica) belongs to the Procyonidae family and is a relative of the raccoon. The most prominent feature that distinguishes Nausa Narica is it’s long tail, which extends to about 50 cm in length, and accounts for approximately half of its total body span. The white-nosed coati inhabits dry and moist forests all throughout South America where climbing trees are an important aspect of their day-to-day life. The main predators of the white-nosed coati, boas and hunting cats and birds of prey, are also adapted to arboreal life making efficient climbing and balance while climbing crucial for the coatis survival. The length of their tail thus presents itself as an acquired trait that enables them to maintain balance as they climb trees in addition to its uses in the social organization of the species. As Hass and Valenzuela (2002) observed in Nausa narica their tail has uses in the social organization within a population against the threat of predators. The length of their tail allows them to be seen over tall grasses and vegetation when on the ground, enabling them to communicate with each other as well as communicate to the predator that they have been identified as a potential threat. It has not yet been established whether the white-nosed coati would have the same survival and reproductive success in their environment with their existing predators if their tails were shorter in length resembling that of its close relative the raccoon, although it seems plausible. The length of the white-nosed coatis (Nausa narica) tail is an adaptation in response to the external threat of predators that affects their survival within their environment.…
A head that looks like a hammer, one eye and nostril are located on each side of the head, extra-tall dorsal fins. They grow to about 3 feet (0.9 meters) to 20 feet (6.1 meters). They weigh to about 230-450 kg (500-1000 lbs). They are usually grey, brown, or white. They have smooth skin.…

Blindness in the Mexican tetra fish is a controversy among scientists whom have long-debated the mechanism of this evolutionary change. The Mexican tetra fish, Astyanax mexicanus, exists in two morphs: a sighted surface form and a blind cavefish form. The debate amongst scientists is rooted in the process by which the Mexican tetra became blind. Evolution demands progress, yet the blind Mexican tetra suggests regression, as it lost its vision over time.…
They usually compete with several different birds, including the Great Horned Owl for nesting sites. They are carnivorous. Diet is composed of small mammals such as rabbits and rodents. It will also prey on snakes, lizards, birds, and fish. It is an opportunistic feeder and feed on whatever is available. It usually hunts from an elevated perch.…

The Appalachian Elktoe is a small freshwater animal that reside in Eastern Tennessee and Western, North Carolina. It has a thin familiar shell, extending to about 4 to 5” inches in length. To the common untrained eye, it looks like any other mussel. The adult mussels are usually dark brown to greenish-black. They have the appearance of a lob-sided flying saucer with striated lines. Further, “ The shell nacre (inside shell surface) is shiny, often white to bluish-white, changing to a salmon, pinkish, or brownish color in the central and beak cavity portions of the shell; some specimens may be marked with irregular brownish blotches”[2] . The reproductive cycle of the species is similar to other native mussels. Historically, the species has been recorded from the Tululu Creek (Tennessee River Drainage, the main stem of the French Broad River, and the Swannanoa River (French Broad River” (Clarke 1981). The elktoe mussel requires a specific habitat in order to maintain a healthy population. The components of habitat that the elktoe requires respectively a specific depth, a specific flow of water, and a specific mix of bottom composition. The elktoe is known to live in the “riffle sections” [3]of small to medium sized streams with gravel and sand bottoms.…

The axolotl is an amphibian that is found in complex of lakes, close to Mexico City in south-central Mexico. These peculiar creatures are carnivorous animals, and they have a pure meat- based diet. They also eat worms and insect larvae that develops under the surface of the water, along with molluscs. An axolotl is found in an albino and live a great deal of their lives hiding under rocks and in crevices. Most axolotl are white or pink in color, but they can also be black, grey, and brown. They also have feathery gill and flattened-shaped head, with permeable skin. Like salamanders and newts, axolotls are able to regenerate limbs that have been damaged or detached. These creatures are critically endangered due to levels of pollution nearby…
