Telmatobius Atacamensis
''Telmatobius atacamensis'', commonly known as the Atacama water frog, is an aquatic frog species of the family Telmatobiidae. It is endemic to the Puna region of Salta, Argentina, where it inhabits high-altitude streams and wetlands. Due to its restricted range and specialized habitat, ''T. atacamensis'' faces significant conservation threats, including habitat degradation, chytridiomycosis, and invasive species. Habitat and Distribution ''Telmatobius atacamensis'' is a strictly aquatic species, inhabiting mountain rivers, streams, and wetlands in the high-altitude environments of northwestern Argentina. Although the ''Telmatobius'' genus is widely distributed from Ecuador to Chile and Argentina, ''T. atacamensis'' is one of only three out of fourteen ''Telmatobius'' species in Argentina that are microendemic to the Puna region of Salta. Its known range is less than 20,000 km², primarily within the San Antonio de los Cobres area and Los Patos River. The Puna region ...

Aquatic Locomotion
Aquatic locomotion or swimming is biologically propulsion , propelled motion through a liquid medium. The simplest propulsive systems are composed of cilia and flagella. Swimming has evolved a number of times in a range of organisms including arthropods, fish, molluscs, amphibians, reptiles, birds, and mammals. Evolution of swimming Swimming evolved a number of times in unrelated lineages. Supposed jellyfish fossils occur in the Ediacaran, but the first free-swimming animals appear in the Early to Middle Cambrian. These are mostly related to the arthropods, and include the Anomalocarididae , Anomalocaridids, which swam by means of lateral lobes in a fashion reminiscent of today's cuttlefish. Cephalopods joined the ranks of the active swimmers (nekton) in the late Cambrian, and chordates were probably swimming from the Early Cambrian. Many terrestrial animals retain some capacity to swim, however some have returned to the water and developed the capacities for aquatic locomotio ...

Microendemic
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becoming ...
