However, many amphibian declines or extinctions have occurred in pristine habitats where the above effects are not likely to occur. The causes of these declines are complex, but many can be attributed to emerging diseases, climate change, increased ultraviolet-B radiation, or long-distance transmission of chemical contaminants by wind.
This is a List of amphibians of the Democratic Republic of the Congo by family.It lists all families and species of amphibians in the Democratic Republic of the Congo.. The list below follows Frost, 2011: Amphibian Species of the World, an Online Reference.
Most amphibian species are also threatened by native habitat loss, [41] and some species are now only breeding in modified habitat. [42] Endemic organisms with limited ranges are most affected by habitat destruction, mainly because these organisms are not found anywhere else in the world, and thus have less chance of recovering.
Chytridiomycosis has been linked to dramatic population declines or extinctions of amphibian species in western North America, Central America, South America, eastern Australia, east Africa , [1] and Dominica and Montserrat in the Caribbean. Much of the New World is also at risk of the disease arriving within the coming years. [2]
The population of the mountain chicken frog, once abundant in the Caribbean, has dropped by over 99% in 20 years due to a deadly fungal disease.

However, the zoospores are capable of chemotaxis, and can move towards a variety of molecules that are present on the amphibian surface, such as sugars, proteins and amino acids. [9] B. dendrobatidis also contains a variety of proteolytic enzymes and esterases that help it digest amphibian cells and use amphibian skin as a nutrient source. [10]
The film refers to the Baiji and the Hawaiʻi ʻōʻō as recent examples of extinction (although both of these species are still believed by some to be extant), and identifies the Amphibian extinction crisis, the overfishing of sharks for shark fin soup and as bycatch, among others, as current causes for concern.
