Amphibian - A cold-blooded, smooth-skinned vertebrate of the class Amphibia, such as a frog or salamander, that characteristically hatches as an aquatic larva with gills. The larva then transforms into an adult having air-breathing lungs.
Vertebrate - A member of the subphylum Vertebrata, a primary division of the phylum Chordata that includes the fishes, amphibians, reptiles, birds, and mammals, all of which are characterized by a segmented spinal column and a distinct well-differentiated head.
Pollutant - Any substance, as certain chemicals or waste products, that renders the air, soil, water, or other natural resource harmful or unsuitable for a specific purpose.
Environment – The aggregate of surrounding things, conditions, or influences; surroundings; milieu.
Extinction - The act or process of becoming extinct; a coming to an end or dying out: the extinction of a species.
Biodiversity - Diversity among and within plant and animal species in an environment.
Cold-blooded - Designating or pertaining to animals, as fishes and reptiles, whose blood temperature ranges from the freezing point upward, in accordance with the temperature of the surrounding medium; poikilothermal.
Population - The total number of organisms inhabiting a country, city, or any district or area.
Endangered - Threatened with extinction
Chytridiomycosis - Any of the simple, algaelike fungi constituting the class Chytridiomycetes, order Chytridiales, of aquatic and soil environments, having flagellated zoospores and little or no mycelium.
Concoction - To prepare by mixing different components.
Alkaloids - Any of various organic compounds normally with basic chemical properties and usually containing at least one nitrogen atom in a heterocyclic ring, occurring chiefly in many vascular plants and some fungi. Many alkaloids, such as nicotine, quinine, cocaine, and morphine, are known for their poisonous or medicinal attributes.
Antibiotics - A substance, such as penicillin, that is capable of destroying or weakening certain microorganisms, especially bacteria or fungi, that cause infections or infectious diseases. Antibiotics are usually produced by or synthesized from other microorganisms, such as molds. They inhibit pathogens by interfering with essential intracellular processes, including the synthesis of bacterial proteins. Antibiotics do not kill viruses and are not effective in treating viral infections.
Enzymes - Any of numerous proteins or conjugated proteins produced by living organisms and functioning as biochemical catalysts.
Tumour - An uncontrolled, abnormal, circumscribed growth of cells in any animal or plant tissue.
Hormones - A chemical substance secreted by an endocrine gland or group of endocrine cells that acts to control or regulate specific physiological processes, including growth, metabolism, and reproduction. Most hormones are secreted by endocrine cells in one part of the body and then transported by the blood to their target site of action in another part, though some hormones act only in the region in which they are secreted. Many of the principal hormones of vertebrates, such as growth hormone and thyrotropin, are secreted by the pituitary gland, which is in turn regulated by neurohormone secretions of the hypothalamus. Hormones also include the endorphins, androgens, and estrogens.
Cryopreservation - To maintain the viability of (cells, tissue, organs, etc.) by storing them at very low temperatures.
Regenerate - To re-create, reconstitute, or make over, esp. in a better form or condition.
Synthetic - noting or pertaining to compounds formed through a chemical process by human agency, as opposed to those of natural origin.
Habitat – A natural environment where an organism lives.
