1. Amphiumas
Scientific name: Amphiuma spp.
Family: Amphiumidae
Continent: North America
IUCN conservation status: Refer to the accompanying text
Originating from the southeastern regions of the United States, amphiumas exist as elongated salamanders with rudimentary limbs. Preferring a carnivorous diet, they indulge in small aquatic organisms. The three amphiuma species are distinguished by the number of digits they possess, as their respective names imply.
2. Axolotl
Scientific name: Ambystoma mexicanum
Family: Ambystomatidae
Continent: North America (specifically, Mexico)
IUCN conservation status: Critically Endangered
Residing solely within the confines of Mexico, axolotls represent a unique kind of salamander, retaining their larval features throughout their lifespan—a phenomenon known as neoteny. While most amphibians undergo metamorphosis, venturing onto land as adults, axolotls remain aquatic. These carnivorous creatures partake in a diet consisting of diminutive aquatic organisms.
Astonishingly, if an axolotl happens to lose a limb, it possesses the remarkable ability to regenerate it—a process known as limb regeneration. These extraordinary amphibians are frequently sought after as pets despite being critically endangered in their natural habitat.
3. African Clawed Frog
Scientific name: Xenopus laevis
Family: Pipidae
Continent: Africa
IUCN conservation status: Least Concern
The African clawed frog boasts uniquely clawed hind feet and a flattened physique. Employing its claws to rend sustenance and ward off predators, this peculiar frog thrives exclusively in aquatic domains, subsisting on a varied menu of invertebrates and small fish.
4. Common Midwife Toad
Scientific name: Alytes obstetricans
Family: Alytidae
Continent: Europe
IUCN conservation status: Least Concern
Found scattered across Europe, these toads have become renowned for their extraordinary reproductive behavior, wherein the male assumes the responsibility of safeguarding the fertilized eggs wrapped around his hind legs. Nourishing themselves on insects and other minute invertebrates, they traverse their habitats.
5. Gardiner’s Seychelles Frog
Scientific name: Sechellophryne gardineri
Family: Sooglossidae
Continent: Africa (specifically, Seychelles)
IUCN conservation status: Endangered
Boasting a minuscule frame measuring a mere centimeter in length, this frog stands among the world’s tiniest amphibians. Endemic to Seychelles, an island nation ensconced within the Indian Ocean, it sustains itself by preying upon diminutive insects and other invertebrates.
6. Giant Salamanders
Scientific name: Andrias japonicus (Japanese Giant Salamander); Andrias davidianus (Chinese Giant Salamander)
Family: Cryptobranchidae
Continent: Asia
IUCN conservation status: Critically Endangered (Chinese) and Near Threatened (Japanese)
Marvel at the colossal giants of the amphibian realm, the world’s largest living amphibians, whose lengths can exceed a staggering 1.5 meters or 4.92 feet. These aquatic behemoths roam the waters, devouring fish, crustaceans, and other small aquatic creatures. Traditionally, two species have been recognized—the Japanese and Chinese giant salamanders. However, recent findings indicate the existence of at least two giant salamander species within China.
7. Hellbender
Scientific name: Cryptobranchus alleganiensis
Family: Cryptobranchidae
Continent: North America
IUCN conservation status: Vulnerable
Thriving within the eastern regions of the United States, the hellbender reigns as a substantial, fully aquatic salamander. Possessing a flattened physique, it sustains itself on crayfish, fish, and other aquatic denizens. Reaching lengths of up to 74 cm or 29 inches, the hellbender stands as the largest amphibian inhabitant of North America. Though equipped with lungs, it relies heavily on its extensively wrinkled skin to absorb the majority of its necessary oxygen.
8. Malagasy Rainbow Frog

The Mexican burrowing toad, a species proficient in the art of excavation, exhibits a specialized snout resembling a shovel, perfect for burrowing. Its proportions present a body nearly as wide as it is long. This peculiar amphibian predominantly feasts upon ants and termites. It is prevalent in Mexico and Central America.
10. Motorbike Frog
Scientific name: Litoria moorei
Family: Hylidae
Continent: Australia
IUCN conservation status: Least Concern
Hailing from the vast landscapes of Australia, the motorbike frog earns its name from the distinct call it emits, reminiscent of a revving motorcycle. Its habitat spans diverse environments, while its diet consists of insects and other minute invertebrates. Though classified within the “tree frog” family, Hylidae, the motorbike frog rarely strays far from the earth beneath.
11. Olm
Scientific name: Proteus anguinus
Family: Proteidae
Continent: Europe
