Planet Earth is home to a large number of rare animal species and many of them are amphibians.
These amphibians could easily be classified as very strange animals before our eyes. They are totally different from the species we are used to seeing on a daily basis.
Without a doubt, within the animal kingdom amphibians are a curious class of animals that, if we base ourselves on the evolutionary process, are halfway there, a condition that makes them more susceptible to being in the category of rare.
If you want to know what animals make up our top 7 rare amphibians, read on.
The 7 rarest Amphibians in the world
1. Axolotl (Ambystoma mexicanum)
The Axolotl is a rare amphibian whose discovery dates back more than 150 years.
This animal is part of this small list because of its amazing ability to regenerate its limbs, organs and tissues in a short time and without leaving any after-effects.
Besides, it keeps its strange larval appearance during its whole life and has gills in the shape of a feather that stick out from its body.
2. Olm (Proteus anguinus)
The Olm is another of the rarest amphibians in the world because it is a transparent skinned and completely blind aquatic creature.
This animal is known to live underground and be able to go up to ten years without feeding, however, when it needs to perform this task it usually catches its victims using electrosensitivity and smell.
3. Chinese Giant Salamander (Andrias Davidianus)
The Chinese Giant Salamander holds the title of the world’s largest amphibian and at the same time one of the strangest.
One feature that makes it so rare and special at the same time is the way it breathes. The Giant Chinese Salamander lacks guts, so it sucks in oxygen through its porous skin.
4. Darwin’s Frog (Rhinoderma darwinii)
The Darwin’s frog ranks fourth on the list of the world’s rarest amphibians.
The reason? its unusual coloration that allows it to blend in with the vegetation and persuade potential predators to take advantage of its small size.
5. Purple Frog (Nasikabatrachus sahyadrensis)
The next amphibian on the list is the Purple Frog, an animal with a totally unique appearance, discovered a few years ago in the mountainous depths of India.
This bright purple yearling has a robust, oval body, with a small pig’s muzzle, short, thick legs and a small head for the exaggerated size of its body.
6. Lungless Salamanders
The Lungless Salamander is a rare animal found especially on the American continent.
Interestingly, this salamander uses its strange skin to breathe through its oral mucous membranes.
Despite the curious fact that this animal is currently in danger of extinction.
7. Ghost Frog (Sphaenorhynchus lacteus)
The Ghost Frog usually lives in humid forests, creeks and rivers, so thanks to this condition it has developed excellent swimming skills, being of great help in this task the patting of its small legs.
This amphibian of the family Heleophrynidae is called Ghost Frog because of the extreme complexity of encountering or observing it.
Characteristics of the Rarest Amphibians
Rare amphibians have various characteristics that differentiate them from one another, and one of these is their skin, as some have completely smooth skin, while others have small bumps.
These animals are characterized by a transition from the larval to the adult state. They begin by breathing through gills, but when they reach an adult stage they breathe through their lungs.
However, there are cases of species such as the Giant Chinese Salamander or the Lungsless Salamander, which breathe through their skin.
Other species, including the axolotl, retain their larval appearance throughout their lives, giving the impression that they have not finished developing.
These species are not capable of regulating their body temperature, so they depend on the temperature of the environment around them.
On the other hand, the pigmentation of these rare amphibians varies greatly, some being transparent, others using their color to camouflage themselves and avoid being prey to predators, this being the case of Darwin’s Frog.
Habitat of rare species
These rare amphibians can be found living in various environments around the world, both on land and in aquatic environments.
Despite this, amphibians are not able to live in areas with low temperatures, due to their inability to regulate their body temperature.
What do amphibians feed on?
The diet of these rare amphibians varies as they get older.
In their larval stage, their diet is based solely on vegetables, and as they grow and develop, their diet becomes comprised of small animals.
The reproduction of the Strange Amphibians
Most of the rare amphibians have an oviparous reproduction mode, having clear that their fertilization can be internal or external depending on the species.
An important feature to highlight during this stage is that some males emit sounds to attract the attention of the female.
After mating, the young usually go through three different stages: a larval stage, metamorphosis and finally the arrival of adulthood.
