[Curiosities] Salamander curiosities that will surprise you

[#Wittels-]

The salamander is a urodel amphibian capable of adapting to the aquatic and terrestrial environment. Around the world there are around 550 different species. Their diet is based on the intake of insects and small crustaceans. It should be noted that in their natural and wild state they have a life expectancy of twenty years. Here we tell you the most interesting curiosities of the salamander.

origins
This animal has been on planet Earth for at least 230 million years. In 2020, the oldest salamander fossil ever found was discovered in Kyrgyzstan.

Species
There is a po[CENSORED]r belief that the salamander is a small animal, but this is not the case in all cases. There are very large species that measure more than a meter. This is the case of the Japanese giant salamander, which is currently in danger of extinction.

ways to breathe

 

In general, amphibians are characterized by having gills in their early stages of life and lungs once they reach adulthood. However, the salamander does not follow this rule. Some species only have gills and never develop lungs. Depending on the species, there are three forms of respiration: through the lungs, through the gills or through the skin.

fertilization
The frog and the toad present an external fertilization. But 90% of salamander species have internal fertilization. The males deposit bags of sperm on the ground, which the females then take to fertilize themselves. Once they have taken them, they can retain them inside their body for up to a year and a half.

vocal chords
The salamander does not have vocal cords. Makes clicking noises when threatened. With the other specimens of its species, it communicates through chemical signals and touch.

regeneration
One of the great curiosities of the salamander is that it can regenerate its limbs, and the speed at which it does so basically depends on its age. In addition to limbs, he also has the ability to replace damaged parts of his lungs, heart, and brain.

 

temperatures
Something that very few people know about the salamander is that it is very resistant to low temperatures. Some species enter a dormant state similar to hibernation to survive the cold winter. The Siberian salamander can even handle being frozen for a while, as it generates a kind of "antifreeze" to protect its internal organs. Therefore, even if his body is frozen, he can stabilize alive.
