The etymological history of the term batrachian begins with the Greek word batrachos, which translates as “frog”. Batrachos led to batrácheios: what is typical of these animals. Then this concept arrived in scientific Latin as Batrachium and finally, in Spanish, it became batrachium.
A batrachian is an amphibian vertebrate animal that, at birth, is aquatic and breathes through gills, but then becomes terrestrial or semi-aquatic and begins to breathe through lungs. Another peculiarity of the batrachians, like frogs and toads, is that their temperature is variable.
According to DigoPaul, batrachians are also named anurans because they do not have a tail. Their body is wide and short, presenting their hind legs with great development that allows them to jump easily.
On the body of a frog, there is a wide mouth that may lack teeth, ears without external pinna, and eyes with lids. Although it is common to distinguish between frogs and toads, the distinction is not based on taxonomy. At a general level, frogs are those species with great ability to jump and swim and that have smooth skin. The toads, on the other hand, have a rougher skin and have less agility.
The feeding of the batrachians is usually based on terrestrial and aquatic vertebrate animals, although they can also ingest small invertebrates. Regarding reproduction, finally, these species deposit their eggs in packages or cords in the water.
In addition to everything indicated, we can establish a relevant series of data of interest or curiosities about the batrachians such as these:
-One of the most significant batrachians is the salamander.
-As a general rule, they are classified into two groups. On one side are the urodelos, such as the salamander or the newt, which have an elongated body, a long tail and four equal limbs. On the other hand, there are anurans, such as the aforementioned frogs and toads, which have a short and wide body as well as much longer rear limbs than the previous ones.
-Most batrachians, if not all, are determined to be oviparous, with the exception of the salamander which is ovoviviparous.
-It is considered that the batrachians were the first vertebrates to proceed to leave the water.
-The experts in this type of animals indicate that the most perfect eyes are those of the frog because they have enormous mobility and because they have two eyelids.
In the same way, we cannot ignore the existence of a music group that also goes by the name of Batracio. It originated in Seville and his compositions are a perfect mix between rock, ska, reggae and even funk. And it is defined as fusion.
In 2015 the formation of this band takes place, which has among its best-known songs some such as “La Charca”, “Pulgadas”, “No vuelvas” or “Yo no tonto tanto”.
