On Earth, the population of living things is very large, but there are not many strange creatures, and most of them look exactly the same. Most of the strange species that appear are caused by genetic mutations, hybridization and other factors, so many people do not know much when they see these strange species.
According to a new report released by the Indian Forestry Agency, in just 3 months, India has found a rare golden "turtle" again, and many people see that this turtle may be like a lump of "gold", but it is not.
From the appearance, it is true that this turtle looks very strange, that is, we are talking about a strange species, it has a yellow shell, and the same is true for areas such as head and limbs, so it quickly became a hotly discussed species after being reported.
<h1 class="pgc-h-arrow-right" > several rare golden turtles have been found in 2020</h1>
Also in the second half of 2020, Nepal also discovered a "golden turtle", the unique color of the golden turtle is due to the extremely rare genetic mutation that changes its pigmentation. At the time, reptile scientist Kamar de Vocotta said that this was only the fifth golden turtle found in the world, so it was quite rare, belonging to the North Indian box turtle, the first case in Nepal. There is a saying here that the North Indian box turtle is a genus of fish turtles, and their habits are the same as those of turtles.
It is an oviparous amphibian reptile, a delicacy on the table, of course, this "golden turtle" belongs to genetic mutations brought about, so let's just take a look. And this time it was found not in Nepal, but in India. Although this chromatic aberration is rare in nature, this strange phenomenon may be more common in India than many people recognize. That is to say, it is easier to find the existence of this "golden turtle", this is also the second discovery in India in 3 months, so the relative population is expanding.
< h1 class= "pgc-h-arrow-right" > the general growth of "golden turtles" in South Asia</h1>
Judging from the existing discoveries, it is true that the "golden turtles" in South Asia are growing, and the probability of discovery is also increasing.
Over the years, it is not the first time that the "golden turtle" has been reported in South Asia, and there are many mutant species found in India, in itself, the color of this "golden turtle" belongs to the brown, with yellow spots and white milky bottom surface, and in various regions of South Asia, this is the most common aquatic turtle species, so genetically abnormal turtles do not occur very often.
But as soon as it appears, it's easy to see it among most of the turtles. As early as 1997, one was found in Gujarat on the west coast of India, and it is said that Myanmar and Bangladesh have also found similar examples, but there is no specific amount of data disclosed, so there is no way to say how many species there are.
We say that this is a genetic mutation, but in fact we can simply understand it as a situation similar to "bioalblification", which is a genetic variant that causes a complete lack of pigment in the body, and in some cases, the yellow pteridine pigment can survive, dominating in color production (along with eye pigment), rather than appearing completely white.
So eventually led to the emergence of the "golden turtle", Indian herpetologists said that not only there are "golden turtles", if under special circumstances, the species will even appear red, that is, become a "red turtle", so it is relatively rare, this is the case of the creature. Let's talk about a peculiar situation about turtles.
<h1 class= "pgc-h-arrow-right" > "extinct" centennial turtles reappear</h1>
In everyone's mind, it would not have been possible if the organism had gone extinct, but there is indeed a turtle that appeared a hundred years after its disappearance, and this turtle is the "Galapagos tortoise on Fernandina Island".
According to scientific reports, the Galapagos tortoises on Fernandina Island, which live in the volcanic island area, have disappeared as early as a hundred years ago (a century ago), because living in the extreme conditions of the volcanic island area, it is unlikely to survive, so it was once considered extinct.
But this situation is not as simple as everyone thinks, that is, in recent years, scientists have unexpectedly discovered the existence of Galapagos tortoises on Fernandina Island, although only one has been found, but enough to live The species is not extinct, and it exists.
So once again subverting our understanding of the "viability" of life, not all species are so easy to disappear or extinct, only because of some situation and survive.
Of course, how the Galapagos tortoise on Fernandina Island survives, scientists do not clearly explain, do not know where it is, the emergence of this Fernandina Island Galapagos tortoise also brings hope to the species group, the use of artificial breeding may eventually expand this biological population, to avoid its extinction, but now it is just such a one, natural pairing is impossible, it depends on whether there are other ways to expand, this is what we are looking forward to, We also hope that the Galapagos tortoises on Fernandina island will continue to spread.
