Yellow-headed side-necked turtle (confirmed introduction)
Yellow-headed side-necked turtle The appearance of the neck turtle is not eye-catching, because its carapace does not have many markings, but its head has very obvious bright yellow freckles. This is the most attractive feature, and therefore it is very popular among people.
1. Morphological characteristics of the yellow-headed side-neck turtle
This The base of the turtle is gray. The front sides of the hands and feet and the back of the head are slightly darker than the color on the carapace. There are some yellow freckles on the head, which is the reason for its common name. There are nine of them together - one on the top of the tip of the nose; one on each side of the head, below the nose spot; one directly below; one further back; one above; each There is another place on the opposite side of the eyes. All the images given to people are like a clown evil turtle smeared with oil paint.
The name unifilis comes from the fact that the turtle from the Orinoco basin has a single tentacle on its lower jaw (while the turtle from the Amazon basin has Two tentacles, this name is somewhat inappropriate). It is known that the carapace length of adult female turtles can reach more than 25 inches (63.5cm), while male turtles rarely reach half this length. The tail of the male turtle is much thicker and longer than that of the female turtle.
2. Separation of males and females
The merger of male and female in young turtles It's not easy to tell them apart, there's not much difference in their tails. As the female turtle grows, the yellow spots on her head will gradually fade and disappear, and the female turtle will often be much larger than the male. Males are smaller in size, and the yellow spots on their heads will always protect the bright yellow color and will not fade away. The male turtle's tail will gradually grow thicker, while the female turtle's tail will be shorter and shorter.
