Almost all snakes reproduce sexually, with the participation of female and male. Only certain species are capable of parthenogenesis, i.e. the reproduction is not transmitted sexually, and from unfertilized eggs without the participation of a male. There among the snakes, as a rare exception, and true hermaphrodites, i.e. individuals who are simultaneously female and male. Such exceptional case was recorded on the small island of Queimada-Grande, South America. There were found the snake, dubbed the island bothrops, among which, in addition to ordinary females and males, meet bisexual individuals who make up the majority of the population. These individuals are females, while the ovaries are the male copulatory organs and Mature testes. Such individuals may in some cases play the role of females and to breed, and the males are fertilizing other females (ordinary or hermaphrodite). The existence in the population of the island bothrops such unusual females is so efficient, the need for normal males has dropped, and their share in recent years has declined.

So, a little about snakes.
More specifically misconceptions about them.
Well, the first misconception is prevalent everywhere: snakes slippery and cold.

You do not say that the book or, for example, the lighter is cold, when take it from the table? And the Boas and pythons has its own minimum thermoregulation, so they mostly maintain the temperature at several (up to 15) degrees above ambient. if you want, of course.
The second myth: snakes hypnotize their prey.
It is quite far from the truth, although if you watch hunting snakes, as it may seem. Explain the reason: snakes don’t blink and hunt (not all, but many, especially the big ones) from ambush. Because a snake sits motionless until the prey can’t get to the distance of the throw; the throw is so fast that it is not always possible to notice. Especially with the habit.
Another myth: the rattlesnake buzzes before the attack.
Not quite. Bursting when she’s scared and just wants to warn that moved away, after which, by the way, she will most likely crawl back home.
To depart, it is necessary slowly, avoiding sudden movements. Anyway, when dealing with snakes sudden movements inappropriate.
