1, the residual hind limbs can be seen, and the male is much more significant than the female. Generally speaking, male snakes are small, well-proportioned and dark in color; Female snake: she is big, obviously with a big belly and two small heads, and her body color is light.
2, look at the body color. Most female snakes are brightly colored and feel softer when touched by hand. The male snake's body color is slightly worse than that of the female snake, and he is fierce and irritable. The mother snake is more docile.
3. Look at the head. The female snake's head is mostly oval, and the male snake will be obviously triangular when angry.
4. See if there is a connector. Most of the tails of female snakes suddenly taper down from the back of anus, while that of male snakes is the opposite. Because the male snake hides a pair of connectors (snake whips) 2.5 cm down the anus, the tail of the male snake is thicker than that of the female snake.
The most reliable way to distinguish a male snake from a female snake is to turn the snake upside down, put the snake's back on a flat surface (harder), and then press it with your hand behind the snake's anus and push it forward from the tip of the tail with a little force. If the genitals are everted, it means the male is the female.
