We only know of a 'twerking queen' Miley Cyrus (twerking means sexy dance), it turns out that not only this fiery girl knows tewrking but the male 'black widow' spider also uses this dance. In a very special way.

The black widow spider is much larger in size than the male

The entomologist Samantha Vibert pointed out: 'When you reach the spider's spider web, the male will vibrate up and down while the rest of the body is immobile.' The 'black widow' spider is a notorious voracious, almost everything that falls into its ambush becomes a delicious meal. Therefore, the male dance is intended to convey an urgent message to the children 'Please don't eat me, I'm here to mate'.

Spiders are a blind species, they have no eyes, their most important senses are based on vibrations in their webs from which to identify the location of the prey. So, in a very specific way, male spiders have a way of announcing through spiderweb vibration so as not to be mistaken for some poor prey.

Even snakes become prey of the black widow spider

In the laboratory, scientists studied the vibrations of a male 'black widow' spider, a male male spider and some other spiders. The results show that the vibrations that pass on the spider's web are different, the 'black widow' will recognize each other in a different vibration without confusion.

The vibrations of black 'widows' males sent to their 'black widows' are simply a message to help their children become more gentle. However, when scientists increase the vibrational sound volume of the male, the female will immediately become aggressive and rush to attack the male.

This explains why male spiders are trying to keep their 'sexy' dance at a moderate level to avoid activating their predatory instincts. Even stopping dancing is a wiser way to help males preserve their lives.

The true situation of the 'black widow' spider is a death game.
