Think Miley Cyrus, but with a few more legs: Simon Fraser University researchers have observed that male black widow spiders shake their abdomens in a "twerking" shimmy to create vibrations so that females do not confuse them for prey. Cannibalism is a common danger facing male spiders attempting to approach females, since most spiders are predatory and extremely aggressive. Male black widow spiders, like the one on the right, shake their abdomens to produce distinct vibrations to indicate they are a potential mate, and not dinner. Two of Gries' graduate students, Samantha Vibert and Catherine Scott, set out to determine how male black widows approach females on the web without being mistaken for prey. The researchers used sophisticated equipment to measure the vibrations produced by males approaching females on a web and then compared those to the vibrations from house flies and crickets. While the short, percussive vibrations of the flies and crickets triggered a predatory response from the female black widows, the male spiders' distinct whispers did not.
Gries said the male spider has a delicate task: get the female's attention without provoking an attack.
Female black widows, as their name suggests, have a reputation in pop culture for eating male spiders after they're finished mating. The vibrations are in addition to other strategies male spiders use to protect themselves from aggressive females, including cutting the threads of the females' web to limit her movement or attempting to mate with a moulting female.
This is one of the most interesting facts that Camel Spiders appears to have ten legs and are mainly found on the back of the camel stomach (so called camel spiders) and are 1 ft.


This is one of the interesting facts that the Black widows eat the male during mating which is a myth as it is not entirely true. In contrast, house flies and crickets produce short, high-pitched vibrations, which signal to the female spider (on the left) that food is waiting.

They believe that they are harmful pertaining to the human life but in real these are not the fact, rather they are myths. Black widow is called so because during mating a female spider kills her husband and thus become a widow. This myth was stated by Lisa Holtz, but because this is a myth then no need of worrying about it by preventing your mouth with tapes during sleeping which some people did earlier. An email arrived on net describing that a person was bitten by a scorpion and after few hours swelling arises which one day burst out and give rise to a baby spider. This is a total myth because firstly they are not the spiders, rather they mainly belong to the class of Solifuage which include other spiders also like wind spider and sun spider. This is a myth because though these spiders can bite but they have no poison and venom and have harmless bites. This fact is mainly found among the southern black widow spider and they prevent their nest more aggressively than other black widow female spiders.


But at one instance, this myth turned out to be fact that when you are away from your home for a month and then check your home thereafter, you will find many spiders clinging at the corner of the walls. Another myth related to them is that they run with a speed of 25 mph and during running they make some screaming noise. These spiders should not be confused with the Opiliones or crane fly as they are not spiders as they don’t have venom.
After laying more than hundred eggs during mating, maximum 30 of them became the black widow female spiders. This is a myth story which is well related to the story of bot fly which describes that a bot fly lay eggs on human skin. Though Camel spiders are nocturnal therefore they stay active mainly in nights and run away from the heat generated by sun. The legs of these spiders are so long that they easily catch the mosquitoes and other web spiders in their own web and kill them.
