Researchers found that 89% of male spider crook" Bissoura Mirabliss " used this strategy has been able to mating, compared with 40% of males that do not use this method. noted Dr. Trine بيلده specialized in biology at the University of Aarhus, that this strategy were not well known among animal until now, only to evade predators , and this is the first time that discovers scientists where some animals use this method for mating. confirmed scientists that males that تحتال Ali Onthaha fabricating death pollinate a larger number of eggs a female because a mating be longer. spiders maintains genealogical In the same regard, the researchers reported Male spider Germans during practice with the female mating process leaves a part of it inside in order to cut off the road on the other male competitors and ensures the existence of a pure strain of hard not to mix "lineages" of others. study showed that this phenomenon is another dimension, is the keenness Spider-mentioned process terminates quickly because it is known that the female if they were larger than the male kill him, and after that performs duties marital them.

For his part, Bob Hiotr Director of the Research Center sharks in Florida, that this phenomenon abound among all vertebrates except mammals, they are found among birds, amphibians, fish, and now exist between the sharks. mention that the process of reproduction Allatzaugeh abound among which is rare among insects, birds and amphibians.
