Which animal has no internal-organs, but reproductive ones?

For some, sex is just a mean to gain pleasure, for others a question of life and death. Mayflies belong to the latter. They have developed a very unique survival strategy. To reduce the risk of being eaten, they have a very short life span with a very goal-oriented lifestyle.

Mayflies are born exclusively to screw. In fact, while they enjoy a super-effective reproduction system, they can’t even feed, since their digestive systems are filled with air. 

So, to put it in Darwin’s terms – Mayflies are evolutionarily born to f*&ck.

Bonus facts: The current understanding is that many species that were once thought to be ”conservative” are actually promiscuous or opportunistic in nature. A wide range of species practice masturbates and use objects and tools to climax.

If you are really into animal sexual behavior, here are some more:  

Animal sexuality takes many different forms, even with respect to the same species. Among animals, researchers reflect on monogamy, promiscuity, genetic cross-species, sexual arousal between animals from objects or places, sex through coercion or coercion, copulation between dead animals, homosexuality in the animal kingdom, heterosexual behavior and bisexual, situational sexual behavior, and a wide range of other practices.

When animal sexuality is driven by the reproductive act, it is often referred to as mating or mating; for most nonhuman mammals, mating and mating occur at the heat point (the most fertile time of the female reproductive cycle), which increases the likelihood of successful impregnation. However, the study of animal sexuality (especially that of primates) is a rapidly developing field of study. While it was believed that only humans and a handful of other species performed sexual acts while others did it for reproduction and that animal sexuality was just an instinctive activity and a simple response to stimulation (sight, smell), The current understanding is that many species that were once considered monogamous are promiscuous or opportunistic in nature. A wide range of species emerges both to masturbate and to use objects as tools that help them to do so, in many species animals try to give and get sexual stimulation with others where reproduction is not the focus. This homosexual behavior has been observed in 1,500 species, of which 500 have been documented.

Animal sexual behavior has been a study of widespread controversy for many scholars. Females select males by assessing their physical ability, whether or not they are capable of providing protection. Fights between males of the same species are means by which females choose their partner or group leader to mate with the largest number of females, passing their genes onto their offspring.
