So he casts out his giant penis like a fishing line to find a mate. And the barnacle needs it because he can't move around very easily. That's like a human's reaching the length of a bowling lane. That little crustacean has proportionally the longest penis of any animal on earth spanning up to 10 times his body size. Barnacleīut that's nothing compared to a barnacle's. If that's not impressive enough, his penis reaches nearly a quarter of his body length when erect. Hundreds of sperm glom together into bundles, which can swim faster than individual sperm, increasing their chance of fertilization. So during sex, the male alternates, swapping out spent pairs as each fires its semen. But that doesn't deter the males, because they have a 4-headed penis. Females have a forked reproductive tract. He'll line up with around nine other males and follow a single female for up to a month during mating season.
But his sex life is anything but ordinary. The short-beaked echidna survives mating. Short-beaked echidnaįortunately, not all males have it that rough. He loses his eyes, fins, and most internal organs, until, ultimately, he becomes just a portable sperm bank for the female. Instead of hunting for his own food, the male bites into the female, fusing his body with hers and living off the nutrients in her blood In return, he provides the one thing he has to offer: sperm.īut there's a catch. It would be like if a human male only came up to a woman's ankle. And you see that tiny parasite on her side? That's the male. Hey, at least it's a quick death, especially compared to some deep-sea anglerfish, like the triplewart seadevil. In the process, his semen shoots through her oviduct, where she stores it for later use. But sadly for him, he only gets to mate once because during the act, his reproductive organs are ripped off and his testicles explode. It turns out that for many species, sex kills. Scientists call this kamikaze mating technique "suicidal reproduction." Often times, he dies before his young are even born. That in turn crashes his immune system, making him extremely vulnerable to disease and infection. And all that testosterone revs up his stress hormone production into overdrive, crashing his immune system.
Brown antechinusįor two weeks every mating season, a male will mate as much as physically possible, sometimes having sex for up to 14 hours at a time, flitting from one female to the next. The average couple has sex for anywhere from 30 seconds to about 45 minutes. Now, 45 minutes sounds long, until you consider the brown antechinus.
