These marine mammals may also migrate due to the fact that their food supply may migrate away from some of the colder environments causing their prey to become scarce and limited during the winter. If that's the case, it also makes sense that they choose to discard their penises, just like a doctor would if they had a dirty syringe.When it comes to the various types of seasons for marine mammals such as whales their seasonsВ can be broken down into two primary seasons known as mating season and feeding season.Дepending on theВ species of whale and where they live their mating seasonВ can vary,В but itВ typically occurs during the colder fall andВ winter months where whales canВ take advantage of the warmer tropical climates near the equator. Researchers speculate that the penile spines are there to remove any rival sperm from another male. It's also important to note that these tiny sea creatures are hermaphrodites, meaning that while mating, both of the partners will give and receive sperm. Scientists are unsure whether these tiny creatures can regenerate their penis once their sex life comes to a halt or if it is a one-and-done ordeal.

The good thing is, even once they're done using their penis, they have two more disposable penis segments hidden beneath the surface of their skin. This single-use penis will extend just 1 centimeter out of the slug's body, even though it is three centimeters long.

The Chromodoris Reticulata, one species of sea slug, has a spined penis that can only be used once in its lifetime. When it comes to defecation and urination, this animal uses a cloaca, a small opening on its body. One thing separating Echnida's penile functionality from other terrestrial mammalian males is that its penis is solely used to mate. However, when it needs to be put to use, it will come out of its prenuptial sac. When the echidna isn't getting its jollies, its penis stays flaccid inside the body. The spines trigger ovulation to increase the fertilization success rate. Plus, similar to the rest of the echidna, its penis has a spiky coat made of sharp penile spines. One look at the female two-branch reproductive system, and this two-headed penis entrance begins to make a lot more sense. Because cetaceans never find themselves in ambient temperatures, they've found unique ways to compensate.Д«lue whales have blood in their veins that they send directly to their testicles, warming up their sperm and helping it to remain viable for use. A regular scrotum will lower when it reaches the ambient temperature to help keep its sperm viable. It's also worth noting that blue whales and other cetaceans do not have scrotums like most terrestrial mammalian males.

When having intercourse with female blue whales, they can ejaculate multiple gallons of sperm. Each blue whale testicle can weigh up to 150 pounds, about the same weight as the average adult male human. The largest penis in the animal kingdom can easily weigh a couple hundred pounds, but the largest blue whale penis ever recorded weighed 800 - 900 pounds!ДЇUN FACT: The largest penis of any adult land animal goes to the adult elephant, which can surprisingly grow up to six feet long on average.Д«ecause they're the biggest whales in the world, it's no surprise that they've got giant testicles.
