A yellow-bellied watersnake gave birth for the second time in it's life without genetic contribution of a male in a rare process known as asexual reproduction.
Female butterflies choose their mates based on smell. However, some male hairstreak butterflies have evolved without scent-producing organs, which puts them at a disadvantage.
Birds that are able to mate with their "true love" have a higher rate of reproduction success and are more committed to their offspring, according to researchers from the Max Planck Institute for Ornithology.
Researchers discovered that male seahorses can be just as nurturing during their pregnancy as female mammals.
A recent study observed the reproduction success of male orangutans. They found that females are more attracted to males with padded cheeks.
It seems that males may not be necessary for reproduction after all. Scientists have discovered that around three percent of smalltooth sawfish living in a Florida estuary are the product of "virgin births" - the first case ever seen in vertebrates in the wild.
Here's something you probably didn't know. Sharks, skates, and rays - everyday Chondrichthyes - boast some very strange sexual organs. Like a pair of clasper-like penises, the male sex organs of a shark literally hook inside a female shark's cloaca in a unique reproductive strategy. Now, researchers think they have finally determined how these animals developed such strange members.
When you hear "getting it on like animals" you probably think animals are 'doing the deed' all the time and whenever they please. But when you really think about it, how could they? With predators always looking to make an easy meal of any pair that's... distracted, it may be hard to get some alone time. That's why one frog in Brazil builds secret underwater chambers just for this purpose.
The big red bottom of female baboons has always been an iconic image for the species. However, even if they knew the lyrics, no male baboon would ever be caught enthusiastically singing "Baby Got Back." New research has revealed that baboons don't actually care what sized backside "baby" has at all - a huge surprise for animal behaviorists everywhere.
Scientists have discovered that vampire squid, which live in the deep depths of the ocean, boast a unique reproductive strategy that differs from all other living coleoid cephalopods, according to a new study.
Exposure to bisphenol A (BPA), a chemical used in various plastic consumer products, is disrupting turtle reproduction in terms of their sexual differentiation, according to a new study.
It's difficult enough to make friends after moving to a new neighborhood but finding love is a whole other can of worms. And when you're not exactly welcome there, the task could seem nigh-impossible. Such is the case for many invasive species, but researchers are finding that these nuisances are meeting at recognizable landmarks to hook up.
If Barry White were a horse, he'd be the stallion with ALL the mares he could handle. New research has revealed that while mares want their stallion strong, they likewise value a deep-throated whinny, and scientists think they know why.
It is well known that women after a certain age undergo menopause, a trait that is rare in the animal kingdom. However, outside of the human species, killer whales also experience menopause, and these older females apparently make good leaders, a new study says.
It's not every day that you get to call something a "Sparklemuffin" without sounding like a little girl fresh out of kindergarten, but if you ever lay eyes on the stunning Maratus jactatus spider, that's exactly what you can do. You may even get to see a "Skeletorous" while you're at it.
