Scientists often need to figure out ways of understanding processes they can't see. Usually, that results in research much more mundane than that carried out by Dara Orbacha researcher at Dalhousie University in Canada. That's because Orbach is aiming to understand reproduction in animals like dolphins, harbour porpoises and harbour seals.
A: Copulation is the most direct possible interaction between males and females, but we know so little about it largely due to the physical challenges of studying it, especially with underwater creatures. We do this by looking at tissue samples from animals that died of natural causes. We use whole penises and whole vaginas.
Being a scientist can be a strange job. Like on the days when your work involves inserting the artificially inflated penis of a dead dolphin into the recently thawed vagina of another dead dolphin, all inside a CT scanner. For new research presented yesterday April 23 at the annual meeting of the American Association of Anatomists in Chicago, scientists did just that in the pursuit of a better understanding of how male and female anatomy co-evolve.
This was the sight that greeted one shocked family on safari this week, who got an eyeful of the trio going at it in the wilds of the West Midlands. David Attenborough this ain't In a video captured at the scene, parents were forced to cover the eyes of their three kids as the male lions began to mount one another. And, as it turns out, these kings of the jungle are masters of seduction - often sleeping for 20 hours a day, but awakening to mate almost exclusively for the other four.

Dolphin clitorises are incredibly similar to those of humans. In a recent studyscientist Dara Orbach, a research associate at Mount Holyoke College, and Patricia Brennan, an assistant professor of biology completed autopsies on 11 dolphins who had died of natural causes. They dissected their reproductive organs and created 3D tomography CT scans of their vaginas.
Dolphin is a common name of aquatic mammals within the infraorder Cetacea. The term dolphin usually refers to the extant families Delphinidae the oceanic dolphinsPlatanistidae the Indian river dolphinsIniidae the New World river dolphinsand Pontoporiidae the brackish dolphinsand the extinct Lipotidae baiji or Chinese river dolphin. There are 40 extant species named as dolphins.
Animals do some pretty freaky stuff to keep making more of themselves, like tricking their partners into having sex or even killing them and eating them after doing it for an extra boost of baby-making energy. Look at their little faces! How do dolphins have sex, anyway? Magical rainbows beaming back and forth between them?
Procreating is serious business in the animal kingdom, and Mother Nature has gone out of her way to cleverly ensure the survival of her many, many denizens. From sex organs with multiple heads to prodigious shafts exceeding an animal's own body length, here are 12 of the weirdest and often scariest animal penises on the planet:. But what makes this soft-bodied marine mollusk particularly different is its ability to grow a new penis within 24 hours.
