Video: Seals Caught Raping Penguins !

Seal forcefully coerces with penguin
Someone's having a really bad day!
In a study published a few days ago, researchers from the Mammal Research Institute at the University of Pretoria, South Africa reported three incidents of fur seals (Aptenodytes patagonicus) sexually harassing and coercing with king penguins!

The authors even took footage of the large mammals forcefully putting the birds to the ground and attempting to mate with them! The incidents took place at the sub-Antarctic Marion Island, on Goodhope Bay and Funk beach.

These observations are similar to a previously published observation (2006) that occurred in the same island on Trypot beach. All four incidents followed a similar pattern. The male seal first chases, captures and mounts the penguin and then "attempts copulation several times with periods of rest in between".

In three of these incidents the penguins were released relatively unharmed (although one was bleeding from the cloaca due to penetration) but the fourth got really, really unlucky. It was killed and then eaten by the seal. This may have been because unlike the others he was "energetically opposing the seal’s actions".

The incidents lasted anywhere from 10 to a whooping 85 minutes!

"Honestly I did not expect that follow up sightings of a similar nature to that 2006 one would ever be made again, and certainly not on multiple occasions." said Nico de Bruyn, one of the authors, to BBC.

Why fur seals are engaging in these bizarre sexual activities is puzzling. Initially it was hypothesized that "the sexual coercion event [in 2006] was a result of the seal’s predatory behavior towards the penguin being redirected into sexual arousal". But in the 2011 incident, the seal was killed and eaten which makes this hypothesis less plausible.

For now the most prevailing theory is that the whole sex with penguins thing has become a learned behaviour. But how did this behavior originally begin still remains a mystery.

"Determining the drivers of the unusual bebehaviorescribed here is nearly impossible.", an extract from the stydy.

  1. It seems like the more intelligent a mammalian species is - humans and cetaceans being [pretty well tied for first place - the more time and effort they devote to recreational sex and the greater the variety of what we might unkindly term kinks and perversions they come up with. Sadly, the seals' practice of coercive "bestiality" may be taken as evidence of their capacity for creativity.

  2. That's one of the most disturbing things I've witnessed in a long time. You really should change the verbiage from "Seal having sex with a penguin", to "Seal raping a penguin", because the penguins don't seem to be enjoying this at all.
