Wild dogs know use democracy to make decisions:

Scientists studying African wild dogs in Botswana have found members of this endangered species use sneezes to vote on when the pack will move off and start hunting.

Sheep can recognize human faces on pictures. I wonder if they're better than people at recognizing sheep faces on pictures?

Quote:
Sheep can be trained to recognise human faces from photographic portraits -- and can even identify the picture of their handler without prior training -- according to new research.

So, seals that can't get laid, rape and even kill penguins to satisfy their urges...

Quote:
It turns out that, when seals aren't getting any, they turn violent, coercing penguins to have sex with them. If the seals don't get what they want, they may rape the penguins several times and may even eat the helpless birds when they're done.

Female hyenas have a fully erect clitoris that resembles male genitalia. They even go as ar as having a tuft of fur that resembles a scrotum. Worse even so, they have to give birth, and roughly 10% die in their first pregnancy.

Giraffes don't have mating seasons but rather cycles like humans. Males know a females time by hitting her repeatedly in the bladder until she pees in his mouth. The male is able to take the hormones.

Also, blue whales are the biggest creature to EVER live on the planet.

The world's most successful predator on land, in terms of the percentage of hunts that are successful, is the African wild dog. Around 85% of their hunts end in a kill.

For comparison around 30% of lion hunts are successful and 33% for the hyena.

Dogs are smarter than cats:

Quote:
PHOENIX — Dog people have long known that canines are smarter than felines. The fact that there are no service cats or drug-sniffing cats making that abundantly clear.

A new study proves it beyond a biological doubt, giving dog owners the neuroscientific evidence they need to end the argument.

Researchers at Vanderbilt University found that a dog’s cerebral cortex contains more than twice the neurons of a cat’s brain.

Neurons are cells associated with thinking, planning and complex behaviors, thus strongly related to intelligence.

And dogs have it way over cats in the neuron department.\

Vanderbilt neuroscientist Suzana Herculano-Houzel (full disclosure: an avowed dog person) said canines have roughly 530 million cortical neurons, while felines have about 250 million.
Are dogs smarter than cats? Yes, and science proves it

And a further interesting fact on the number of neurons in a canines brain. At 530 million it is exactly the same number as that of the Eurasian Jay. Brain mass of the Grey Wolf is 119.5g, brain mass of the Jay is 4.59g, or 26 times smaller, and with the neurons being more tightly packed lets information travel around the corvid brain far quicker than that of the wolf. And for completeness on a wolf-corvid theme, the raven has slightly more than twice as many pallium neurons as a wolf at 1.2 billion in a brain 8.5 times smaller in mass than a wolf.

Bonobos prefer bullies:

Never trust anyone who is rude to a waiter, advice columnists say. But while humans generally prefer individuals who are nice to others, a Duke University study finds bonobos are more attracted to jerks. The fact that our closest primate relatives prefer bullies suggests that an aversion to creeps is one of the things that makes humans different from other species, and may underlie our unusually cooperative nature.
