Would it surprise you to learn that the top movie at the North American box office, a computer-animated family film made for children, is a nakedly racist allegory, a celebration of the urban police state, and an insult to the entire animal kingdom and the natural world at large? The premise of Zootopia is simple: a country bunny named Judy (yes, she's a rabbit) leaves her parents and her hundreds of siblings behind for a life in the big city. The difference between rural and urban living is the first ugly dichotomy the film establishes: farming carrots with your family is framed as a dead-…
You can almost hear the sound of PZ Myers' palm hitting his face as "a couple of vegetarian philosophers with no knowledge of biology" urge humanity to end predation worldwide—so that no more zebras have to suffer at the fangs of a lion, and no more mice at the talons of an owl. Their plea on behalf of prey species, inspired by the model culling of Cecil the lion, calls carnivory simply 'unnecessary;' PZ writes, "it’s as if they are completely unaware of the fact that predation maintains and increases biodiversity, or that there’s more to wildlife than mammals and birds, or that life is a…
An river otter was captured on camera taking on an juvenile alligator...and winning. The battle took place at the Lake Woodruff National Wildlife Refuge in Florida in 2011. More images can be seen on their Facebook page where the images were recently posted, impressive! According to National Geographic, the normal diet of a river otter consists of birds, small rodents, frogs, turtles, crabs, and fish. Let's just add juvenile alligators to the list now. Photo from U.S. FISH AND WILDLIFE SERVICE/FACEBOOK   Perhaps equally impressive is this olive python that was seen strangling then…
I came across this interesting video today from Animal Wire that shows a population of catfish caught hunting pigeons on land: Who knew that catfish had more in common with cats than just their whiskers.
Check out this video of an archer fish (Toxotes jaculatrix) shooting down prey by creating a water jet: Here it is again in slow motion: Until now, the mechanism by which the archer fish produces such a powerful jet of water was a mystery. Contrary to prior hypotheses, the fish do not have specialized internal structures. Dr. Alberto Vailati and colleagues at the University of Milan filmed the fish and found that the initial jet of water travels at an impressive 2 meters per second and the lagging end of the water jet is actually faster. The end result: the head of the water jet is held…
A leopard (Panthera pardus). Image from Wikipedia. SK-54 is a curious fossil. The 1.5 million year old skullcap represents a juvenile Paranthropus robustus, one of the heavy-jawed hominins which lived in prehistoric South Africa, but there is something that makes this skull fragment particularly special. Near one of the sutures along the back of the skull are two neat puncture marks, the hallmark of a leopard. Even though it was initially proposed that SK-54 had been murdered by another australopithecine wielding a weapon of bone or horn, in the late 1960's the paleontologist C.K. Brain was…
Helping out a threatened predator by culling their prey seems like a really stupid idea. But Scandinavian scientists have found that it might be the best strategy for helping some of our ailing fish stocks. Lennart Persson and colleagues from UmeÃ¥ University came up with this counterintuitive concept by running a 26-year natural experiment with the fish of Lake Takvatn, Norway. At the turn of the 20th century, the top predator in Lake Takvatn was the brown trout. Over-fishing sent its numbers crashing, and it was virtually gone by 1980. In its place, a smaller fish - the Arctic char Â-…
