"Jaguars are already one of the world’s most endangered species, but one of the two cubs on display at Zacango Zoo in Mexico is even more rare because it is melanistic. That means the animal appears completely black, although you can actually see spots if you look carefully. The two cubs were bred from different mothers and they’re the first of their kind to be born at the zoo for a decade."

Well-preserved, thanks to just the right combination of conditions over 72 million years, a 16 foot (5 meter) long dinosaur tail has been unearthed by paleontologists in Coahuila, Mexico. Based on evidence, the excavation team believes that the tail could have been from a duck-billed hadrosaur, and they hope to locate more of the dinosaur’s body deeper underground. From Yahoo:
A group of locals discovered the fossil in June 2012. Paleontologists with INAH and the National Autonomous University of Mexico spent about a year surveying the area, and began their excavation on July 2…
Aside from providing a valuable addition to the world’s limited collection of intact dinosaur fossils, the team hopes their findings will help explain the mechanics of how hadrosaur tails moved…
Finding the remains of this web-footed herbivore in such good condition is rare, and will add to the information gathered from previous discoveries. Related hadrosaur reading should include Dakota, the 67 million year old "mummified" hadrosaur that was excavated in North Dakota in 2006.

Professor Brian Cox explains how Monarch Butterflies navigate by “monitoring the position of the sun, and compensating for its location in the sky using their internal timekeeping mechanism… even when it’s cloudy.” This is an episode 5 preview of the BBC’s Wonders of Life. Full screen this.
This short, silent video shares a few behind-the-scenes moments from the ”fish tornado” photograph, titled David and Goliath, taken in Cabo Pulmo, Baja California Sur, Mexico by photographer Octavio Aburto.
"As people have seen this image, I have been getting a lot of messages in my inbox and phone calls asking me “is this photo real?” And “how did you congregate all these fish in one place to take the photo?”
"My response to these questions has been this — of course it is real. Fish, as is the case with many other animals, have certain behaviors that they perform when they reproduce. For example, when monarch butterflies mate they travel hundreds of thousands of kilometers, crossing from Canada down through Mexico to form unbelievable congregations. Sea turtles also have unique reproduction behavior —some travel the entire Pacific just to return to the beaches where they originally hatched. Birds fly hundreds of kilometers to certain areas to nest as well. These behaviors are well known within terrestrial animals and within the scientific community we have also known of these behaviors with fish and other marine creatures for many years. In Cabo Pulmo for example, blacktip reef sharks and mobula rays also congregate in large numbers to mate during the winter season.
"Even after I explain this unique behavior and the spectacular spawning aggregations of fish that occur naturally, some people don’t believe this image is real.
"In some ways I think this photo, and others like it, force people to think about the environment and more specifically in this case the ocean, dwindling fish populations the health of marine ecosystems worldwide and our role in it all."
