I can remember the first time I saw one, at the St. Louis Zoo, and the feeling that certain death was just on the other side of the glass. I could not get over the snake’s size — this one was about 12 feet long. I was used to looking at giant snakes in zoos (I always made a beeline for the reptile house), but pythons did not seem so scary to me because they rarely moved. This sleek, agile and very alert snake was a king cobra, the largest venomous snake in the world and an icon to all snake enthusiasts, including this writer. |  |

 | El cambio climático podría estar acelerando el proceso de desaparición del coquí, una diminuta rana autóctona de Puerto Rico que es símbolo de la isla y se caracteriza por un particular sonido, según un estudio de la Universidad de Cornell. «En Puerto Rico ya hemos perdido tres de las diecisiete especies de ranas únicas de la isla de desarrollo directo (que no pasan por la fase de renacuajo) desde los años setenta», explicó a Efe la investigadora puertorriqueña Ana Longo, que integra el equipo multidisciplinar responsable de este estudio. |
One hundred million years ago in what is now Myanmar, a lizard snapped off a dragonfly’s head and tried to dash away. Unfortunately, the reptile didn’t escape with its snack: Both creatures were trapped in sticky tree resin, leaving behind a grisly fossilized scene. The find, reported in the 2010 issue of the journal Palaeodiversity, is the oldest example of a dragonfly preserved in amber, or fossilized tree resin. But what makes the find really interesting is the snapshot of ancient life that looks familiar today, said George Poinar, an entomologist and emeritus professor at Oregon State University. |  |
