Polypterus senegalus

Cynthia Lee, McGill University About 400 million years ago a group of fish began exploring land and evolved into tetrapods – today's amphibians, reptiles, birds, and mammals. But just how these ancient fish used their fishy bodies and fins in a terrestrial environment and what evolutionary processes were at play remain scientific mysteries. Researchers at McGill University published in the journal Nature, turned to a living fish, called Polypterus, to help show what might have...

Evolution Of Hips Simpler Than Suspected
2013-05-15 12:04:37

April Flowers for redOrbit.com - Your Universe Online The evolutionary path from the bone structure of the fish to the complex, weight-bearing hips of walking animals was a much simpler process than previously thought, according to a new study. About 395 million years ago, the first tetrapods, or four-legged animals, stepped onto land. This transition was accomplished using strong, weight-bearing hipbones and a connection through the spine via the ilium. These features were not present...

Beneath the gondolas in the remains of a great Aztec lake lives a monster-like creature called the axolotl, which looks something like a Muppet with a slimy tail, feather-like gills and mouth that curls into an strange smile.Also known as the "water monster" and the "Mexican walking fish," the axolotl (pronounced ACK-suh-LAH-tuhl) was a crucial part of Aztec legend and diet.  Despite Mexico City's sprawling development, the foot-long salamander survived until now in the polluted canals...

Some 375 million years ago, a unique fish existed with features in its head that helped pave the way for vertebrate animals to live on land, scientists said on Wednesday. Now, new research is providing the first glimpse at the internal head skeleton of Tiktaalik roseae. The transition from aquatic to terrestrial lifestyle involved complex changes not only to appendages (fins to limbs) but also to the internal head skeleton, researchers report in the recent issue of the journal Nature....

The Axolotl, Ambystoma mexicanum
2014-02-03 08:59:54

Axolotl (Ambystoma mexicanum) may also be referred to as the Mexican salamander or the Mexican walking fish. The Axolotl is a member of the Ambystomatidae family and although its common name may suggest it is a fish, it is an amphibian. Axolotl are found exclusively in Mexico. The species situates, near Mexico City, on the bottom of Xochimilco’s lakes. Unlike most salamanders, Axolotl keep its larval features throughout its entire life and very rarely ever emerge from water. A condition...
