The evolution of hind legs actually began as enhanced hind fins, according to the newly discovered, well-preserved pelvis and a partial pelvic fin from Tiktaalik roseae—a 375 million-year old transitional species between fish and the first legged animals.
The genome of the coelacanth, a creature with an evolutionary history that is both enigmatic and illuminating, has been decoded by the Genome Center of the Broad Institute of MIT and Harvard, and analyzed by an international team of researchers.
The famous fossil fish species Tiktaalik roseae lived in the brutal Devonian environment 375 million years ago and is receiving scientific acclaim for providing some of the best evidence to date of the evolutionary change from lobe-finned fish to four-limbed animals.
Researchers have revealed that the African lungfish can use its thin pelvic limbs to propel itself forward.
A new study finds that sharks, paddlefishes and certain other aquatic vertebrates have a sixth sense: the ability to detect weak electrical fields in the water, and to use this information to detect prey, communicate and orient themselves.
A study into the muscle development of several different fish has given insights into the genetic leap that set the scene for the evolution of hind legs in terrestrial animals.
The Academy of Natural Sciences today announced the discovery of a new species of large predatory fish that prowled ancient North American waterways during the Devonian Period, before backboned animals existed on land.
A mass extinction of fish 360 million years ago hit the reset button on Earth's life, setting the stage for modern vertebrate biodiversity.
Fossilized footprints of a mysterious, long-extinct creature in a Polish quarry have caused paleontologists to reconsider traditional thinking of how sea-based vertebrates moved to land.
By Friedman, Matt; Blom, Henning ABSTRACT- A new actinopterygian, Cuneognathus gardineri new genus and species, is described from the Devonian (Famennian) Obrutschew Bjerg Formation of East Greenland on the basis of multiple incomplete specimens.
West African Lungfish thrive in fresh water in the West African countries of Senegal, Niger, Gambia, Volta and Chad basins, where the water temp ranges from 77 to 86 degrees. They also can be found in tributaries of the Chari River in Western Sudan. It is eel-like in looks with a long slender body containing 34 - 37 pairs of ribs. The body can be 9 - 15 times the length of its head with small eyes and a prominent snout. The pectoral fins (fins on each side closest to the head) are fringed...
The marbled lungfish is found mainly in the Nile river, in the northeastern continent of Africa. It also is found in such lakes as the Albert, Edward, Tanganyika, Victoria, Nabugabo, No and Kyoga, all centrally located in Africa at the southern end of the Nile. They live in the shallow areas of these lakes, streams, rivers, and swamps. During the dry season, many of the areas will dry up and when this occurs the marbled lungfish will bury themselves in the mud leaving just a small opening...
The Queensland lungfish, Neoceratodus forsteri, also known as Burnett salmon and Barramunda, is the sole member of the family Ceratodontidae, and one of the only six lungfish species that remain. Olive or dull brown in color, it grows to about 59.06 in (150 cm) in length, more commonly 39.37 (100 cm). It is native to the Burnett and Mary River systems of south-east Queensland, but has been introduced into other nearby rivers, including the Brisbane River. It prefers still or slow-flowing...
