Tiktaalik was created in 2006.
It depends on your definition of what it means to "walk". From fossil evidence we know that Tiktaalik favored shallow habitats close to land and that it could very easily support itself against the force of gravity. So it is at least conceivable that Tiktaalik was capable of pulling itself up and out of the water when it needed to. But whether you would call this "walking" is a matter of definition.With this provision in mind... Was Tiktaalik one of the first fish to amble in some manner on land? Quite possibly, yes.
Tiktaalik roseae was created in 2006.
Tiktaalik fossils were found in the Arctic because the region was warm and had a more temperate climate during the time when the fish lived. The movement of tectonic plates over millions of years shifted the location of the Arctic from a tropical area to a colder climate. This is why fossils of Tiktaalik, which originated in a warm marine environment, are now discovered in the Arctic region.
The first to predict the existence of an animal like Tiktaalik was paleontologist Neil Shubin, along with his colleagues. They proposed that transitional fossils between fish and tetrapods would be found in the fossil record, based on evolutionary theory and the anatomical similarities between fish and early land-dwelling vertebrates. Their predictions were confirmed when Tiktaalik, a key fossil representing this transition, was discovered in 2004 in the Canadian Arctic.
a vertebrate
Regardless of the presumed relationship to tiktaalik, you will find gill slits to be present in all vertebrates. In reptiles, the slits would not persist past the embryonic stage but, the crocodiles' jaws were derived from the gill arches. Look up "Ontogeny recapitulates phylogeny."
Well, the Devonian time period was the period of fish, some of the fish are Armed Placoderms (Dunkleosteous), that can grow up to 33 ft., Cartilaginous fish, that are now known as sharks and rays, Tiktaalik fish, that are similar to crocodiles, and Lungfish, that are the only fish to be able to breathe air.
Tiktaalik is significant because it represents a crucial transitional fossil that provides insight into the evolutionary shift from fish to tetrapods (four-limbed vertebrates). Discovered in 2004, its features, such as a neck and robust limb-like fins, illustrate adaptations for movement in shallow water and onto land. This makes Tiktaalik a key example in understanding the evolutionary process and the development of limbs and terrestrial life. Its discovery has enriched our comprehension of vertebrate evolution and the environmental pressures that drove these changes.
Whales eat krill and other fish. Fish eat other fish, depending on what type of fish it is.
yes tiktallik is a vetebrate
There are fish that do eat them, but not ALL fish eat them.
