Whois & Analysis for dearava.com

A fish is any member of a group of animals that consist of all gill-bearing aquatic craniate animals that lack limbs with digits.

They form a sister group to the tunicates, together forming the olfactores.

Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups.

Tetrapods emerged within lobe-finned fishes, so cladistically they are fish as well.

However, traditionally fish are rendered obsolete or paraphyletic by excluding the tetrapods (i.e., the amphibians, reptiles, birds and mammals which all descended from within the same ancestry).

Because in this manner the term "fish" is defined negatively as a paraphyletic group, it is not considered a formal taxonomic grouping in systematic biology.

The traditional term pisces (also ichthyes) is considered a , but not a phylogenetic classification.

The Pannonian Avars also known as the Obri (in Ruthenian chronicles), the Abaroi and Varchonitai (Warhonits) (in Byzantine sources), and the "Pseudo-Avars" and Varchonites (by the Göktürks), were a group of Eurasian nomads of unknown origin during the early Middle Ages.

The name Pannonian Avars (after the area in which they eventually settled), is used to distinguish them from the Avars of the Caucasus – who may or may not have been an unrelated people.
