ABSTRACT: This research paper is mainly addressing the morphological, physiological, genetically and her own ecological behavior and also biological geography of ancient jawless Fish. Actually ancient jawless fish are living fossils, Proper examples of vertebrate species. The bodies of this fish are covering with skin or covered with in some extinct cases that means in some extinct bony plate. Ancient Jawless fish are exothermic as well as all fish. They keep their body temperature from the surrounding water of their body. The metabolism of these types of fish is slow in cold water. They are able to produce number of egg only once, cause after doing so their cloaca remains open for allowing a fungal infestation to kill them. The jawless fish are represents two groups for living one of them are hagfish and the other is lampreys. These types of fish are the only one living representatives of the creatures of ancient that also gave rise to the fish and finally humans. However there are some differences between hagfish and lampreys one of them lampreys are generally vertebrates. On the other hand hagfish are not considered as vertebrates at all.
