Draw a cladogram (below, or on reverse of page) indicating the hypothesis of relationships for the following Craniate taxa: Myxiniformes (hagfish) Petromyzontiformes (Lamprey) Chondrichthyes Actinopterygii Actinistia (coelacanths) Dipnoi (lungfishes) Lissamphibia Testudines (Turtles) Lepidosauria . The structure of the gills is similar to that of Rohu. Vertibrate Gonads. They do not have any scales in the head region while their body is covered with cycloid/ ganoid/ ctenoid scales. Systematic Position of Rohu 2. Since finding mates can be hard in the deep sea, females release pheromones, which attract males. Introduction to Fishes "Fish": poikilothermic, aquatic chordate with appendages developed as fins (when present), whose chief respiratory organ are gills and whose body is usually covered in scales Paraphyletic group because of tetrapods All fishes… have distinct head region (eyes, mouth, etc.) primary functions of respiratory system. General Description Characteristics Classification 4. Olfactores is a clade within the Chordata that comprises the Tunicata (Urochordata) and the Vertebrata (sometimes referred to as Craniata).Olfactores represent the overwhelming majority of the phylum Chordata, as the Cephalochordata are the only chordates not included in the clade.This clade is defined by a more advanced olfactory system which, in the immediate vertebrate generation, caused .

Chondrichthyes (/ k ɒ n ˈ d r ɪ k θ i. iː z /; from Ancient Greek χόνδρος (khóndros) 'cartilage', and ἰχθύς (ikhthús) 'fish') is a class that contains the cartilaginous fishes that have skeletons primarily composed of cartilage.They can be contrasted with the Osteichthyes or bony fishes, which have skeletons primarily composed of bone tissue. ADVERTISEMENTS: 3. Latex injection (blue) of the pulmonary system in a duck. ADVERTISEMENTS: In this article we will discuss about Rohu:- 1. General Characters of Actinopterygii: 1. Osteichthyes includes the largest number of living species of all scientific classes of vertebrates, more than 28,000 species. Habit and Habitat of Rohu 3. The lata fish is capable of living in absence of water for a considerable period of time. al. . 12. They are found in fresh, marine, and brackish water. An example of an Actinopterygii is the ocean sunfish, which is the most massive bony fish in the world. -primary transport system-carries O2 and nutrients from respiratory and digestive organs to all tissues and cells of body-removes CO2 and excretory products from tissues to sites of removal (lungs, kidneys) -distributes heat throughout body -combats disease carrying leukocytes, immunoglobulins, and other immune cells -repairs tissues In 1938, a South African fisherman pulled a strange catch from the waters of the Indian Ocean. The blood of fishes is similar to that of any other vertebrate. 6. They reproduce by spawning. Long dorsal fin base with about 48 dorsal rays. Pulmonary vs systemic circuits. The rest of the actinopterygians, which includes the vast majority of species, are in the subclass Neopterygii: "In their great numbers and degree of anatomical diversity, the modern ray-finned fishes may be considered the most successful of all vertebrates" (Caroll, 1986:136 in Helfman et. Skeletal System - Vertebral Column. The nostrils help in aerial respiration. The second conjecture is the inter-tidal hypothesis presented in 2010 by a team of paleontologists who argued that The Sarcopterygii, or lobe-finned fishes, may have first emerged from the earth's intertidal zone and not from internal bodies of water. Skeletal System - Visceral Arches. Goldfish get their oxygen from water. Circulatory characteristics of fish, amphibians, reptiles, birds, and mammals . Both of these fish are capable of breathing air using a buccal force pump, and both of these fish also have gills. Genital and excretory systems closely related, utilizing common ducts and pathways. Respiratory system. Water as a respiratory medium, relative to air; Low in O 2 (typically about 1/30th) Viscous (50x), therefore difficult to move; Dense (800x), therefore difficult to move Class Actinopterygii and Class Sarcopterygii 1. Respiratory System of Lata Fish: The primary respiratory organs are four pairs of gills, two pairs on either side. The Actinopterygii are divided into two classes: Cladistia (bichirs), represented by a single modern order (Polypteriformes) restricted to Africa, and Actinopteri, with the subclasses Chondrostei and Neopterygii. The primary bronchi after entering the lung into secondary bronchi which divide into smaller and smaller bronchioles, finally terminating in tiny alveoli or blind pockets in which there is an exchange of gases. The overwhelming majority of all fish species, over 95%, are found in the class Osteichthyes. Before mating, the male picks out a mate and then chases after her. The arapaima is the largest of the extant air-breathing freshwater fishes. Oxygen moves from the water to the blood as the water flows over the gills. Therefore, the presence of air-filled bladders or lungs in different groups of fishes is an example of convergent evolution. Osctracoderms. Class Actinopterygii and Class Sarcopterygii 1. Despite the fact that air contains 40 times the oxygen in water, sufficient oxygen doesn't make it into the blood. Bony fishes share several distinguishing features: a skeleton of bone, scales, paired fins, one pair of gill openings, jaws, and paired nostrils. The water which has oxygen goes through an opening in the fish's throat that leads to the gills. It takes two months for the eggs to hatch. 9. 10. For some time, it has been known then, that a SVS is restricted to the Actinopterygii in which it evolved to accommodate some feature of their that the elasmobranch species have a branchial non- respiratory vascular system in the form of a central physiology as they began to diverge from the Acanthodii venous sinus supplied through . 1997:162). From water to land. Respiration involves the exchange of two gases, oxygen (O 2) and carbon dioxide (CO 2).The respiratory system is made up of all the organs that are involved in the function. • Bony fish have an operculum, which is a protective bony plate covering their vulnerable gills. The respiratory system of the mammal is much less complicated than that of the bird. Carl Gans, Christopher J. Some have a spindle-shaped or elongated body as well. As a fish swims, it gulps up water. The lata fish is capable of living in absence of water for a considerable period of time. These respiratory systems have been forced to continually develop new designs depending on new evolutionary pressures from changing environments. and brain protected by braincase Most fishes… Males are ~40x smaller. Respiratory system, including either gills or lungs, located closely to the pharynx or throat. They swim with the help of their tail.
