- The Sarcopterygii, or lobe-finned fishes, is a clade containing the coelacanths, lungfishes, tetrapods, and their fossil relatives, including the osteolepiformes and panderichthyids. They are the sister group to the ray-finned fishes (Actinopterygii), together forming the bony fishes (Osteichthyes).hese lobe-fins gave rise to the paired limbs of tetrapods, with the single bones representing the humerus (forelimb) and femur (hindlimb). The once-diverse coelacanths (Actinistia) are now represented by just two species in a single genus-Latimeria chalumnae and L. menadoensis.

- Osteichthyes are a very diverse group of bony fish. They are Ectothermic, which means they depend on the surrounding environment for their body temperatures. Osteichthyes live in all types of fresh and salt waters.steichthyes (Bony Fish) are the most species-rich and morphologically diverse lineage of all vertebrates. 1  brain. 2  spinal cord. 3  cranial nerves. 4  spinal nerves. 5  sensory organs 6  -. eyes-good eyesight. 7  no eyelids, thus permitting a maximum amount of. 8  light. 9  ears-no external opening.

Bowfin (Dogfish) Bowfin (Dogfish). A medium-sized, greenish fish, the bowfin can be found in clear lakes and slow streams through much of Minnesota. Bowfin survive in murky, oxygen-depleted water by rising to the surface and gulping air into their air bladders.his primitive fish was around when dinosaurs roamed the earth. It is also known as a dogfish. The bowfin is a tubular, olive-green fish with a scaleless head and two barbels on its face. Its dorsal fin stretches most of the length of its back.

Introduction to the Sarcopterygii The most important features of lobe-finned fish is the lobe in their fins. Unlike other fish, Lobe-finned fish have a central appendage in their fins containing many bones and muscles. The fins are very flexible and potentially useful for supporting the body on land, as in lungfish and tetrapods (vertebrates with four limbs). Tetrapods are thoughto to have evolved from primitive lobe-finned fish.

Introduction to the Sarcopterygii from fins to legs. The Sarcopterygii are the lobe-finned fish and the tetrapods. The name Sarcopterygii (or sometimes Crossopterygii) used to refer only to the fish members of the group, but since it has become clear that the Tetrapoda evolved from sarcopterygian fish, the definition of the group has been expanded.he Sarcopterygii are the lobe-finned fish and the tetrapods.

Blue Moorii Cichlid They are pretty difficult to breed in captivity, so most of these fish are wild caught. Other common names it is known by include Blue Dolphin Cichlid, Malawi Blue Dolphin, Hump-head, Blue Lumphead, Hap moorii, and Humphead Mouthbrooder. They inhabit sandy coastal areas at depths between 10 - 49 feet (3 - 15 m).

- The Chondrichthyes are the cartilaginous fishes including the sharks, rays, skates and chimaeras. The Osteichthyes are the bony fish. Both of these groups became established d … uring the Devonian Period about 400 million years ago.The Chondrichthyes differ from the Osteichthyes in many respects, including their skeletons, scales, teeth, buoyancy, swimming, gills and reproduction. Scales:   Cartilaginous fish have large scales called placoid scales. These have a bone like base embedded in the skin and a backward projecting enamel covered dentine spine. The whole thing has a central pulp cavity (rather like the structure of teeth). The epidermis and dermis form placoid scales.

- Because the term fish is defined negatively, and excludes the tetrapods (i.e., the amphibians, reptiles, birds and mammals) which descend from within the same ancestry, it is paraphyletic, and is not considered a proper grouping in systematic biology.ish do not represent a monophyletic group, and therefore the evolution of fish is not studied as a single event. Early fish from the fossil record are represented by a group of small, jawless, armored fish known as Ostracoderms. Jawless fish lineages are mostly extinct.

Pleuronectidae Righteye flounders are a family, Pleuronectidae, of flounders. They are called righteye flounders because most species lie on the sea bottom on their left sides, with both eyes on their right sides. The Paralichthyidae are the opposite, with their eyes on the left side.

- Latimeria chalumnae and L. menadoensis are the only two known living coelacanth species. The word coelacanth is derived from the Greek for “hollow spine”, because of the fish's unique hollow spine fins. Coelacanths are large, plump, lobe-finned fish that grow up to 1.8 meters.They are nocturnal piscivorous drift-hunters. The body is covered in cosmoid scales that act as armor.he word coelacanth is derived from the Greek for “hollow spine”, because of the fish's unique hollow spine fins.

Yellow Perch, Perca flavescens The Yellow Perch are members of the Percidae or perch family, are characterized by a dorsal fin, which is completely divided into a spiny and a separate soft-rayed portion. Both are important game fish in the Great Lakes area. Yellow Perch have the distinction of being the most frequently caught game fish in Michigan.

Bony Fishes Class - Osteichthyes. Class Osteichthyes includes all bony fishes. Like all fishes, Osteichthyes are cold-blooded vertebrates that breathe through gills and use fins for swimming. Bony fishes share several distinguishing features: a skeleton of bone, scales, paired fins, one pair of gill openings, jaws, and paired nostrils. Osteichthyes includes the largest number of living species of all scientific classes of vertebrates, more than 28,000 species.

- Vertebrates include the jawless fish and the jawed vertebrates, which includes the cartilaginous fish (sharks and rays) and the bony fish.A bony fish clade known as the lobe-finned fishes is included with tetrapods, which are further divided into amphibians, reptiles, mammals, and birds.agfish do, however, possess a cranium. For this reason, the vertebrate subphylum is sometimes referred to as  Craniata  when discussing morphology. Molecular analysis since 1992 has suggested that the hagfish are most closely related to lampreys, and so also are vertebrates in a monophyletic sense.

Burbot The burbot is the only gadiform freshwater fish. It is also known as bubbot, mariah, freshwater ling, the lawyer, coney-fish, lingcod, freshwater cusk, and eelpout. The species is closely related to the marine common ling and the cusk. It is the only member of the genus Lota. For some time of the year, the burbot lives under ice, and they require frigid temperatures to breed.

Fish Anatomy The caudal (tail) fin is used for propulsion. The types of caudal fins are: 1  Heterocercal: the vertebrae extend into a larger lobe of the tail. 2  Epicercal: the upper lobe is larger, as in sturgeons and many sharks. 3  Hypocercal: the lower lobe is larger, as in flying fish.
