Chondrichthyes Cartilaginous fishes (chondrichthyes) are an ancient group of animals, having changed little in 100 million years. However ancient does not mean obsolete, but rather that they hit on a very successful body plan early on.
Osteichthyes
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.
Amphibian frogs or salamander
Reptilian spiny creatures like crock idol or sea snake
Aves flying sea birds like seagl or pelegan
Mamal fish such as bass cat crappi and trout

Vertebrata- Vertebrates /ˈvɜrtɨbrəts/ are animals that are members of the subphylum Vertebrata /-ɑː/ http://biodidac.bio.uottawa.ca/thumbnails/filedet.htm?File_name=oste020b&File_type=GIF(chordates with backbones)
Chondricthyes- Chondrichthyes or cartilaginous fishes are jawed fish with paired fins, paired nares, scaleshttp://www.ucmp.berkeley.edu/vertebrates/basalfish/basking.jpg
Osteichthyes- Osteichthyes /ˌɒstiːˈɪkθi.iːz/, also called bony fish, are a taxonomic group of fish that have bone http://bio1151.nicerweb.com/Locked/media/ch34/osteichthyes.html
Amphibia- Amphibians are ectothermic, tetrapod vertebrates of the class Amphibia. They inhabit a wide variety of habitats with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. http://www.ucmp.berkeley.edu/vertebrates/tetrapods/amphibintro.html
Reptilia- Reptiles, the class Reptilia, are an evolutionary grade of animals, comprising today's turtles, http://www.hdwpapers.com/chameleon_reptilia_wallpaper-wallpapers.html
crocodilians- The Crocodilia are an order of large, predatory, semiaquatic reptiles. They appeared 83.5 million years ago in the Late Cretaceous period and are the closest living relatives of birds http://www.reptilegardens.com/reptiles/crocodilians.php
Aves- Birds are feathered, winged, two-legged, warm-blooded, egg-laying vertebrates. Aves ranks as the tetrapod class with the most living species, approximately ten thousand. http://commons.wikimedia.org/wiki/File:Parque_das_aves.jpg
Mammalia- Mammals are a clade of endothermic amniotes distinguished from the reptiles and the birds by the possession of hair, three middle ear bones, mammary glands in females, and a neocortex. http://visual.merriam-webster.com/images/animal-kingdom/ungulate-mammals/examples-ungulate-mammals_6.jpg

Make a chart detailing characteristics and a picture of a marine member for each class of vertebrates we will be covering the rest of the semester:Classes:
Chondricthyesfrom Greek χονδρ- chondr- 'cartilage', ἰχθύς ichthys 'fish') or cartilaginous fishes are jawed fish with paired fins, paired nares, scales, a heart with its chambers in series, and skeletons made of cartilage rather than bone.Osteichthyes also called bony fish, are a taxonomic group of fish that have bone, as opposed to cartilaginous, skeletons.Mammalia are a clade of endothermic amniotes distinguished from the reptiles and the birds by the possession of hair, three middle ear bones, mammary glands in females, and a neocortex (a region of the brain).

Agnatha- has no jaw, has gill slits, have a round sucking mouth, eyes covered by thick skin, lives in colonies, feeds on inner tissue,Chondricthyes- jaws with teeth, paired fins, only small fractions are members of this group, some grow 7 meters across.Osteichthyes- success due to light, hard strong bones support them, have a gas filled swim bladder, and they have great speed.Amphibia-Amphibians have various characteristics that are unique to them including cold bloodedness. They also begin their lives breathing using their gills before developing to use their skins and lungs. Most amphibians are also carnivorous, feeding on fish, small reptiles, crustaceans and other amphibians.Reptilia-Reptilia, presented as a Class in our classification, includes turtles (Testudines), snakes and lizards (Lepidosauria), crocodiles and their relatives (Crocodilia), and birds (Aves), as well as a number of extinct groups.Aves-Birds are vertebrates with feathers, modified for flight and for active metabolism. Birds are a monophyletic lineage, evolved once from a common ancestor, and all birds are related through that common origin.Mammalia-Although mammals share several features in common, Mammalia contains a vast diversity of forms. The smallest mammals are found among the shrews and bats, and can weigh as little as 3 grams.

Classes:
Agnatha - lack jaws; no paired appendages; have gill slits; have openings to slime glands; have round sucking mouths surrounded by organs sensitive to touch; tails are flattened; eye are covered by thick skin
Chondricthyes - skeleton is made of cartilage; have jaws with teeth; have paired fins
Osteichthyes - 27,000+ species of bony fish; success due to light, hard, strong skeleton that supports them; most numbers are successful of all vertebrates; they have a gas filled swim bladder to help maintain neutral buoyancy; have independently movable fins for well controlled swimming; capable of great speed for pursuit or avoidance of predators; have effective camouflage; have social organization; have an orderly pattern of migration; have the ability in defensive school
Amphibia – cold blooded; breathing using their gills before developing to use their skins and lungs; most are carnivorous
Reptilia – are ectothermic; breathe air-using lungs; are covered with scales and impermeable skin; have salt glands that concentrate and excrete salt
Aves – are endotherms – they generate and regulate metabolic heat; have thing hollow bones without fatty insulation; have light weight beak replacing jaws and teeth; chambered heart to circulate blood under high pressure; have a respiratory system that can accept large quantities of oxygen; all birds lay eggs on land
Mammalia - endothermic; breathe air; give birth to living young; young suckle milk produced in mammary glands; have hair at some time during life; streamlined body shape with limbs adapted for swimming; generate internal body heat through high metabolic rate and conserve the heat by layers of insulation; a respiratory system modified to collect and retain large amounts of oxygen; many osmotic adaptations allow marine mammals to do away with the need for fresh water
