Vertebrates
Vertebrates comprise all species of animals within the subphylum Vertebrata.
Endotherms
an animal that is dependent on or capable of the internal generation of heat; a warm-blooded animal.
Ectotherms
an animal that is dependent on external sources of body heat.
Lateral line
a visible line along the side of a fish consisting of a series of sense organs that detect pressure and vibration.
Gills
the paired respiratory organ of fishes and some amphibians, by which oxygen is extracted from water flowing over surfaces within or attached to the walls of the pharynx.
Jawless fish
Shark and catfish.
Cartilaginous Fishes
Sturgon, dogfish and smooth hound.
Bony Fishes
Cod, Whiting and pollock.
Swim bladder
he swim bladder, gas bladder, fish maw or air bladder is an internal gas-filled organ that contributes to the ability of many bony fish
Amphibians
Amphibians are ectothermic, tetrapod vertebrates of the class Amphibia. Modern amphibians are all Lissamphibia.
Lungs
each of the pair of organs situated within the rib cage, consisting of elastic sacs with branching passages into which air is drawn, so that oxygen can pass into the blood and carbon dioxide be removed.
Tadpole
the larval stage in the life cycle of an amphibian, particularly that of a frog or toad.
Metamorphosis
Also called transformation. A change in the form and often habits of an animal during normal development after the embryonic stage.
Caecilians
Caecilians are a group of limbless, serpentine amphibians.
Salamanders
Salamanders are a group of amphibians typically characterized by a lizard-like appearance, with slender bodies, blunt snouts, short limbs projecting at right angles to the body, and the presence of a tail in both larvae and adults.
Frogs
A frog is any member of a diverse and largely carnivorous group of short-bodied, tailless amphibians composing the order Anura.
Toads
Toad is a common name applied to certain frogs, especially of the family Bufonidae, that are characterized by dry, leathery skin, short legs, and parotoid glands.
Reptiles
Reptiles are tetrapod animals in the class Reptilia, comprising today’s turtles, crocodilians, snakes, amphisbaenians, lizards, tuatara, and their extinct relatives.
Amniotic Eggs
The structure of the amniote egg. Inside the egg are a series of fluid-filled membranes which permit the embryo to survive: the amnion, allantois, yolk sac, and chorion.
Turtles
Turtles are reptiles of the order Testudines characterised by a special bony or cartilaginous shell developed from their ribs and acting as a shield.
Tortioses
Tortoises are a family, Testudinidae, of land-dwelling reptiles in the order Testudines. Tortoises are shielded from predators by a shell.
Crocodiles
Crocodiles or true crocodiles are large aquatic reptiles that live throughout the tropics in Africa, Asia, the Americas and Australia.
Alligators
An alligator is a crocodilian in the genus Alligator of the family Alligatoridae. The two living species are the American alligator and the Chinese alligator.
Snakes
nakes are elongated, legless, carnivorous reptiles of the suborder Serpentes that can be distinguished from legless lizards by their lack of eyelids and external ears.
