cold blooded Flashcards
vertebrates
Animals with a backbone
endotherms
able to maintain a constant body temperature by internal means; warm- blooded
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.
ectotherms
an animal that is dependent on external sources of body heat.
jawless fishes example(2)
heterostraci,arandaspididae,haikouichthys
cartilaginous fishes 3 examples
shark,batoids,chimaera
bony fishes 3 examples
sunfish,walleye,and goldfish
swim bladder
The swim bladder, gas bladder, fish maw or air bladder is an internal gas-filled organ that contributes to the ability of many bony fish (but not cartilaginous fish) to control their buoyancy, and thus to stay at their current water depth without having to waste energy in swimming.
amphibians
cold blooded vertebrate; double life means it lives on land & water; has gills and lungs, lays eggs in water, smooth skin, external fertilization. For example: Frogs, Newts Salamanders
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. Lungs are characteristic of vertebrates other than fish, though similar structures are present in some other animal groups.
tadpole
A tadpole (also called a pollywog) is the larval stage in the life cycle of an amphibian, particularly that of a frog or toad. They are usually wholly aquatic, though some species have tadpoles that are terrestrial.
metamorphosis
The organism looses its gills. the organism loses its tails. It grows legs. The leg becomes longer. It develops lungs (frog)
caecilians description
looks like a snake
salamanders description
slender body, long tail, short legs
frogs description
jump,slimy, and i hate them
toads
A frog is any member of a diverse and largely carnivorous group of short-bodied, tailless amphibians composing the order Anura.
reptiles
Cold-blooded,dry scaly skin, lay eggs on the land with leathery shells, lungs, internal fertilization. For example: lizards, snakes, turtles, alligators
amniotic eggs
Amniotes are a clade of tetrapod vertebrates comprising the reptiles, birds, and mammals. Amniotes lay their eggs on land or retain the fertilized egg within the mother
turtles
Turtles are reptiles of the order Testudines characterized by a special bony or cartilaginous shell developed from their ribs and acting as a shield. “Turtle” may refer to the order as a whole or to fresh-water and sea-dwelling testudines.
tortosies
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. Crocodylinae, all of whose members are considered true crocodiles, is classified as a biological subfamily.
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. In addition, several extinct species of alligator are known from fossil remains.
snakes
Snakes are elongated, legless, carnivorous reptiles of the suborder Serpentes. Like all squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales.
