cold blooded vertibrates Flashcards

Vertebrates represent the overwhelming majority of the phylum Chordata, with currently about 64,000 species described
vertebrates
is an organism that maintains its body at a metabolically favorable temperature, largely by the use of heat set free by its internal bodily functions instead of relying almost purely on ambient heat
Endotherms
an animal that is dependent on external sources of body heat.
Ectotherms
is a system of sense organs found in aquatic vertebrates used to detect movement and vibration in the surrounding water.
Lateral Line
are tissues which consist of cloth and fabric structures called filaments. These filaments have many functions including the transfer of ions and water, as well as the exchange of oxygen, carbon dioxide, acids and ammonia.
gills
superclass of jawless fish in the phylum Chordata, subphylum Vertebrata, consisting of both present and extinct species. The group excludes all vertebrates with jaws, known as gnathostomes.
Jawless Fishes
class that contains the cartilaginous fishes: they are jawed vertebrates with paired fins, paired nares, scales, a heart with its chambers in series, and skeletons made of cartilage rather than bone.
cartilaginous fishes
popularly referred to as the bony fish, is a diverse taxonomic group of fish that have skeletons primarily composed of bone tissue, as opposed to cartilage.
Bony Fishes
is an internal gas-filled organ that contributes to the ability of a fish to control its buoyancy, and thus to stay at the current water depth without having to waste energy in swimming.
Swim Bladder
Amphibians are ectothermic, tetrapod vertebrates of the class Amphibia. Modern amphibians are all Lissamphibia.
Amphibians
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
lungs
breathing through gills and lacking legs until its later stages of development.
tadpole
The Metamorphosis is a novella by Franz Kafka, first published in 1915. It has been called one of the seminal works of fiction of the 20th century and is studied in colleges and universities across the Western world.
Metamorphosis
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.
Salamanders
Frogs are a diverse and largely carnivorous group of short-bodied, tailless amphibians composing the order Anura
frogs
A toad is any of a number of species of amphibians in the order Anura that are characterized by dry, leathery skin, short legs, and parotoid glands
toads
Reptiles are a group of tetrapod animals comprising today’s turtles, crocodilians, snakes, amphisbaenians, lizards, tuatara, and their extinct relatives.
reptiles
They are distinguished from the anamniotes, which typically lay their eggs in wate
Amniotic Eggs
Testudines characterised by a special bony or cartilaginous shell developed from their ribs and acting as a shield.
turtles
of land-dwelling vertebrates in the order Testudines. Tortoises are shielded from predators by a shell.
Tortoises
Crocodylinae, all of whose members are considered true crocodiles, is classified as a biological subfamily
Crocodiles
An alligator is a crocodilian in the genus Alligator of the family Alligatoridae.
alligators
elongated, legless, carnivorous reptiles of the suborder Serpentes that can be distinguished from legless lizards by their lack of eyelids and external ears
snakes
Lizards are a widespread group of squamate reptiles, with approximately over 6,000 species, ranging across all continents except Antarctica, as well as most oceanic island chains
