Chapter 11: fishes, amphibians, reptiles Flashcards
Nerve Cord
A structure connecting the brain of an organism to the nerves that run throughout the body
Vertebrate
an internal skeleton that supports the body and allows it to move
backbone
runs down the center of the vertebrates back
internal skeleton
bone structures that give the body shape, protects the internal organs, and allows for easy movement
Ectotherm
an animal whose body does not produce much internal heat
Endotherm
an animal whose body regulates its own temperature by controlling the internal heat it produces
Fish
a vertebrate that lives in the the water and uses fins to move, and it uses gills to breathe
Amphibian
A vertebrate that is ectothermic and spends its early life in water
Tadpole
The larva of a toad or frog
Lungs
Organs of air breathing vertebrates in which oxygen and
carbon dioxide are exchanged between the air and the blood
Habitat
the environment where a plant or animal naturally lives and grows
Amniotic eggs
An egg with a shell and internal membranes that keep the embryo moist
What phylum do chordates belong to?
phylum Chordata
what adaption do fish have for movement
fins
what are the function(s) of an internal skeleton
- Protects the internal organs of the body.
- Gives the body shape.
- Acts as an internal frame that supports the body against the downward pull of gravity.
- Gives the muscles a place to attach to.
- Allows for easy movement
name two examples of ectothermic and endothermic creatures
ectothermic = polar bears, humans, dogs, (most mammals)
Endothermic = Snakes, skinks, lizards (most reptiles or amphibian)
how do fish get oxygen?
gills
what are the 3 types of fish
boney, cartilaginous, and jawless
what is metamorphesis and how does it apply to amphibians
metamorphesis is the transition from immuture to adult forms. amphibians undergo metamorphesis so the can live on land
what are the 4 points of a frogs development
egg, tadpole, metamorph, adult
what are two ways amphibians get oxygen?
lungs and they absorb it through their skin
why are amphibians in danger?
habitat loss and pollution
what are the three types of amphibians
frogs, toads, salamanders
what are the four main reptiles we talked about in class?
snakes, turtles/tortise, Crocodylidae, lizards
how do you tell crocs and aligators apart
crocs have a pointed and thin snout, aligators teeth will not show, coloration
compare and contrast lizards, snakes, turtles and crocodilians
all are reptiles, snakes and lizards are similar in that they both have overlapping scales and are carnivouris, lizards have legs but snake do not. turtles are unquies becuase the have a hard, protective shell, while crocadilians have long, toothy snouts.
list 4 types of the 4 main reptiles?
lizards = blue tongue skink, monitor, komodo dragon
crocodilians = alliagtor, crocs, camien
Turtles/ tortise = sea turtle, snapping turtle, red slidder
snakes = cobra, constrictor, viper
