Amphibian. What is an Amphibian?. Vertebrate Live in the water as larva and on land as adults Breaths w/ lungs Moist skin with mucus glands Lacks scales and claws. Evolution of Amphibians. Movement: stronger bones and limb girdles Breathe Air: lungs & breathing tubes
Amphibian. Salamander. Amphibians Class. All amphibians are cold-blooded. Amphibians live in each continent except for Antarctica. An average amphibian grows smaller then other vertebrates. Salamander Adaptation.
Amphibian ADAPTATIONS. Ms. Bridgeland 5 th Grade. Stage 1 : Adult frogs. Stage 2 : Frogs lay eggs in water, which then are fertilized. . *How are Amphibian Eggs different from other eggs? -They do NOT have a shell, but instead a jelly-like protective coating.
Amphibian Taxonomy. Amphibian Basics. Ectothermic vertebrates 3 Chambered heart Glandular Skin Cryptic Scaleless. Metamorphosis. Aquatic to land Primary Changes: -Legs -Lungs -Eyes -Tail (anurans) -Skin. http://www.dnr.state.md.us/wildlife/art/tadpole-to-frog.gif.
Amphibian Digestion. Amphibians include frogs, toads, salamanders, newts, & caecilians. Amphibians most likely evolved from the lobe-finned fishes, so their digestive systems are also similar. Mouth. Contains maxillary and vomerine teeth. Tongue attached at the front of the mouth .
AMPHIBIAN NOTES. EXTERNAL STRUCTURE AND MOVEMENT. Amphibian skin does not have scales , feathers, or hair . It does have secretions that help with protection. These glands also keep skin moist to prevent drying. They also produce toxic chemicals that discourage potential predators.
Amphibian Diseases . In amphibians bacterial infections are commonly caused by gram-negative bacteria, such as Aeromonas , Pseudomonas, Proteus, and E. coli.
AMPHIBIAN METAMORPHOSIS. METAMORPHOSIS :- the transition from a larval stage to an adult stage. MORPHOLOGICAL CHANGES ASSOCIATED WITH METAMORPHOSIS :- In amphibian, habitat changes from aquatic to the terrestrial. In urodeles (salamander):- These changes include the
Amphibian Diversity. Some observations on the origins and diversity of the Amphibia. Extant Amphibia. There are 3 groups of extant amphibians: Urodeles, Anurans, and Gymnophiona. ( Ambystoma maculatum ). Amphibia.
