Ecological Fitness How well an organism has adaptations well suited to its environment An ecologically fit organism has a survival advantage Adaptation An inherited characteristic that increases an organisms ability to survive an environmental change. Taxonomy of Amphibians. Kingdom . Animalia. Phylum . Chordata. Subphylum Vertebrata. Class . Amphibia. Order . Urodela. . (salamanders & newts). Order . Anura. . (frogs & toads). Amphibian diversity.

Lizards, snakes, and worm lizards. Which of the following traits is shared by all vertebrates, at least in some developmental stages, except the lampreys?. notochord. vertebrae. cartilaginous skeleton. cranium (head). mouth with jaws. Fully adapted for life on land. All Amniotes – produce Amniotic Eggs. Dry, Scaly Skin. Ectothermic . More Efficient Circulatory and Respiratory Systems. Cloaca . Except for snakes, Reptiles have Paired limbs, most ending in 5 clawed toes . Adaptations to Meet Challenges of Life on Land. Challenges of Life on Land vs. Water. Adaptation to Meet Challenge . Air much less buoyant than water so must move against gravity. Limbs develop;. skeletal and muscle systems become stronger. How many animals are there?. Rainforests have more animals than any other ecosystem!. There are 125 . species of mammals, 400 species of birds, 100 species of reptiles, 60 species of amphibians, and 150 species of .
