Reptiles
Habitat:
Modern reptiles live on in virtually every biome of every continent, excluding Antarctica.
Milestones:
Legs, vertebrae, hollow nerve tubes
Anatomical Features:
-Heart- the same for all reptiles, but the way of mixing oxygenated and not oxygenated blood differs by species.
-Lungs- all reptiles breath using lungs
-Skin- horny skin that keeps in water to allow reptiles to live on land
Eating and Fleeting:
Most are carnivorous heterotrophs that have relatively simple and fast digestive systems, though slower than humans.
Symmetry:
Bilateral
Mobility:
Most move by walking, but some, like snakes, use muscle contractions to slither.
Reproduction:
Reptiles reproduce sexually, and all reproductive activity is done through the cloaca. Reproductive organ are usually inverted or can be retracted inside of the body. In some species of lizards, asexual reproduction is possible.
Development:
There are no larval stages of development, so they are born as smaller versions of their mature selves.
Examples:
-Sphaerodactylus ariasae
-Megalania prisca
-Malpolon monspessulanus
Other Information:
-Some reptiles have TDSD (Temperature-Dependent Sex Determination) in which the incubation temperature affects the gender of the offspring.
