Mammals
Habitat:
Some mammals live on land while others live in water (they can live almost anywhere)
Reproduction:
Sexual internal fertilization
Anatomical Features:
1. Endotherms (warm-blooded)
2. Milk to feed young from breasts
3. Respiratory system includes a diaphragm and lungs
4. Teeth are modified according to the type of food(s) eaten
5. Limbs are modified with things such as an opposable thumb
6. The nervous system and senses are complex
7. Four chambered heart with closed circulatory system
Evolutionary Milestones:
Hair
Predators/Prey:
- Herbivores, omnivores, and carnivores
Predators: Birds, other mammals, reptiles, amphibians, fish, mollusks, harmful strains of fungi and bacteria, and other organisms
Symmetry:
Bilateral symmetry
Mobility:
Will depend on specific organism, some have legs while others are in marine environments and use flippers or fins to move
Development:
Fertilized egg/zygote, blastula, embryo, adult
