Evolutionary Milestones
Mammals posses nine evolutionary milestones: eukaryote, tissues, bilateral symmetry, body cavity, enclosed body cavity, hollow nerve tube, backbone, legs, and hair.
Habitat
Mammals can be found all over the world. Even in the ocean.
Anatomical/ Structural Features
Mammals have a backbone, legs, hair, and mammary glands. Their respiratory system includes a diaphragm and lungs. They have teeth and some have opposable thumbs. They have a complex nervous system and senses. Also the have sweat, oil, and scent glands.. Their heart has four chambers.
How do they acquire nutrients
Mammals are heterotrophs. They can be a herbivore, carnivore, or an omnivore.
What do they eat
Mammals eat kind of everything. They eat anything from plants, fish, amphibians, other mammals, fungi, and many more.
What eats them
Predators of mammals include other mammals, large reptiles, fish, and birds.
Symmetry
Mammals have bilateral symmetry.
Mobility
Mammals use their legs to walk/crawl. Some mammals swim.
Reproduction
Mammals reproduce sexually by internal fertilization.
Development
This is the life cycle of a mammal: 1. embryo, 2. newborn, 3. juvenile, 4. adult.
Other Information
Mammals have the ability to learn. Mamma means breast. Mammals are warm blooded.
