invertebrates : animals without backbones.
The bodies of invertebrates are covered with exoskeletons
Exoskeleton : hard or tough outer coverings that provide a frame work of support
An endoskeleton is a skeleton found within the interior of the body
it provides structural support and protection for the internal organs and tissues of an organism
vertebrate : an animal with a backbone
The evolution of nerve and muscle tissues enables animals to move in ways that are more complex and faster than organisms in other king- doms.
ex: mosquito buzzing around your
gecko running across a ceiling,
Some animals are stationary as adults, yet most have a body form that can move during some stage
Animal bodies have a variety of adaptations, such as those for feeding, digestion, and support. These body variations enable animals to live in numerous habitats
Vertebrates and invertebrates live in oceans, in freshwater, and on land. They can be found in deserts, grasslands, rain forests, polar regions, and all other land biomes and aquatic ecosystems.
most animals reproduce sexually
some animals are hermaphrodites, meaning they produce both sperm and eggs n the same body.
fertilization occurs when the sperm penetrates the egg to form a fertilized egg called the zygote.
Fertilization can be inter- nal or external. Internal fertilization occurs when the sperm and egg combine inside the animal’s body
External fertilization occurs when egg and sperm combine outside the animal’s body
feeding on digestion lama
Animals are heterotrophic, so they must feed on other organisms to obtain nutrients
ex: like a butterfly feeds on nectar from a flower
You can investigate how some animals obtain food by performing .After obtaining their food, animals must digest it. Some animals, such as sponges, digest their food inside specific cells.
