Animals and Behavior
Term | Definition |
---|---|
Innate | Behavior that is influenced by genes, NOT by learning or experience. Born with it. |
Learned | Behavior that have been learned from experience or observing other animals |
embryo | An organism in the early stage of development |
estivation | A period of reduced activity some animals experience in the summer. |
biological clock | an internal control of natural cycles |
tissues | similar cells that work together to perform a specific job in the body |
organ | combination of 2 or more tissues |
communication | takes place when a signal travel from one animal to another and the receiver responds. |
pheromones | chemicals animals produce for communication |
invertebrates | an animal without a skull or backbone |
navigate | to find ones way from one place to another. Using Landmarks, sun and stars, and Earth's magnetic field. |
consumer | organism that eats other organisms |
camouflage | coloration and/or text that enables an animal to blend in with its surroundings. |
landmarks | a fixed object an animal uses to find its way |
circadian rhythms | daily internal patters such as migration and mating |
vertebrates | animal with a skull and a backbone |
territory | an area occupied by an animal or a group of animals from which other members of the species are excluded. |
social behavior | this type of behavior is the interaction between animals of the same species |
predator | an animal that eats other animals |
multi-cellular | made of many cells |
hibernation | period of inactivity that some animals experience in the winter |
prey | an animal that is eaten by another animal |
animals | - invertebrates 97% or vertebrates 3% - many cell or multi cellular - reproduce by sexual reproduction - develop from embryo - specialized body parts - cells form tissues form organs form organ systems - movement - most animals move from place to pl |
invertebrates | porifora cnidaria Platyhelminthes nematoda annelida Echinodermata Mollusca arthropoda |
vertebrates | jawless fish cartilaginous bony amphibians reptiles birds mammals |
Survival - How do animals survive? | Find food Find water Avoid being eaten Find Shelter |
mimicry | imitate something in nature, often something more dangerous |
warning coloration | bright colors to signal "danger" |
Animals defense | sharp teeth, claws, speed, chemicals, toxins, warning defense |
torpor | slowed heartbeat, lower temperature, slower metabolism (hibernation, estivation) |
Why do animals migrate? | travel to one place to another to find food, water and safe nesting grounds. Whales, Salmon, bats, monarch butterflies |
