The Animal Kingdom Over 1 million species

Two Major Categories of Animals Vertebrates - have a backbone - includes fish, amphibians, reptiles, birds, and mammals - less than 5% of all known animals are vertebrates Invertebrates - no backbones - includes bugs, sponges, worms, mollusks, and many more http://www.brainpop.com/science/livingsystems/vertebrates/ http://www.brainpop.com/science/livingsystems/invertebrateshttp://www.brainpop.com/science/livingsystems/invertebrates/

Characteristics of Animals Multicellular No cell walls Usually sexual reproduction Develop from embryos Specialized parts – tissue, organs etc.

Animals Chapter 1 section 2
11
Animal Behavior Survival Seasonal
12
Survival - Defense Animals co-evolve as a response to one another Some animals have horns, some have chemicals, some are poisonous Warning coloration – colors of animals can warn of poisons or give the appearance of poison – reds, yellows, oranges, black, white Camouflage – blending into the background Puffing up – animals will make themselves appear bigger ex. Scared cat
13
Survival – Necessities Animals use tools – ex- birds can open ostrich eggs with rocks, apes use sticks to get food etc. Animals build shelters – ex. Rodents, birds etc.
14
Nature versus Nurture Innate Behavior (nature) – genetic predisposition to certain types of behavior ex. Puppies chew, worms burrow. These are behaviors that do not need to be taught. Learned Behavior (nurture) – behavior that has been learned through experience or from watching other animals
15
Nature or Nurture?
16
Eagle Mother and Babies
17
Seasonal Behavior Migration – for food, mating, warmth- use landmarks and earth’s magnetic field to navigate Hibernation- inactivity where organism will slow heart rate, decrease body temperature, slow breathing rate to the extreme. Do not wake for weeks. Ex- mice, squirrels Winter sleep- similar to hibernation but not as extreme Ex- bears Estivation – internal slowdown during hot months when resources get scarce ex- desert rodents
18
Rhythms Biological clocks – internal control of natural cycles. Can happen daily or over a lifetime. Circadian Rhythms – daily biological clocks ex – nocturnal versus diurnal
19
Animals - Living Together Chapter 1 section 3
20
Social Behavior Interaction of animals between the same species Requires communication
21
Communication A signal must travel from one organism to another and the receiver must respond Animals communicate to defend territory, courtship, warn of trouble and friendship
22
How Do Animals Communicate? Verbal Smell – Pheromones:chemicals are released to warn of trouble, for mating purposes, recognition Body language Touch
23
Living in a Group-Good and Bad Good Safer – they can defend one another Cooperation – they can help one another find food, shelter etc Bad Attract predators More competition
