Document Summary
Sequence of live events in an organism. (growth/development/reproduction/death) we are interested in all of these factors. For a human, you go through a period of growth and then you reproduce. Our perception of life history is biased based on our experiences. However, many organisms experience very different life histories. Life history characteristics include: age and size at sexual maturity, amount and timing of reproduction, survival and mortality rates. Clown fish hang in sea anemones for protection. Anemones sting the predators of clownfish, but not the clownfish themselves. The fish also benefit the anemone by eating its parasites or driving its predators away. Usually 2-6 will hang out in one sea anemone for their entire adult lives. However, it is unlikely that they are related. They are simply biting their time waiting for the others to die off so that they can take their place. (based on body size) in finding nemo, his mom died.
