Document Summary
An organism"s life history is a record of events relating to its growth, development, reproduction, and survival. Life history characteristics include age and size at sexual maturity, amount and timing of reproduction, survival and mortality rates. The timing and nature of life history traits are products of adaptation to the environment in which the organism lives. Nemo grows up case study: clownfish spend their entire adult lives within a single sea anemone. The anemone protects the clownfish by stinging their predators, and the clownfish help the anemone by eating its parasites or driving away its predators. In real life, two to six clownfish spend their entire adult lives within one sea anemone, but they are usually not related. There is a strict pecking order in the group, based on body size. If the female dies, the breeding male becomes a female, and the next largest fish becomes the breeding male.
