Document Summary
Possible social behaviors based on the effects of relative fitness of 2 interactants. Cooperation: your behavior increases your fitness and the fitness of others. They may successively pounce, relay attacks, or some flush prey out of hiding so others can attack. Cooperative hunting with black-banded sea krait and yellow goat fish and trevally fish. Cooperative courtship in the long-tailed manakin females are courted by dominant and subordinate male. 2 males better than 1: dominant male has a long-term mate while the subordinate male can copulate when dominant male is absent or can take over if dominant male dies. Blue manakin birds work in teams to dance for a female. Alpha male is team leader and gets to copulate. Elephant cooperation task: both elephants must pull their ropes to move a platform to obtain a food reward. Delayed release of elephant, so the first elephant waits for second to arrive. Selfish: your behavior increases your fitness, but doesn"t increase others.
