Question Set: Adaptations

  1. The following are all real strategies used by fishes living in extreme environments.
    Predict the habitat that this strategy might be effective in and explain your prediction.
    1. Anglerfish males are very small. They find a femail and become parasitic, with the male’s blood system becoming part of the female. She feeds him through their joined blood systems, and in return he provides sperm for her eggs. Neither reach sexual maturity (to save energy) until they are joined.
    2. Lungfish aestivate (a state similar to hibernation) in a mudball.
