CLEANING SYMBIOSIS
What traits do they share?
Interactions between organisms can influence the traits and behaviors
of those organisms
RELATIONSHIPS IN THE OCEAN
ReproductionMale-Male interactions influence male sizeMale-Female interactions influence male courtship behavior &
traits used in display male lifestyles
ParasitismHost-parasite interactions influence traits parasites use to “control” hosts behaviors hosts use to avoid parasites…
MutualismInteractions that can help some species
avoid other interactions!
