Two Male Parasitism Female Anglerfish Which one is a barnacle? A B C E=all of the above F=some of the above D Rhizocephalan barnacles Parasitic Barnacle Life Cycle lands externally burrows in infect new crab male female grows internally: interna stage impedes growth feminizes grows internally: interna stage impedes growth externa opens produces externa stage reproductive replacement.. castration What is this shrimp doing?? A. B. C. D. becoming lunch committing suicide having lunch making a mistake CLEANING SYMBIOSIS What traits do they share? RELATIONSHIPS IN THE OCEAN Interactions between organisms can influence the traits and behaviors of those organisms Reproduction Male-Male interactions influence male size Male-Female interactions influence male courtship behavior & traits used in display male lifestyles Parasitism Host-parasite interactions influence traits parasites use to “control” hosts behaviors hosts use to avoid parasites… Mutualism Interactions that can help some species avoid other interactions!
