22 Rhizocephalan barnacles

23 lands externally burrows in grows internally: interna stage impedes growth feminizes male grows internally: interna stage impedes growth female Parasitic Barnacle Life Cycle externa opens infect new crab produces externa stage reproductive replacement.. castration

25 CLEANING SYMBIOSIS

26 What traits do they share?

27 Interactions between organisms can influence the traits and behaviors of those organisms RELATIONSHIPS IN THE OCEAN 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!
