Oedoparena
Oedoparena is a small genus of flies in the family Dryomyzidae, comprising three known species. It is the only known dipteran genus whose larvae prey on marine barnacles. These flies function as intertidal mesopredators with documented ecological impacts on high intertidal community structure.
Ramphocorixa
Ramphocorixa is a genus of water boatmen (Corixidae) established by Abbott in 1912, containing at least two described species. The genus includes a notable marine species, R. balanodis, which exhibits extreme morphological adaptations for feeding on barnacles in saltwater intertidal habitats—unusual for a family predominantly found in freshwater. Most species occur in freshwater lakes and ponds across North, Central, and northern South America.
