The evolutionary success of insects on land is unparalleled among the metazoans. Although many insects occur in marine habitats, the only oceanic habitat colonized by insects is the sea-air interface.

Five species of sea skaters or ocean striders, genus Halobates (Hemiptera- Heteroptera, Gerridae) are widespread in tropical oceans and both adults and juveniles spend their entire lives on the sea surface.
