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. There are an additional 41 Halobates species in sheltered, coastal marine waters throughout the tropical Indo-Pacific. After being largely ignored by biologists for decades, sea skaters have recently become much better known and their taxonomy, phylogeny, biology, ecology, and biochemistry have been widely studied.
