ABSTRACT

 

This ethogram describes the basic behavioral repertoire of the common Indo-Pacific mudskipper Boleophthalmus boddarti (Pallas). The population found on the mudflats of Sulaibikhat Bay, Kuwait was studied and is composed of territorial individuals of both sexes which build and defend mud-walled polygonal territories, and smaller, errant or non-territorial individuals. The mudskippers non-social and maintenance behaviors including feeding, thermoregulatory responses and wall construction behavior is described. The basic formations, fin and head positions during both agonistic and courtship display behavior are also described. The behavior of the errant individuals is similar to that of the territorial fish except that they do not engage in construction or male courtship activity. The activity of Boleophthalmus boddorti is highly seasonal being correlated with the considerable seasonal and daily changes in temperature. Many of the fishes maintenance behaviors can be explained in terms of adaptation to an amphibious way of life under such conditions. Other behavior patterns found in agonistic and courtship behavior can be interpreted as adaptations to selection pressures exerted on substrate-bound fish. Some of the problems in reproductive biology presented by the unique territorial mosaic social system of B. boddarti are mentioned.
