 The pigeye shark is a largely solitary animal, though occasionally several individuals may be found at the same location.In the Mozambique Channel, it outnumbers the bull shark on the east side while the opposite is true on the west side, suggesting there may be competitive exclusion between these similar species.Parasites documented from the pigeye shark include the myxosporean "Kudoa carcharhini", the copepods "Pandarus smithii" and "P. cranchii", and the tapeworms "Callitetrarhynchus gracilis", "Cathetocephalus" sp., "Floriceps minacanthus", "Heteronybelinia australis", "Otobothrium australe", "O. crenacolle", and "Protogrillotia" sp.
