abstract = {A total of 114 marine mammal records of 14 species were compiled from Iranian coastalwaters of the Persian Gulf and Gulf of Oman. Eighty-one were from the Persian Gulf, 23from the Gulf of Oman and 10 were of unknown location. Records of finless porpoise(Neophocaena phocaenoides) (24), Indo-pacific humpback dolphin (Sousa chinensis) (22)and Indo-pacific bottlenose dolphin (Tursiops aduncus) (21) were by far the most numerousa probable reflection of their inshore distribution and local abundance. Other speciesrecorded were common dolphin (Delphinus capensis tropicalis), rough-toothed dolphin(Steno bredanensis), striped dolphin (Stenella coeruleoalba), spinner dolphin (Stenellalongirostris), Risso's dolphin (Grampus griseus), false killer whale (Pseudorca crassidens),sperm whale (Physeter macrocephalus) and dugong (Dugong dugon). Records of 24Mysticetes were compiled, 11 of which were tentatively identified as Bryde's whales(Balaenoptera edeni), three as Fin whales (Balaenoptera physalus), three as Humpbackwhales (Megaptera novaeangliae) and the remainder were unidentified. The largest threat tomarine mammals in Iran is likely to be incidental capture in fishing gear. Nine finlessporpoises were recorded as bycatch and this and other coastal species may be declining dueto unsustainable mortality rates. Other threats to the marine environment are discussed andrecommended marine mammal conservation and management small projects are described.},

abstract = {The annual migrations of baleen whales are a conspicuous, but unexplained feature of their behavioural repertoire.  Some hypotheses offered to explain whale migration focus on direct benefits to the calf (thermoregulation, calm water) and some do not (resource tracking, and the "evolutionary holdover" hypothesis).  Here we suggest that a major selective advantage to migrating pregnant female baleen whales is a reduced risk of killer whale predation on their newborn calves in low-latitude waters.  Killer whale abundance in high latitudes is substantially greater than that in lower latitudes, and most killer whales do not appear to migrate with baleen whales.  We suggest that the distribution of killer whales is determined more by their primary marine mammal prey, pinnipeds, and that following the baleen whale migrations would remove them from their pinnipeds prey. There are problems with all current hypotheses, most of which stem from a lack of directed research.  We explore variation in migratory habits between species, populations, and individuals that may provide a "natural laboratory" for discriminating among the  competing hypotheses.  The authors specifically recommend more detailed study of non-migrating populations, such as the Arabian Sea population of humpback whales.},
