|Scientific Name:||Megaptera novaeangliae (Arabian Sea subpopulation)|
|Species Authority:||(Borowski, 1781)|
No subspecies of
the humpback whale are recognized. The worldwide population is divided into
three major oceanic divisions based on genetic differentiation:

232 cm) of 36 examined fetuses indicated calving commencing in December, with a
peak in February. Mikhalev (2000) suggested a 3-4 month mating season lasting
from January to May, coincident with that of other Northern Hemisphere
populations. Females with calves have been observed on the Arabian Sea coast of

Humpback whales are well-known to be susceptible to entanglement in
fishing gear (Volgenau et al. 1995,
Johnson et al. 2005). A total of nine
humpback whale entanglements in fishing gear have been recorded off the coast
Humpback whales have been legally protected from commercial whaling
in the southern hemisphere since 1963, and the
The potential for successful conservation of humpback whales in the region is considered to be high, provided that range state governments are made aware of this population’s precarious status. The countries of the Arabian region are generally affluent and in a good position to implement marine conservation measures for humpback whales in addition to those already initiated for other taxa, such as sea turtles. A coordinated series of marine protected areas, combined with species-specific protection measures, could greatly enhance the long-term prospects for humpback whales in the region.
