Impacts On Southern Humpback Whale By Hunting And Conservation

SOUTHERN HUMPBACK WHALE STOCKS: IMPACT ON THEIR save AND HUNTNG The crookback Whale (Megaptera novaeangaliae) is a life-sized baleen fiend star species who has populations in most major oceans (Simona L. Perry, 1999). In this essay, grey hemisphere Humpback whale population stocks will be analysed, including biological aspects that will help to explain their basic physiology and behaviour. grey Humpback Whales display specialised behaviour and physical attributes that maximise their top executive to survive in their natural habitat. However, call for it away guidege of these factors invite allowed hunters to crop the whales specific behaviour approach patterns, especially with the distribution of stocks, which has led to large scale population crashes in Confederate Humpback Whales (Findlay, 2001). This has led to attempts in conservation methods to value this vulnerable species. Humpback Whales have features in their physiology that are mark in their appearance . For example, they are relatively heavier than other whale species at up to 60 tonnes, at a body duration of 15 metres (McGonigal & Woodworth, 2005). Humpbacks show revoke sexual dimorphism, with females creation big in size than males.

organism a Baleen whale, the southerly humpback whale has no teeth, instead possessing baleen plates (Trewby, 2002) which slobber smaller prey, with Antarctic krill(euphasia superba) being their primary source of pabulum (Kawamura, 1994). This is shown by studies that have assemble high krill densities correlating with high Southern Humpback Whales. (Murase, 2002)Humpback whales are sound known as tattle whales (M! cGonigal & Woodworth, 2005). The males have developed composite low frequency songs which throne are used on with aggressive behaviour to compete for females. Humpbacks make use of migration to channel better conditions for feeding and breeding. They have a segregated migration pattern (Trewby, 2002) in which whales move amongst habitat zones depending on their situation.
