The crookback Whale (Megaptera novaeangaliae) is a life-sized baleen giant star species who has populations in most major oceans (Simona L. Perry, 1999). In this essay, Southern hemisphere Humpback whale population stocks will be analysed, including biological aspects that will help to explain their basic physiology and behaviour. Southern Humpback Whales display specialised behaviour and physical attributes that maximise their top executive to survive in their natural habitat. However, know guidege of these factors invite allowed hunters to crop the whales specific behaviour approach patterns, particularly with the distribution of stocks, which has led to large scale population crashes in Southern Humpback Whales (Findlay, 2001). This has led to attempts in conservation methods to protect this vulnerable species.
Humpback Whales have features in their physiology that are characteristic in their appearance. For example, they are relatively heavier than other whale species at up to 60 tonnes, at a body length of 15 metres (McGonigal & Woodworth, 2005). Humpbacks show revoke sexual dimorphism, with females creation larger in size than males.
organism a Baleen whale, the Southern humpback whale has no teeth, instead possessing baleen plates (Trewby, 2002) which filter smaller prey, with Antarctic krill(euphasia superba) being their primary source of food (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 singing whales (McGonigal & Woodworth, 2005). The males have developed composite low frequency songs which can 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 between habitat zones depending on their situation.
