Like many creatures, humpback whales migrate long distances for feeding and mating purposes. How animals manage to migrate long distances is often puzzling. In the case of humpback whales, we may have found the answer: they may be navigating by the stars, much as early human sailors did. What we know about humpback whales makes this a distinct possibility.
First, humpback whales seem to be intelligent enough to use stars to navigate by. Whales' brains have a high degree of complexity -- a common determiner of intelligence. This suggests that the whales' brain power far exceeds that of most other animals. The whales' well-developed cognitive ability seems to provide a sound basis for the ability to use a complex, abstract system of sensory stimuli such as the night sky for orientation.
Second, humpback whales migrate in straight lines. Animals can maintain movement in a straight direction for long distances only if they orient themselves by some external objects or forces. Many birds and other terrestrial creatures, for example, use physical landmarks to help them stay on track as they migrate. Whales, which swim in the open ocean, cannot rely on land features; they could, however, rely on stars at night to provide them with external signs by which to maintain direction over long distances.
Third, humpback whales exhibit an unusual behavior: they are sometimes observed floating straight up for minutes at a time, their heads above the water as though they were looking upward. The behavior is known as spy-hopping, and it is very rare among marine animals. One explanation for the function of spy-hopping is that the whales are looking at the stars, which are providing them with information to navigate by.
the reading states that humback whales for long distance migration, they would navigated by stars and provides three reasons of support. The lecturer, however, challenges the claims made by the author. He explains that none of these claims are convincing and refutes each of the author's claims.
First of all, the author argues that humback whales have enough cognitive ability seems to provide
a sound for use a complex, anstract system of sensory stimuli. In addition, the whales has a enough
intelligence to use star for navigation. this specific argument is challenged by the lecturer. He says that there is no connection between intelligence and navigational ability. The lecturer elaborate on this point by says that other animal-like duck use star for their navigational purpose but they are average intelligent and most interesting thing is that their navigational power is inherent and not to present their intelligence. hence whales' intelligence and their navigational power seems do not connected.
secondly, the author of the reading states that humback whales migrate in straight lines
and they oriented themselves on stars at night to provide them with external signs by which to maintain direction over long distance. the lecturer, however, rebuts this claim that whales have a biomagnetic field and their magnetic field are very sensitive of earth magnetic field. thus their external forces are likely to be earth magnetic fields which they rely on for their long-distance rather than stars.
Finally, the author posits that humbacks have a unusal spy- hopping behavior and whales are looking at the stars, this procedure providinig them with information to navigate them. in contrast, the lecturer position is that this behavior also present others aimal like shark but shark to show this
behavior for hunting animal. moreover, the lecturer says that humbacks this behavior also present their other purpose rather than navigational purpose. hence, this spr hopping bevior's of humback for their navigation is completely speculating.
