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 discussion is mainly about whether humpback whales leverage the star as a way to navigate their long-distance migration. The article provides three reasons to support the statement while the lecturer disagrees what has been presented in the article. I will elaborate on details in the following essay.
To begin with, the article mentions that the whales have high intelligence for them to be capable of using star to navigate their journey. However, the professor refuses the statement since there is no real connection between the intelligence and star navigation. He uses duck as an example, in that ducks are also capable of using star to navigate the way but their intelligence is only average, and what makes them able to do so is the distinct they are borned with. This example manifests that no correlation between brain power and star navigation.
Additionally, the article states that it is essential to have external objects, such as the star, to achieve a straight-line migration. Again, the professor counters the opinion and he provide an alternative explanation is that the whales can use the maganectic feel to achieve the same result. He further expresses that the whales are sensitive to the bio-magnectic change of the earth and this makes the magnectic navigation more possible than star navigation.
Last, the article talks about the spy-hopping to demonstrate the whales’ behavior of looking for the star for navigation. The professor holds different beliefs of the spy-hopping bahvior for two reasons. First is that the shark also has the same bahvior but the motivation behind is looking for animal to hunt instead of navigation. Secondly, the whales normally do the spy-hopping during the day, which is difficult to see the star. Therefore, it is not reasonable to conclude that the spy-hopping behaviour is for star navigation.
To sum up, due to the lack of connection between the intelligence and the star navigation, and the alternative possibility of magnectic navigation, as well as the motivation of hunting behind the spy-hopping bahavior, it is unlikely that the whales do use star to navigate their journey.
