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 article and the lecture both deal with how humpback whales migrate long distances. Whilst the author claims that humpback may navigate by the stars and proposes three possible reasons for support, the lecturer contradicts his arguments respectively.
First , according to the reading humpback whales have high intelligence which provide the ability to use the stars for navigation. In contrast, the professor argues that they are not actually connected, because other animals like ducks also use the stars to navigate but they have average intelligence.
Second, the author states that humpback migrate in straight direction relying on stars as there is no landmarks they can use. However, the speaker questions this argument by saying that humpback whale may use earth magnetic field to maintain direction instead of stars as they have a biomagnetide within their body.
Lat but not least, the writer posits that humpback whales can use star to navigate through a behavior call spy-hopping. As apposed to the author, the lecturer points out that other animals like sharks also exhibit spy-hopping behavior, but they do not migrate, they use it to hunt instead. Furthermore, she adds that sharks usually exhibit this behavior at day time when stars can not been observed.
As we can see the author and the lecture hold very different views on humpback whales.
