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.
In the reading passage, the author discusses three kinds of the reason the support the idea that Humpback whales use stars during their migrate, while the lecturer claims that what the reading passage states is not convincing and disputes those reasons presented in the reading passage bu several proofs.
First, both the text and the talk discusses about Humpback whales intelligent. In this regard, the belief in the reading passage is that Humpback whales are more powerful than other animals and so intelligence to use stars during the migration. However, the speaker views to this issue is from an opposite angle. According with the speaker, there is no relationship between the intelligent and the ability of using start for navigation. Also, mentions to the bird spices which migrate by using stars event though are intelligent.
Second, both the reading and listening material put forth the idea of the straight line migration of Humpback whales. In this vein, the author states that animals can navigate in straight line only when they orient themselves by some external objects or forces such as birds which use the landmark to track their ways and in the open ocean environment the best way is the using of start. On the other hand, the lecturer admit that some external object or force stimulate Humpback whales to migrate in straight line, but refutes the using stars to explan this phenomenon. The lecturer says that Humpback whales maybe able to use earth magnetic field. Because of the bio magnetized which id detected in the Humpback whales brain, this animals maybe able to use earth magnify.
Third, the writer make point to the idea that Humpback whales unusual behavior like looking to the upward and writer think by this way they use the star to continue their ways. By contrast, the lecturer take shark as an example which is do this behavior to find the author animal for eating. Beside, Humpback whales show this behavior in the day when there is no star in the sky.
