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 and lecture are both about humpback whales who use to migrate in long distance. The author of the reading feels that they nused several strategies for migration especially navigation through the star. However, the lecturer challenged the claim made by the author. He is on the opinion that navigation using star is quite fascinating but not convenient.

To begin with, the author argues that humpback whales are quite intelligent than the other animal. He also mentions that their brain supports cognitive ability that helps them to navigate using star. The specific argument is challenged by the lecturer. He states that intelligent does not means that they could navigate. He also elaborates the point by bringing that some dogs are intelligent too but there is no evidence that they could use the star for their direction.

Second, the writer suggests that humpback whales are migrated through even lines. He also adds that some animals migrate by identifying the landmarks but humpback whales possibly can not do that because they swim in the open ocean and that's why they use star. However, the lecturer rebuts this by mentioning evidence shows that they have a bio-magnetic organism that helps them to identify the direction. He also claims that by using bio-magnetic organism they can sense the force of the external objects.

Third, the author posits that humpback whales have erratic behaviour like spy-hopping which is not shown to other animals. By using this technique they actually looking for stars for direction. In contrast, the author position is that some sharks used to migrate using this technique and they use it for hunting. He also mentions that the author should not assume it for the humpback whales.
