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 passage suggests different probable reasons due to which humpback whales can cover great distances by navigating the stars. However, the lecture did not agree with the concepts and therefore provide certain antagonistic ideas to the mentioned ones.
The very first thing the lecture told is that the overall complexity of the brains of the humpback whales might not be associated with their intelligence in navigating the stars for their journey. Giving reasons the lecturer provided examples of birds which usually do have a certain level of highly complex brain system yet they do not have the ability to understand the navigation of such a perplexed night sky orientation. Because of this the lecturer casted doubt on the concept that only having a merely more complex sensory stimuli than the other animals will necessary make the humpback whales more cognitively sound to comprehend the star orientation to serve their purpose.
Second of all, it is said in the reading passage that the humpback whales depend on the night stars as external sign to orient their bodies to remain straight on the track. However, the lecture did not show coherence with the idea as the whales have inbuild magnetic properties which make them vulnerable to the earth's magnetic field. As a result, there is a good chance that the humpback whales get straightened to their tracks by the help of the magnetic field, not by any external forces or objects.
The last contradictions the lecturer in the lecture put forward is that the only doing spy-hopping can not make sure that the humpback whales are following the stars. For his case, he has provided the same case of some sharks which actually do spy-hopping like the humpback whales. However, they do not do navigation purposes rather they do it out of their default characteristics. That is why it can not be eliminated the fact that the humpback whales do the same thing for the same purpose and not for navigation purposes.
