The article discusses the possibility of using stars for navigation in humpback whales and supports this theory by three reasons. The professor, however, indicates that while this theory may seem fascinating, the explanations in the article aren't convincing, and refutes each of the author's reasons.
First, the article suggests that humpback whales are intelligent animals and could use stars for navigation. The professor states that the intelligence of humpback whales isn't relative to using stars for navigation. He explains that some birds are using star navigation whereas they are not intelligent; like ducks that have average intelligence. He concludes that star navigation is related to animals instincts not to their cleverness.
Second, the author claims that humpback whales migrate in straight directions whereas other animals. The professor rejects this point and says that humpback whales are likely reacting to an external object or force like the Erth's magnetic field. He explains that they are bio-magnetite sensitive towards the Erth's magnetic field; Therefore, they orient themselves accordingly.
Finally, the article states that humpback whales have an odd behavior named spy-hopping that is very rare in animals when they flip and face upward towards the sky. The professor contradicts this point as well and states that sharks also have this peculiar behavior but they don't migrate and they don't star gazing. He explains further that humpback whales do spy-hopping during the daytime when there are no stars to see. Thus it isn't a convincing conclusion.
