This material addresses the question of whether or not the humpback whales are migrating relying on stars or not. The reading passage suggests that they do, because of their intelligence, abstract behavior and the lines of their migration. The listening passage, on the other hand, refutes this information by stating that none of this can be an evident of the humpback whales orientating by stars.

To begin with, the reading passage highlights that due to the structure of the brain of the animal, it can be stated that it is highly inteligent. Consequently, the humpback whales could use the night sky in order to navigate. Meanwhile, the professor casts doubt on this and argues that there is not a connection between an intelligence and navigation; for instance, ducks have an average intelligence, yet they are able to utilize stars for their migration. She explains that the reason is their instinct.

Additionally, the article posits that the humpback whales follow straight lines during migration, which is a clear indicator of their skills to orientate with sky. However, the professor advocates a different approach by providing the following details. Namely, she mentions that the magnetic field seems to be a better explanation of the straight lines. These animals have biomegritate, so they are sensitive to the magnetic fields.

Finally, the author invites attention to the fact that humpback whales have a really bewildering behavior. From time to time they stop and look upwards, like they try to observe the sky. The rare function they do, is known as spy-hopping. This goes counter to the information in the listening passage, according to which the spy-hopping is also used by sharks, but they use it only for hunting, they do not migrate; thus, the humpback whales do that also during the day, obviously, the daylight is an obstacle to observe the sky, so, as she sad it is a pure speculation.
