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,

Both the lecture and the passage are regarding whether stars navigate humpback whale for migrating long distance or not. Albeit author strongly accentuates that stars are plausible reason how whales travel long distance, lecturer opposes this claim by presenting several counterarguments.
Firstly, author links the intelligence of humpback whales with utilizing stars as a navigator, and author deems that since humpback whales are exceedingly smart animals, they can use stars for traveling. However, lecturer refutes this statement by demonstrating other animals for upholding his counterargument. Furthermore, lecturer asserts that birds use stars so as to travel long distance, but they possess average cognitive ability, and lecturer considers that it is due to instinct rather than intelligence.
Secondly, author emphasizes that humpback whales migrate in straight lines, and they can only maintain traveling in the straight line by using external objects for orientation., and thus, stars perhaps are the external object that helps them to travel. That being said, lecturer rebuts this claim by mentioning that humpback whales also can use an external force for moving in straight lines. Consequently, they can utilize magnetic fields, since they have bio magnetite in their brain.
Thirdly, author states their bizarre behavior: sometimes they take their head out of water, and look upwards. To this end, author presumes that they are conducting this behavior in order to observe stars. On the other hand, lecturer contradicts this belief by illustrating sharks, which tend to do this behavior, called spy-hopping so as to hunt theirs preys. Therefore, lecturer mentions that it may be the same for humpback whales, and besides they are doing spy-hopping in the day, when it is not feasible to notice stars.
