The reading states that Humpback whales travel long in the ocean by the use of starts and provides three reasons to support this claim. However, the professor opposes this argument and refutes each of the points made in the reading.
First, the reading claims that whales are smarter animals than others and this gives them the cognitive ability to use stars as their navigation tool. The professor disagrees with this argument by explaining that there is no connection between intelligence and the use of stars as a migration tool. He mentions that other animals like ducks use stars while they do not have highly intelligent and are among average smart animals. Therefore, they are using stars based on their instinct and we cannot relate this to their smartness.
Second, the reading argues that whales move in a straight line and they do this by stars. It mentions that other animals use external objects to help them move straight and for whales that travel in the water there is no land to help, so, stars are the only option. The professor opposes this idea and believes that whales are sensitive to the Earth's magnetite feature and they are able to move in a straight line by a bio-magnetite characteristic which is defined as the whales' sense of magnetite. He thinks that this sense helps whales to travel in a line and star is not the reason that they can move in a straight line.
Third, the reading claims that there is a rare behavior called spy-hopping that has been observed in whales. In this behavior whales' head stays out of water for few minutes. The reading believes that whales do this to see stars. The professor refutes this idea and argues that this behavior has been observed in other animals like sharks as well. Spy-hopping in sharks is a way for them to look for other animals to hunt them and probably in whales it is not for seeing stars either. He also mentions that these animals do this behavior at day times as well, when there is no star in the sky, so, it cannot be related to seeing stars.
