The material discusses if humpback use stars to navigate their immigration trips. While the reading looks at the topic from one perspective, the listening challenges all the points outlined in the reading passage and mentions that the theory of humpback whales use stars to navigate over the open seas is fascinating, but the evidence that the reading states are not convincing.
First, the author points out that humpback whales are very intelligent, so they have the ability to use stars to navigate. On the other hand, the professor opposes this and posits that there is no connection between intelligence and using stars for navigation. The lecturer adds that some animals, such as birds are not highly intelligent, but they use stars to navigate. According to the lecture, this ability is a natural instinct in these animals and not connected to the degree of intelligence.
Second, the writer contends that humpback whales immigrate in straight lines and this is evidence that they use stars to find out their way. However, the lecturer refutes this and cits that there is a different explanation of migrating humpback whales in straight lines. The professor explains that they use external objects or force, and this force could be the electric magnetic field. The speaker brings up that humpback whales have biomagnetide in their brains that makes them sensitive to the electric magnetic field, so they are more likely to use it to travel in straight lines.
Third, the reading states that humpback whales perform spy-hopping behaviors, they could use this attitude to look at the stars. Conversely, the professor contradicts this and cits that spy-hopping does not mean that whales use stars to navigate. The lecturer says that other animals do spy-hopping, such as sharks, and sharks do not migrate, but they could use this behavior to hunt their prey. Furthermore, the speaker adds that humpback whales do spy-hopping during the day when there are no stars.
