In the reading passage, the author provides three possible theories that show humpback whales may navigate by the stars. These arguments, however, are challenged by the lecturer.
The first theory is that humpback whales are capable of migrating by the stars because they have complex brains. Superior than other creatures, whales develop well cognitive ability to assist themselves orient. The lecturer rebuts this view, suggesting that some birds, such as ducks, also use stars to navigate; nevertheless, ducks seem don’t have high intelligence. Thus, there is no direct connection between intelligence and abilities of navigating by stars.
The second theory indicates that stars are the indispensable objects for whales to maintain straight direction over the boundless ocean. Unlike terrestrial animals, whales don’t have stable forces to locate, they can solely depend on the stars. The lecturer argues this point, providing another possibility. Instead of utilizing the stars, whales use their biomagnetite to sense the Earth magnetic field.
As for the final argument, a behavior called spy-hopping, exhibits that whales could float out of water so as to look the stars. However, the lecturer refutes this again, citing sharks as an example. The lecturer asserts that sharks do spy-hopping as well but only for hunting rather than migrating or looking stars. Moreover, whales are observed migrating and spy-hopping during days, which make this assumption implausible since there is no star in the sky.
