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, much as early human sailors did. What we know about humpback whales makes this a distinct possibility.
First, humpback whales seem to be intelligent enough to use stars to navigate by. Whales' brains have a high degree of complexity—a common determiner of intelligence. This suggests that the whales' brain power far exceeds that of most other animals. The whales' well-developed cognitive ability seems to provide a sound basis for the ability to use a complex, abstract system of sensory stimuli such as the night sky for orientation.
Second, humpback whales migrate in straight lines. Animals can maintain movement in a straight direction for long distances only if they orient themselves by some external objects or forces. Many birds and other terrestrial creatures, for example, use physical landmarks to help them stay on track as they migrate. Whales, which swim in the open ocean, cannot rely on land features; they could, however, rely on stars at night to provide them with external signs by which to maintain direction over long distances.
Third, humpback whales exhibit an unusual behavior: they are sometimes observed floating straight up for minutes at a time, their heads above the water as though they were looking upward. The behavior is known as spy-hopping, and it is very rare among marine animals. One explanation for the function of spy-hopping is that the whales are looking at the stars, which are providing them with information to navigate by.
The reading and lecture are about whether humpback navigate in accordance with celestial force. In the reading, three probable explanations which support that the species utilize stars to find their way. The lecturer is the opinion of these explanations are faulty.
First, the author posits that the humpback whales has satisfactory brain, which means that this creature is smart and possess appreciable cognitive ability to employ celestial bodies for navigating. This specific interpretations are challenged by the lecturer. He claims that other animals such as ducks use this navigating to migrate. However, their cognitive aptitude is comparatively smaller than the whales, and even less than average, which suggests that the intelligence and finding its path to migrate is not associated with each other. Therefore, the well-developed brain of the whales do not provide possibility of migrating since migrating is inborn instinct of animals.
Secondly, in the reading, it is claimed that this animal travels through straight lines, and this travelling process requires external powers or matters, one of which can be stars. Thereby, this animal probably orients its way thanks to stars. Nonetheless, the lecturer refutes this idea by mentioning that one of external forces can be magnetic field which is widely utilized by other animals migrating to far-flung area. Moreover, the magnetite, which is substance playing the role of orientation of magnetic, was found from the brain of the whales. Hence, this animal might employ the magnetic field rather than bodies in the heavens.
Finally, the author suggests that humpback showcase the spy-hopping, movement of floating near to the surface of water, which is explained with the idea that it see the stars and use this information to navigate. The lecturer, however, mentions that other creatures such as sharks make this particular movement. Furthermore, sharks do not relocate to the distant place, and this movements is done during a daytime, when the stars are invisible. Thus, spy-hopping does not play the role of looking at stars.
