How does the typical habitat of Yellowfin tuna contrast with that of Bigeye tuna regarding water temperature and depth?
Answer
Yellowfin tends to inhabit shallower and generally warmer waters than Bigeye.
The oceanic environments these tunas frequent contribute to their distinct physiological makeup. Bigeye tuna is characterized by its preference for and habitation in colder waters. In contrast, Yellowfin tuna, despite being migratory across wide oceanic regions, generally occupies waters that are both shallower and warmer compared to where Bigeye is typically found. This environmental difference is subtly linked to the final oil concentration, favoring the colder-dwelling Bigeye for richness.
