Which environmental condition do Bigeye tuna generally prefer swimming in, contrasting with Yellowfin?
Answer
Colder waters.
The preferred habitat temperature influences the physiological differences between the two species. Bigeye tuna exhibits a preference for, and swims in, colder oceanic waters. This contrasts with Yellowfin tuna, which generally tends to inhabit shallower and comparatively warmer waters. It is suggested that Bigeye's habitation in colder environments might lead to a slower metabolic rate, facilitating the greater accumulation of the desirable fats that ultimately define its superior quality for rich flavor profiles.
