What color covers the dorsal side of the Yellowfin Tuna to camouflage it against deep water when viewed from above?
Answer
Dark blue or dark metallic blue
The coloration strategy employed by the Yellowfin Tuna involves countershading, a classic marine camouflage technique. The upper half of the fish, known as the dorsal side or back, possesses a deep, rich pigmentation, described as dark blue, dark metallic blue, or almost black. This dark coloration effectively blends the fish into the darker backdrop of the deep water when the predator or observer views the tuna from above.
