Tuna

Yellowfin tuna (Thunnus albacares) belongs to the family Scombridae, which includes mackerels and other tunas. It is classified under the order Perciformes and is known for its elongated body, streamlined shape, and distinctive yellow dorsal and anal fins. Yellowfin tuna are highly migratory and are found in tropical and subtropical oceans worldwide. They are a popular species for both commercial and recreational fishing.

Skipjack tuna are primarily diurnal, meaning they are more active during the day. They tend to feed and swim in schools in the daylight hours, utilizing the increased visibility to hunt for prey. However, they can also exhibit some nocturnal behavior, especially in areas where they may be less vulnerable to predators. Overall, their activity patterns are largely influenced by light conditions and the availability of food.
