Future of the Bluefin tuna

The bluefin tuna is a fish that lives in oceans that are not in a tropical rainforest. There are about 500-100 meters under the ocean in the pacific and atlantic. They live in water temperatures between 60-70°F. They need highly oxygenated water like open spaces and high energy water. They are huge fish, some are even 500 pounds which is crazy. Some even live in the mediterranean sea. They are mostly like 70-85 pounds. The biggest bluefin tuna was 180 inches and over 1500 pounds. When the bluefin tuna fish species evolves, it will be way smaller and weigh so much less. They will change habitat like they will change parts of the oceans. They will change so much in the future.
