What animals eat/attack bluefin tuna

Bluefin tuna, being large and powerful fish, have few natural predators, but they can be preyed upon or attacked by several animals, including: 1. **Sharks**: Various species of sharks, such as great white sharks and mako sharks, are known to attack bluefin tuna, especially when they are young or injured. 2. **Orcas (Killer Whales)**: Orcas are known to hunt bluefin tuna, particularly in areas where both species are found. They are highly intelligent and social predators. 3. **Larger Fish**: Other large predatory fish, such as swordfish and larger tunas, may also attack juvenile bluefin tuna. 4. **Humans**: While not a natural predator, humans are significant threats to bluefin tuna populations through overfishing and habitat destruction. These predators typically target younger or weaker individuals, as adult bluefin tuna are formidable due to their size and speed.
