Marlins are partial to tuna, even though tuna are themselves top of the line predators. The blue marlin is an extremely fast and voracious hunter that uses its spear-like bill to injure and stun its prey.

The wahoo, which is a member of the Scombridae family, the same family as tuna, is fast and powerful enough to overcome a large tuna. Wahoo can weigh over 150 pounds and reach speeds of 60 miles per hour.

False killer whales are not true killer whales, but they get their name from similarities in the shape of their skulls and teeth to real whales. These large dolphins can be over 19.5 feet long and are found in tropical waters all over the world. False killer whales experience success when hunting large and quick fish, such as tuna, because they hunt in groups. In fact, experts have observed false killer whales passing prey back and forth between them before beginning to eat.
