The Tiger Shark
Tiger sharks are considered to be one of the most dangerous predators in the ocean, so it was reasonable for Hauser to be even more frightened at this point of the dive than before.
Tiger sharks can grow to be as big as 35 feet long, weigh around a ton, and are known for attacking humans. They are found in warmer areas of the Pacific Ocean, and will not stop their attack until they get what they want.
