The biggest fish alive in the entire world is a white shark. These creatures, which go by the scientific name Carcharodon carcharias, weigh more than 2.5 tonnes and measure 15 to 20 feet long. They're known for being giant aquatic predators as well. Underwater, a white shark can move reasonably quickly. This ability, coupled with their extraordinary sense of smell, enables them to detect prey from miles away. Carnivorous white sharks typically eat sea lions, seals, mollusks, and seabirds. They may also eat other shark species. They may occasionally consume dead whales as well. Contrary to popular belief, sharks do not intentionally target and feed on humans. However, if provoked, they might attack them. Overall, almost 30% of the total noted shark attacks get done by great white sharks.
