It is 930 miles wide and oval-shaped. The surface area of the Gulf of Mexico is 600,000 square miles, while the average depth is 5,299. The deepest point in the Gulf of Mexico is the Sigsbee Deep, which is between 12,303 and 14,383 feet deep.

The Biggest Fish Found in the Gulf of Mexico

Surprisingly, the largest fish in the Gulf of Mexico, isn’t just a fish, but a shark as well. Whale sharks are the largest fish found in the Gulf of Mexico. Whale sharks are most common in northern parts of the Gulf of Mexico. They are docile sharks, and despite being named whale sharks, are not related to whales. These elegant fish live in deep water and are hard to spot. It’s not ever guaranteed you will swim or see a whale shark up close, but you have the best chance of spotting them in Mexico, Belize, Australia, and Tanzania.

About Whale Sharks

Whale sharks are beautiful, slow-moving fish. They are massive and found almost everywhere in the world. Their conservation status is threatened. They were first caught and recorded in April 1828 when a whale shark was harpooned in Table Bay, South Africa. A year later, Andrew Smith described the whale shark in detail. These large fish have long lives. Scientists estimate that most whale sharks live between 80 to 130 years.

Size and Appearance

Whale sharks are massive and unique. They are easy to spot and distinguish from other sharks because of their large open mouths and flat bodies. They swim slowly and gracefully and have white spots and stripes on the top of their bodies. Their bellies are white and they have thick and rough skin, despite looking smooth. Whale sharks grow up to 61 feet long. However, most whale sharks reach 48 feet long. Their mouths are also very wide. For instance, a 39.7-foot whale shark has a mouth size of 5.1 feet. This is the height of some fully grown adult humans!

Diet

These large sharks aren’t picky eaters. They also don’t hunt for food like other predatory sharks, instead, they are filter feeders. There are only three filter-feeder shark species including the basking shark and the megamouth shark. Whale sharks mainly eat plankton, fish, squid, and eggs. They eat by opening their mouths wide and swimming slowly. Sometimes, they suck in deeply, which pulls prey right into their mouths. While whale sharks aren’t aggressive, they are smart. They have been recorded waiting for the right time, before feeding on mass spawning of fish shoals. To keep up with their size, whale sharks eat a lot. A young juvenile whale shark eats about 46 pounds of plankton each day.

Predators

Whale sharks don’t have to worry about most predators. Because of their size, they aren’t targets of whales, sharks, or other large sea animals. Instead, only young juvenile whale sharks are hunted by blue marlins, great white sharks, and blue sharks, but it’s rare. The biggest threat to whale sharks is humans. Whale shark meat and liver oil are highly sought after in some countries, which has led to their threatened conservation status.

The Largest Whale Shark Ever Recorded

The largest whale shark ever recorded was an impressive 61.7 feet. These large sharks easily weigh up to 21.2 tons. Although this is the largest record so far, it doesn’t mean it’s the maximum size a whale shark can grow up to. There is still a lot that we, and scientists don’t know about this majestic and massive shark.
