Great white shark

The great white shark is one of the deadliest sharks in the world and sharks lived before the dinosaurs. It's the largest predatory fish and it grows to be more than 20 feet long and 7,000 pounds. The largest fish in the world is the whale shark and the largest fish ever is the megalodon and the megalodon grew to be 50 feet long and it was probably the apex predator of all time and it went extinct under 2 million years ago. The great white shark has no natural predators other than the killer whale or orca. Great white sharks mainly feed on fish and seals and it's listed as endangered. It is my mom's favorite animal and her favorite terrestrial animal is the hippo and she is an oceanographer but she is also a historian and my brother Elias is a historian too. There is a movie called JAWS about a killer great white.

Caribbean monk seal

The Caribbean monk seal (Neomonachus Tropicalis), also known as the West Indian seal, or sea wolf, was a seal native to the Caribbean sea and now believed to be extinct in 1952. It was hunted for its oil and it was first discovered at the end of the 15th century and its main predators were sharks and humans. This picture of a Caribbean monk seal was taken in the New York aquarium, California in 1910. Other monk seal species include the endangered Hawaiian monk seal and Mediterranean monk seal. The Caribbean monk seal was first described in 1850 by British zoologist John Edward Gray. Some believe that it survived until 1967. The last specimens of Texas were killed between 1926 and 1932. They were found in warm temperate, subtropical, and tropical waters of the Caribbean sea, Gulf of Mexico, and West Atlantic Ocean.
