AGE: 445 million years 

Place: ocean water, muddy bottoms

How Long Have Alligators Been on Earth?
  • A. 245 Million Years
  • B. 240 Million Years
  • C. 220 Million Years
  • D. 200 Million Years

The horseshoe crab is the perfect example for the title “survivor”. In 2008, a team of Canadian researchers found that it has been on earth for at least 445 million years. Horseshoe crabs live on the Atlantic coast of North America and around the Florida coast. Humans are the biggest threat to horse crabs, and they are used for biomedical purposes.

Crocodiles

AGE: 200 million years 

Place: lakes, rivers, and wetland

Crocodiles are the ultimate survivors. They shared the world with dinosaurs. It is even said the Cretaceous period (145-66 million years ago) was full of giant crocodiles like Sarosuchus, Dryosaurus, Deinosuchus, Shieldcroc. 

Sponges

Sponges

AGE: 600 million years

Place: Marine water 

Sponges lack cells, tissues, and organs and have asymmetrical bodies, yet they are among the greatest survivors of evolution. There are nearly 10,000 different species of sponges. Researchers found that the fossil records of sponges date back to 580 million years ago. 

Velvet Worm

Velvet Worm

AGE: 540 million years 

Place: Rainforests  

Fossil analysis says Velvet worms are 540-million-year-old, and they are closely related to crabs and spiders. Velvet worms can be found in moist and dark places around the tropics of Australia and New Zealand. Velvet worms are about 8 inches long. 

Duck-Billed Platypus
