Cryptid Sea Monsters profiles 50 different aquatic cryptid mysteries around the world. Aspiring scientific explorers will discover that many ancient sea monsters turned out to be real creatures—like the oarfish, a real creature that inspired our legends about dragons—and learn about other cryptids that might one day turn out to be real.

Each cryptid has a reality rating of 1 to 6 to show whether it’s more of a hoax or something that has been discovered and recognised by science.

This page-turning guide will inspire curious readers to investigate more on their own, and to understand the relationship between science and myth.
