Sea snakes are arguably the most poisonous vertebrates in the world. But the marine biologist Dr. Glen Burns treats her so lovingly that you forget the danger. "Maybe in 20 years of working with the snakes I haven't been bitten because I've started to think and feel like a sea snake." But if the marine biologist is wrong and is bitten, he will no longer reach the mainland 100 kilometers away alive. Glen Burns researches the dangerous animals in the wild.

Mysterious sea snakes

Aquarium research is safer, but hardly provides any insight into the natural behavior of sea snakes. There are plenty of puzzles for Glen Burns. Some species migrate thousands of kilometers to mate. Why these snakes have migrated into the water over time, if they still have to breathe regularly, and why sea snakes have such good eyesight when they only use their sense of taste when hunting - these are the questions Glen Burns is investigating along the Great Barrier Reef, the place from which the sea serpents probably began their triumphal march through the tropical seas. The marine biologist worked with 17 species of sea snake and, using transmitters, determined that one species had traveled more than 3,000 kilometers to forage.
