Hagfish and Their Defense Mechanisms

The video explores the defensive mechanisms of hagfish, which produce slime to deter predators like sharks. Researchers from the Museum of New Zealand conducted a study using remote cameras to observe these interactions. Despite multiple attempts by predators, the hagfish's slime defense proved effective, highlighting their evolutionary success over 300 million years. The findings were published in a scientific journal.
