Therefore, authorities warn people not to touch hammerhead worms with their bare hands and absolutely not to destroy them by cutting them in half. Photo: Canva.

This is because hammerhead worms reproduce primarily by fragmentation. Any part that breaks off will form a new one within 10 days. So, if you cut it in half, it will then turn into two hammerhead worms. Photo: conservationhamilton.ca.

To kill hammerhead worms, experts recommend placing them in a bag and freezing them for 48 hours or soaking them in a mixture of salt and vinegar. Photo: Pong Wira / Shutterstock.
