On tiny Kudaka Island, off the coast of Okinawa, Japan, Yoko and Setsuko are master sea snake catchers. At 70 years old, they’ve been hunting poisonous sea snakes at night for over 40 years. As explained in this Wild Japan clip from BBC Earth, “It’s a skill that’s been passed down the generations here for at least five centuries.”
The snakes are Black-banded sea krait, known as irabu in Japanese. Though the snakes’ venom can be 10 times more powerful than rattlesnake venom, the locals serve irabu smoked and as a soup.
