The researchers spotted Ramisyllis kingghidorahi off the coast of Japan’s Sado Island in 2019. It’s the third known species of branching worm that reminded the scientists of one of Japan’s most famous kaiju (fictional giant monsters).

Introduced in the 1964 film Ghidorah, King Ghidorah is considered Godzilla’s greatest nemesis. Ramisyllis kingghidorahi isn’t as intimidating, but it does share one incredible ability with its namesake.
Like other branching worms, Ramisyllis kingghidorahi has a single head attached to a body that splits off in an asymmetrical tangle of branches.
Ramisyllis kingghidorahi shares a common ancestor with a branching worm found in Australia, so for now, scientists are studying these two species to learn more.
