The Answer

PacSci-Doku: "Mondo Predator" Answer

The question in this edition is:

What is gobbling up the common earthworm?

The answer: Giant Worm

Native to Asia, the “giant” foot-long “Hammerhead” flatworm does not belong in Europe. It eats its prey by excreting tetrodotoxin, which paralyzes its prey. Hammerhead flatworms are now found in Europe, but the assumption is they will spread elsewhere as global trade brings many types of accidental visitors from elsewhere in the world. It is still not clear what this Asian invader will do to the local ecosystem, which depends on the earthworms for help in developing a healthy soil ecosystem. Check out what the Hammerhead flatworm looks like and read more about this invasive species.
