Experts have warned Brits to keep an eye out for two new species of killer flatworms that could pose a risk to some native earthworm species as well as the soil ecosystem.
These hammerhead worms only measure about 3cm long. But despite their tiny size, it's thought they could be a danger to British species that gardeners and farmers rely on.
Flatworms can kill common garden insects including snails and earthworms, as scientists warn they could become an invasive species, reports Glasgow Live.
