Hammerhead worm

Bipalium adventitium

Description:

A voracious predator of earthworms, this species is distinguished by the single maroon line running down its yellow body. It crawled slowly and left a track of shiny, mucoid secretions on the plank.

Habitat:

I found it underneath a decomposing wood plank that housed a termite and carpenter ant colony.

Notes:

Bipalium is an invasive species in the US. Although found on land, this hammerhead worm produces tetrodotoxin to paralyze its prey, the same compound in pufferfish and a few other fish.

I did and I just posted it. It's a different species, but the second reference shows the head and stripes that identify both mine and yours. Thanks for the help Mauna..

I had no idea what a "Hammerhead Worm" was til this spotting. Then shortly after seeing it, I found one at my daughter's place. I'd never have noticed it without this spotting. Thanks.
