I have read that, too, about earthworms. Robins eat them as do many other creatures, they are affected by the poisons people put on their lawns and they die in the rain on sidewalks and roads...yet, still they thrive. It will be interesting to see if the hammerhead worm can help balance the worm population a bit.
I guess the cannibalistic nature is also good in this species. I will definitely keep an eye out for them, and see how their populations fluctuate. It may be seasonal, when the there is a lot more moisture and prey. Now I see less coquis maybe their mating season is over ?
I know these as ribbon worms. Not sure what they eat but you generally find them under rocks or damp places around rhe garden. The worst thing about them is the stinky slime they secrete... doesn't wash off very easily.
yep - I have seen them too in my area. Good description. Unfortunately that means that they can withstand cold weather. Hmmm....on the other hand maybe they hitchhiked on the annual plants I plant every year. I have seen a couple about 3-4 inches long.
