#geonemertes

the worm fires its sticky proboscis like a harpoon, presumably injecting venom at some point.

this is Geonemertes pelaensis, one of a scant few terrestrial examples of a mostly marine phylum (Nemertea). it’s an invasive species in the US and elsewhere, implicated in lowering counts of some soil arthropods.

it also has a very cute face.

Genus Geonemertes

...a genus of terrestrial nemertean (ribbon) worms that are distributed throughout Indonesia, some Indo-Pacific islands, and parts of Australia. Members of Geonemertes are often found in the leaf litter and on plants and reportedly have a diet that includes insects and other arthropods. Like their marine relatives, members of Geonemertes feed by shooting out their proboscis which can stretch to almost their entire body length. Like most terrestrial ribbon worms this group is poorly researched and much is still unknown about their biology and ecology.
