Also astonishing to see in the Cut-Off Channel was several of these adult Horsehair Worms (Nematomorpha), related to Nematodes. The larvae are parasitic on arthropods. (Hope am not 1 of the few adults to suffer accidental parasitism by them!). #WormWednesday #Nematomorpha #rivers #invertebrates 2/25

A #WormWednesday #backyard #biodiversity entry: #HorsehairWorms! Nematomorpha -- AKA #Gordian worms for their tendency to tie themselves into knots as free-living adults, the parasitic larvae infect a variety of arthropods, directing the host to drown itself & return the emerging adult to water.

Ah, Nematomorpha. Ziemlich faszinierend, aber ich finda Parasitologie sowieso super interessant.

Is it weird that my first thought was horsehair worm parasites? I thought that was pretty niche but no, go Team Nematomorpha

I've seen 17 of them alive and in-person:
Annelida, Arthropoda, Brachiopoda, Bryozoa, Chordata, Cnidaria, Cycliophora, Echinodermata, Mollusca, Nematoda, Nematomorpha, Onychophora, Platyhelminthes, Porifera, Priapulida, Rotifera, Tardigrada
Of those I have eaten 5 of them in the past.

"Zombifying" hairworms compel their insect hosts to jump into water & drown. But what's REALLY weird about these parasites is they're missing 30% of genes found in all other animals, for growing wee hairs called cilia 🧪https://www.cnn.com/2023/07/18/world/horsehair-worms-parasites-missing-genes-scn
Missing genes in ‘mind-controlling’ worms pose an evolutionary puzzle | CNN
Genetic analysis has revealed that horsehair worms, of the phylum Nematomorpha, took an evolutionary detour that cost them about 30% of genes found in other animals.

Nematomorpha! That’s what I was thinking. The only species that I have observed in US Northeast lacked any bristles and had minimal segmentation.
