go to the water, o locust! your thirst is unquenchable, and i am so alone coiled in your abdomen. sit and drink by the muddy ephemeral pond and you will hardly notice when i slip out : )
anyway why was this guy under a log. brother you need to be wet (unidentified horsehair worm, phylum nematomorpha)
Mollusca: Snails, slugs, cephalopods, bivalves, chitons, limpets, and others. This group contains the largest invertebrates, the giant and colossal squids. They are the largest marine phylum, but many members are terrestrial. Although they are incredibly diverse in body shape, all Molluscs generally have a hard "radula" used for eating, a mantle that may secrete a hard shell, and a body mostly composed of dense muscle. These animals can be predators, herbivores, filter feeders, symbiotic, and even parasitic. This phylum exhibits remarkable diversity overall.
Nematomorpha: Horsehair Worms. Until adulthood, all Horsehair Worms are parasites of various insect species. They are mostly freshwater, with a few saltwater species. As the larvae grow into adulthood, many can alter the behavior of their insect hosts by compelling them to fall into bodies of freshwater. When it senses water, the adult worm emerges to spawn. These parasites are important in controlling insect populations, and in some cases, providing a food source for fish. Without them, the effects would cascade down the food chain and lead to shifts in the ecosystem's balance.
Loricifera. This phylum is made up of microscopic animals that attach themselves to gravel. It is one of the most recently discovered groups, first described in the 1980s
Nematomorpha. This phylum is known as horse-hair worms. The adults are free-living, but larvae are parasites of arthropods
The cousins of roundworms! Much longer and thinner, often macroscopic in size, they get a bad reputation for their parasitic lifestyle. You might have seen videos of huge worms crawling out of an insect - yep, that was them.
But nematomorphs, or horsehair worms, aren't anything evil - no phylum is, really. In fact, the dramatic worm emerging from an insect is only the larva, with the adult living a casual free-living worm life, swimming in the seas or climbing in the trees!
They are also called Gordian worms - referring to the Gordian knot, as they have the habit of coiling themselves in intricate knots. In fact, they are often found like this after emerging from their host, usually several times smaller than themselves. (Details of the parasitic cycle and picture below)
As larvae, horsehair worms will take full control of their host - often a cricket, pushing them to dive into the water where the adult will emerge and lay its eggs. As gruesome as the process can look, the host might survive. Or, on the flip side, get eaten by a predator, in which case the horsehair worm can still wiggle out of the latter's digestive system, perpetuating the cycle.
A BRACKET WHERE THE 37 KNOWN PHYLA OF ANIMALS (extant and otherwise) WILL BATTLE TO THE DEATH. ONLY ONE MAY BE CROWNED CHAMPION-- AND ASCEND TO THE STATUS OF KINGDOM (i have this power)
WHO WILL IT BE? THE CHORDATES, CONTAINING EVERY KNOWN VERTEBRATE INCLUDING YOU AND ME? I FEEL LIKE THAT'S A BIAS. MAYBE THE HUMBLE TARDIGRADES, THE INTERNET'S FAVOURITE EXTREMOPHILES? OR WILL IT BE THE PENIS WORMS? I FEEL LIKE IT'S GONNA BE THE PENIS WORMS.

round three wait and see!!!
this bracket doesn't require nominations, as the candidates are already set out all nicey for us by Science. how cool of them. Now we make them beat each other senseless for our sick amusement :)
HOWEVER please send asks, suggest representative species or images to make sure we see them at their best, send propaganda/fun facts youd like the filthy electorate to know before they condemn your fav to the deepest most basal pits of taxonomic superhell. lets all get to know the Beasts together. Before we make them fight to the death.
This was one of my final projects from last quarter, a story about Nematomorphs.
The phylum Nematomorpha (also called horsehair worms or Gordian worms) are small freshwater worms found all over the world. They live as parasites growing inside of larger arthropods such as grasshoppers, crickets, and mantises. When the worm reaches adulthood, it is able to alter the behavior of its host, compelling it to jump into water. There, the horsehair worm emerges from its host and lives the rest of its life as a free-swimming adult. Remarkably, the insect hosts are capable of surviving this process—if they don’t drown or get eaten by a hungry fish.

As the larvae grow into adulthood, many can alter the behavior of their insect hosts by compelling them to fall into bodies of freshwater. When it senses water, the adult worm emerges to spawn. These parasites are important in controlling insect populations, and in some cases, providing a food source for fish. Without them, the effects would cascade down the food chain and lead to shifts in the ecosystem's balance.
Orthonectida: Simple, yet poorly-understood wormlike parasites surrounded by hair-like cilia. Their hosts are generally invertebrates, both freshwater and saltwater. Unlike many other parasites, adult Orthonectids will leave the host when ready to reproduce, and will spawn in the open, independent of the host. The resulting larvae are covered in cilia to help them swim to find a new host. Once a new host is found, the larva will separate asexually into the next generation of Orthonectids.
We found these in our garden during a rainy morning in late spring. They were scattered under a plum tree but we collected them into a pile to get photos and video. Not sure what species these are but they most resemble nematodes in the Mermithidae family. They resemble horsehair worms (Nematomorpha) but there are no bodies of water nearby. They may be a species in the Mermis genus and like horsehair worm, they are parasites of insects. Their behavior resembles Mermis nigrescens but there are few grasshoppers (their common hosts) but we do have a lot of tree crickets in our garden. They probably had come to the soil surface to mate. Their scanning behavior is likely them sensing light to determine their direction. By noon , these worms had disappeared from the surface.
