#nematomorpha

(Sources - 1, 2, 3, 4)

Nematomorpha is a phylum of animals that act as parasitoids of arthropods, so named for their superficial similarity to nematodes. They are commonly called Horsehair Worms, Hairsnakes, or Gordian Worms.

Most nematomorph species are 50 to 100 mm (2 to 3.9 in) long, but some can get up to 2 metres (6.7 ft) long! Adult nematomorphs can often be found in water or in damp areas. They have 2 distinct sexes, and the free-living, non-feeding adults can be found coiled into tight balls and knots while mating. They lay their eggs in water, for their larva to be eaten or burrow in through the skin of aquatic larvae and encyst. When the aquatic larvae (the paratenic host) is eaten by their primary host, the cyst hatches and they become a juvenile. The nematomorph lives inside their host, absorbing nutrients, growing, and molting for a few weeks to several months before leaving its host to mate. It often becomes several times longer than the length of its host. Some species cause their host to seek out water and drown itself, thus allowing the nematomorph to exit into its new watery habitat and begin the cycle anew.

Propaganda under the cut:

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 : )

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.

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
