arachnid

That includes the millions of species of insects, arachnids, and nematode worms that make up a major animal group called the Ecdysozoa.

For Waterhouse, the discovery of the arachnid wasn’t just throwaway internet fodder — it became a metaphor for her own memoir and, in turn, “Memoir of a Sparklemuffin,” due Sept. 13 on Sub Pop.

The early worm gets the arachnid, fossil research by an Oregon State University scientist has shown.

Whatever its evolutionary affinities, these spiny arachnids appear to come from a time when arachnids were experimenting with a range of different body plans.

Ticks are small, eight-legged bloodsucking parasites — arachnids, not insects — that feed on animals and sometimes people.
