arachnoid
Eight-legged creature class
Arachnoid describes something resembling a spider or spider's web, particularly in having fine, tangled fibers or a delicate, weblike structure.
In anatomy, the arachnoid is the middle of three membranes (meninges) that surround the brain and spinal cord, named for its cobwebby appearance.
The term appears in medical contexts such as arachnoid cyst or arachnoid mater.
In botany, arachnoid describes plant surfaces covered with soft, entangled hairs.
