While the origin is in the Greek 954; 957; 953; 948; 951; (knidé "nettle") and refers to the stinging spines of that plant, the term is extended to insects, arachnids and aquatic animals such as aguavivas.

Although now that I think about it, they are not really chains of fastening 128533; . See -phobia, bulldozer.
