the.com/sea anemone

means A soft-bodied marine animal that anchors itself to rock and uses a ring of stinging tentacles to stun and grab passing prey, then stuffs it into the single opening that serves as both mouth and anus.

from Named for its resemblance to the anemone flower — the word 'anemone' itself traces to Greek 'anemos,' meaning wind, via a plant whose blooms were fancied to open only when the wind blew (the popular tale ties it to Adonis's blood sprouting windflowers, but that's myth, not word-history). Naturalists borrowed the flower's name wholesale for the creature once they saw its crown of waving, petal-like tentacles — a case of nature's imitation fooling the taxonomists first.
