sea anemone
B2neutral, technical (marine biology)
Definition
Meaning
A marine animal that looks like a flower, with a soft, tubular body and a ring of tentacles around its mouth, often brightly colored and living attached to rocks or coral.
Can metaphorically refer to something delicate, beautiful, but potentially stinging or dangerous; or to describe a passive, anchored entity that waits for sustenance to come to it.
Linguistics
Semantic Notes
Despite its flower-like appearance, it is a predatory animal (cnidarian). The name combines 'sea' (habitat) with 'anemone' (flower name, due to visual resemblance).

Learning
Memory Aids
Mnemonic
Think: A SEA flower named after the land flower ANEMONE. 'An enemy' in the sea? No, it's an 'anemone' – a beautiful but stinging animal.
Conceptual Metaphor
BEAUTY IS DECEPTIVE / PASSIVITY IS WAITING (like a flower, but it's a patient predator).

FAQ
Frequently Asked Questions
It is an animal, specifically a predatory marine invertebrate related to jellyfish and coral.
Most are sessile (fixed in place) as adults, but they can glide very slowly on their base or detach and float if disturbed.
Most have stings too weak to affect human skin significantly, but some tropical species can deliver painful, venomous stings.
It's a mutualistic symbiosis. The clownfish is protected from predators by the anemone's stinging tentacles, and in return, it defends the anemone from certain predators and provides nutrients through its waste.
