While more delicate species rake in bits of food, this anemone has sturdy tentacles that bring down big game like shrimps and small fishes. Like other anemones, they grow larger when food's plentiful and "grow" smaller when food is scarce.

Small fish called painted greenlings sometimes lie in fish-eating anemones, much like clownfish do in tropical anemones.
