starfishes
Five-armed marine creatures
Starfishes is the plural of starfish, the marine animal with a central body and radiating arms, typically five.
Both starfish and starfishes serve as plurals, with starfish more common in scientific contexts and starfishes in casual speech: We found several starfishes in the tide pool.
