Nomeus gronovii, the man-of-war fish or bluebottle fish, is a species of fish in the family Nomeidae, the driftfish. It is a distinct species characterized by an elongated body, large eyes, and blackish-blue stripes, growing up to 39 cm long. Inhabiting warm, deep pelagic zones of the Atlantic, Pacific, and Indian Oceans between 200 and 1,000 meters deep, this fish lives within the tentacles of the Portuguese man o' war, feeding on its tentacles and gonads. Although it possesses resistance to the toxin produced by the man o' war, this species actively avoids larger tentacles and occasionally feeds on smaller ones. The species' agility, high vertebrae count, and specialized skin features contribute to its toxin avoidance. It is the sole known species in its genus and undergoes a lifestyle shift from pelagic to demersal as it matures. Reproduction involves egg release by females, yielding larvae adapted to open water life, with each female capable of producing 100 to 1000 offspring.
