Welcome back Herders! The Portuguese man o’ war is a predatory species. It uses its feeding tentacles to sting and paralyze small fishes, pelagic crustaceans, and other invertebrates. The feeding tentacles may be up to 160 feet (50 m) long in some individuals! These tentacles deliver a powerful sting and are also used for defense against predation. Few species eat the Portuguese man o’ war, but some predators that specialize on stinging, gelatinous invertebrates (e.g., loggerhead sea turtles and ocean sunfish) are known to feed on this and other siphonophores.
