Diet and Feeding Habits
Carnivore (meat-eater)
Small fish, fish larvae, and plankton
Uses long venomous tentacles to sting and paralyse prey.
Both predator and prey in the marine ecosystem.
The tentacles contain special cells called nematocysts. When touched, they release venom that stuns prey instantly. The captured food is then passed to feeding zooids for digestion.
Behaviour and Lifestyle

- Lives in groups called fleets.
- Can deliver a painful sting to humans.
- Sting remains active even if the animal is dead.
Even though it looks delicate, the Portuguese Man Of War is a powerful predator. It spends its entire life drifting on the ocean surface.
