The Portuguese man o' war looks like a jellyfish, but it is actually a colony of many tiny linked animals that work together as one. It drifts on the surface of the Atlantic, Indian and Pacific oceans, and its long tentacles sting prey. Its sting is painful to people, and in some cases it can kill them.1

Cara mengenalinya

A gas-filled bladder called the pneumatophore floats on the surface and acts as a sail.1
Long tentacles, which can reach over 30 m, hang below the surface.1
The float can be up to 30 cm long, 13 cm wide and 15 cm tall.1
Groups can be large, sometimes over 1,000 animals.1
The sail may be left- or right-handed, depending on the way the wind catches it.1

Sering dikelirukan dengan: It superficially resembles a jellyfish, but it is a siphonophore, a colonial animal made of many smaller units called zooids.1
