Portuguese man o' war
The Inner Beauty Of The Beast | Bored Panda. The Man O’ War has tentacles that can reach lengths of over 30 feet long underwater. These tentacles can still deliver a painful sting weeks after having been washed ashore. The Man O’ War is propelled by it’s “sail” and drifts along with the winds and the tides. Whenever I see a Man O’ War washed ashore I often wonder at the places it has been.
This is a closeup of the tentacles of a Portuguese man o’ war. Unlike jellyfish, the man o' war is not a single organism, but a colony of four different kinds of smaller animals, called polyps and medusae, that have highly specialised body types to allow for very different functions, such as digesting and reproducing.
