You have been a man of war

Looking like a jellyfish with an inflated bell, the Portuguese man-of-war Physalia Physalis is often mistaken for just that. Both animals have bulbous bells, long tentacles and stinging nematocysts, and both live in tropical and sub-tropical waters. But the Portuguese man-of-war is not a jellyfish at all, but rather a colony of organisms. The technical term is siphonophore: an animal comprised of multiple organisms working together. The Portuguese man-of-war is comprised of four such organisms, so specialized in their tasks that their survival is dependent upon one another. The inflated part of the Portuguese man-of-war is the pneumatophore, a gas-filled bladder.

Jump to navigation. The Portuguese man o' war is a highly venomous open ocean predator that superficially resembles a jellyfish but is actually a siphonophore.

Each man o' war is actually a colony of several small individual organisms that each have a specialized job and are so closely intertwined that they cannot survive alone. In this manner, the larger colony consists of a float that keeps the colony at the sea surface, a series of long tentacles that are covered with stinging cells, a rudimentary digestive system, and a simple reproductive system.

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 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.

Each individual Portuguese man o' war is either a male or a female, and they reproduce sexually via a method known as broadcast spawning. Large groups of individuals come together, where females release their eggs and males release their sperm into the water column, all at the same time. This method increases the likelihood that eggs will be fertilized. The Portuguese man o' war is not valuable, commercially, and is common throughout the tropics.

In some places, it is increasing in numbers, likely a result of changing open ocean food webs. When there are large numbers of individuals in an area, it is best to avoid swimming.

In Rich Man's War historian David Williams focuses on the Civil War experience of people in the Chattahoochee River Valley of Georgia and Alabama to illustrate how the exploitation of enslaved blacks and poor whites by a planter oligarchy generated overwhelming class conflict across the South, eventually leading to Confederate defeat. This conflict was so clearly highlighted by the perception that the Civil War was "a rich man's war and a poor man's fight" that growing numbers of oppressed whites and blacks openly rebelled against Confederate authority, undermining the fight for independence. After the war, however, the upper classes encouraged enmity between freedpeople and poor whites to prevent a class revolution.

This week, four more of the stinging critters came ashore along the same stretch of beach and other specimens were reported elsewhere on the island. But don't panic yet.
