okie dokie, about the blue bottle
It is also known as the Portuguese man-of-war
Classification
Phylum Cnidaria (sessile polyp 'like hydrant', swimming medusa)
Class Hydrozoa (medusae small, solitary or colonial)
Order Siphonophora (free swimming)
Genus
Physalia
The blue like 'head'(pneumatophore) is the drifting mechanism and is filled with carbon monoxide. There are 3 different types of zooids (tentacles). When looking at the blue bottle (not that many of us do) the zooids closest to the drifting mechanism are the gastrozooids, or the feeding polyps. the next zooids are the gonophores , are for reproduction; and then the long zooids that one usually sees (basically the only ones you see if you dont know how to differentiate them) are the dactylozooids, which are the feeding tentacles. These dactylozooids sting the prey and then lift it to the lips of the gastrozooids.
The Portuguese man-of-war is a colony with a rainbow-hued float of blues and pinks. The zooids are laden with nematocysts and capable of inflicting painful stings (as im sure many have experienced). The pneumatophore acts as a type of nurse-carrier for future generations of individuals that bud from it and hang suspended in the water.
So... in other words each individual that one sees on the beach or in the water does infact consist of a colony and it may have as many as 1000 zooids
