The poem begins with a discovery. A remotely operated vehicle, three thousand feet down, finds a siphonophore, and the scientists watching the monitor are stunned into silence. The speaker shares their awe. The creature is described in extravagant images: a carnival float, a thing with "wings" for no air we know, a body of clear tissue where the digestive system glows "lurid as a sunrise." What fascinates the speaker most is that it has no single self. It is a colony whose parts work like organs in one body.
The poem then asks what such a being might tell us. Is life matter talking to itself? Is cooperation a kind of genius? These questions feel sincere and a little dreamy. Then the ending turns sharply. "All are predators," and their beautiful glowing tentacles are lures for prey with "central nervous systems," meaning creatures like us. The mood moves from hushed wonder to a cool, slightly wry chill, as if beauty and danger are the same thing here.
