PYROSOMES
Spawn of the eastern Pacific transformed
By a blob of water bizarrely warmed,
Something like ghostly Tibetan longhorns:
All over the ocean are pyrosomes.
When fishermen were trolling for chinook
Says Alaska Fish and Gamesman Shaul,
They came up with them on every hook.
Ten thousand appeared on a research trawl.
We don’t even know what they consume.
We only know their luminscent firebody bloom.
