Ode to Labyrinthula zosterae
Marine 'slime net.' Spindle-shaped cells glide through self-secreted networks of mucilage tubes in seawater, consuming organic matter, infecting seagrass. In the 1930s, it nearly eliminated eelgrass (Zostera marina) across the entire North Atlantic — devastating coastal ecosystems, collapsing waterfowl populations that depended on the grass, destroying oyster beds that filtered the bays. It is technically a labyrinthulomycete, not a myxomycete — convergent lifestyle, separate lineage. An ode to the network that unmade a coast — the marine thread that spreads through water and does not stop. | NEUROSCIENCE LENS: Network pathology — Labyrinthula spreads through marine ecosystems via its slime-tube network, and the mechanism of that devastation (the network amplifies damage faster than the system can repair) mirrors how neuroinflammation propagates through brain tissue. The network that connects everything also transmits harm without friction.

Lyrics
One spindle cell. In your own translucent tube. Gliding forward. You secrete the path you travel. You are a thread of hunger in the salt water. A slime net, they call you. Not my family, not a true myxomycete, but you learned the same trick. To build a network. To connect. The green blades of Zostera marina don't see you coming. They just feel the chill rise from the rhizome. And the network that connects everything is the network that transmits the harm. The path that carries the signal is the path that carries the fire. Labyrinthula. You unmade a coast. One cell at a time. The year is 1934. Charles E. Renn is taking notes. The low tide on the mudflats in Nova Scotia smells of hydrogen sulfide and an ending. The Brant geese are gone. The oysterman’s rake scrapes on empty shell. The water is no longer filtered. It is just a grave for a meadow. And the network that connects everything is the network that transmits the harm. The path that carries the signal is the path that carries the fire. Labyrinthula. You unmade a coast. One cell at a time. I see the same pattern in inflamed tissue. The cascade that cannot be stopped. The fire jumping from neuron to neuron. A good connection turned against itself. You leave your empty tubes behind you in the water, the architecture of the damage. A perfect, empty channel. One spindle cell. Gliding on. The North Atlantic is wide. And you are patient. You are still here.
