Dense mats of Hydrilla create a microhabitat for the toxic cyanobacteria Aetokthonos hydrillicola, which are eaten by native birds, including coots and bald eagles, which infect the animals with avian vacuolar myelinopathy.

The epiphytic cyanobacteria Aetokthonos hydrillicola primarily grows on Hydrilla verticillata. This cyanobacteria causes avian vacuolar myelinopathy, a fatal neurological disease in birds. This disease has been seen to affect waterfowl and bald eagles.

At least 24 waterbird species were found to congregate in areas with Hydrilla verticillata, potentially exposing them to Aetokthonos hydrillicola. This list includes herbivores, omnivores, picivours and raptors.

Field

The underside of Hydrilla verticillata leaves were found to harbor Aetokthonos hydrillicola, an epiphytic cyanobacteria associated with avian vacuolar myelinopathy (AVM). Essentially, aquatic plants and epiphytic algae are primary food sources for coots, which subsequently become sick and consumed by other species like bald eagles.
