Cyanobacteria

A still freshwater lake where tapegrass, sagittaria, and Amazon sword build submerged canopy above a sand substrate grazed by crayfish, snails, amphipods, and shrimp, with the food web actively rebuilding after the removal of the lake's only fish in April 2026.

A damp freshwater shoreline where ludwigia, dollarweed, and sedges root in moist sand along the glass edge of the lake, sheltering amber snails, bladder snails, baby crayfish, ants, worms, and visiting crabs in a nursery and corridor zone between the water and the terrestrial habitats above.
