Eunotia elegans is a pennate diatom in the family Eunotiaceae, distinguished by its arcuate (curved) frustule with a short, marginal raphe at each pole. It inhabits acidic, soft-water lakes, peat bogs, and oligotrophic freshwater environments where it contributes to periphyton communities. The genus Eunotia is considered a useful indicator of water acidity and low ionic conductivity.

Gray/Purple Heron

A large, elegant wading bird reaching up to 1 meter in height, gray herons inhabit wetlands, rivers, lakes, and coastal areas across Europe, Asia, and Africa. Patient, solitary hunters, they stand motionless for long periods before striking fish, frogs, and small mammals with lightning-fast dagger bill strikes. They nest colonially in tall trees in rookeries called heronries, sometimes shared with other colonial waterbirds. Widely distributed and of Least Concern globally.
