Clastidium setigerum is a filamentous cyanobacterium in the family Clastidiaceae, characterized by producing tapering filaments anchored to substrates by a basal holdfast cell. It grows on coarser algae, invertebrates, and rocky substrates in freshwater or marine environments. Its single, hair-like trichome ending in a long colorless hair is a distinctive morphological feature of this genus.

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.
