Euglena gasterosteus is a freshwater euglenoid alga with a spindle-shaped, flexible cell body and chloroplasts enabling photosynthesis in well-lit aquatic environments. It inhabits ponds, ditches, and slow-moving freshwaters rich in organic matter. Like all euglenas, it can switch between autotrophic and heterotrophic nutrition and uses a flagellum for movement in the water column.

Fly Agaric

Among the most iconic and recognizable fungi on Earth, fly agaric mushrooms display striking red caps with white flecked warts across boreal forests of the Northern Hemisphere. Despite their fairy-tale appearance, they contain potent psychoactive compounds including muscimol and ibotenic acid and are moderately toxic. They form critical mycorrhizal symbioses with birch, pine, and spruce trees, exchanging mineral nutrients for carbon and playing essential roles in boreal forest nutrient cycling.
