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.

Long-tailed Sylph

One of the most strikingly ornamented hummingbirds, male long-tailed sylphs have iridescent green plumage and dramatically elongated, ribbon-like outer tail feathers reaching up to 22 cm — over three times the body length. Found in Andean cloud forests of Colombia and Venezuela, they inhabit humid montane forest between 1,400–2,800 meters elevation. Males perform elaborate display flights to attract females. Their extravagant tails are a classic example of sexual selection via female preference.
