Aphanocapsa sideroderma is a unicellular cyanobacterium forming colonial aggregates in gelatinous sheaths with iron-encrusted outer layers. It inhabits iron-rich freshwater environments including springs, streams, and wetlands. This photosynthetic bacterium produces energy through oxygenic photosynthesis and contributes to biofilm formation on iron-rich substrates.

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.
