common guitarfish

The common guitarfish, <em>Rhinobatos rhinobatos</em>, is a cartilaginous fish belonging to the order Rhinopristiformes, family Rhinobatidae. It is a member of the guitarfish group, characterized by a flattened body with a distinct guitar-like silhouette formed by the fusion of the head, pectoral fins, and trunk. <em>Rhinobatos rhinobatos</em> is assessed as Critically Endangered on the IUCN Red List, representing severe conservation concern and indicating that this species faces an extremely high risk of extinction in the wild. Pressures such as overfishing and bycatch are commonly implicated in the decline of guitarfish species globally. Detailed habitat, range, and country distribution data are not available for this species in current records. No dietary information has been provided for this species. Biological traits of this species remain poorly documented in the scientific literature.

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.
