corona de Cristo

The Christ plant (Euphorbia milii) is a woody succulent shrub in the family Euphorbiaceae, native to Madagascar. It is one of the most popular ornamental succulents globally, widely cultivated for its bright floral bracts — actually modified leaves surrounding small, inconspicuous true flowers — which appear in red, pink, yellow, or white in wild and cultivated forms. The stems are densely covered with stout spines, contributing to another common name, crown of thorns, derived from the legend that Jesus's crown of thorns was made from this species, though the plant is native to Madagascar and this association is symbolic rather than historical. Euphorbia milii is extremely drought-tolerant and thrives in warm, dry conditions with minimal watering, making it well suited to indoor cultivation and tropical to subtropical outdoor gardens. Like all Euphorbia species, it produces a milky latex sap that is irritating to skin and toxic if ingested, requiring careful handling. The species is a member of one of the largest and most diverse plant genera, Euphorbia, which spans succulents, shrubs, and trees across multiple continents. In Madagascar, wild populations are affected by ongoing deforestation, though the species is widespread in cultivation globally.

Oso Polar

El mayor carnivoro terrestre de la Tierra, el oso polar puede superar los 700 kg y se encuentra en el hielo marino del Artico, desde Canada hasta Rusia. Es un mamifero marino altamente especializado que depende del hielo marino para cazar focas anilladas y barbadas. Excelente nadador capaz de cubrir grandes distancias en agua abierta. Clasificado como Vulnerable, sus poblaciones soportan una presion severa por la rapida perdida de hielo marino artico debida al cambio climatico.
