Tiburón cigarro

The cigar shark, also known as the cookiecutter shark (Isistius brasiliensis), is a small but remarkable shark in the family Dalatiidae, found throughout warm oceanic waters worldwide in tropical and subtropical latitudes. Reaching only 40–50 centimeters in length, it possesses oversized jaws with large, triangular lower teeth arranged in a saw-like series that cut distinctive circular plugs of flesh from much larger prey—including tuna, dolphins, whales, billfish, and even submarine cables and human bodies. It does not kill its prey but instead latches on, rotates its body, and excises a characteristic cookie-cutter-shaped bite. The cigar shark is bioluminescent, emitting a green glow from photophores on its ventral surface that may serve as counter-illumination or to attract prey from below. It undertakes diel vertical migrations, ascending to shallower waters at night and descending to mesopelagic depths during the day. The species is classified as Least Concern by the IUCN, with a vast oceanic distribution and no targeted commercial fishery. It is occasionally taken as bycatch. The geographic epithet brasiliensis refers to Brazil, where early specimens were described, but the species' range is circumglobal in warm oceans. The cookiecutter shark's feeding strategy is one of the most unusual among elasmobranchs.

Clifton's Anguloa, Anguloa cliftonii, is a striking terrestrial orchid in the family Orchidaceae native to the cloud forests of the Andes in Colombia, Ecuador, and Peru. The genus Anguloa, known as cradle orchids or tulip orchids, is celebrated among orchid enthusiasts for its large, tulip-shaped, waxy flowers that rock gently when moved, simulating the movement of a bee—a presumed pollination adaptation. The flowers of Anguloa cliftonii are creamy white to pale yellow, often with pink or rose spotting, and are produced singly on erect peduncles arising from the base of large, pleated pseudobulbs. The plant is a cool-growing epiphyte or lithophyte found in humid montane forest at elevations between approximately 1,500 and 2,500 meters in the Andes. Anguloa species are pollinated by male euglossine bees attracted to fragrant compounds. The cloud forest habitats of the Andes are among the world's most biodiverse ecosystems and simultaneously among the most threatened, subject to deforestation for agriculture, cattle ranching, and coca cultivation. Many Andean orchid species are also threatened by over-collection for the horticultural trade. Anguloa cliftonii is cultivated in specialist collections and is the subject of conservation concern in its native range.
