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.

Jirafa

La jirafa (Giraffa camelopardalis) es el animal terrestre más alto de la Tierra, puede alcanzar 5,5 metros de altura y pesar hasta 1.750 kg. Su elongado cuello, que contiene las mismas siete vértebras cervicales que todos los mamíferos, evolucionó para alimentarse de acacias en sabanas y bosques africanos. Animal social que vive en manadas sueltas, se comunica mediante infrasonidos y lenguaje corporal. Clasificada como Vulnerable debido a la pérdida de hábitat y la caza furtiva.
