mergulhão-colombiano

<em>Podiceps andinus</em>, commonly known as the Colombian Grebe, is a bird species belonging to the genus <em>Podiceps</em> within the family Podicipedidae. This species is classified as Extinct, with the last confirmed sightings recorded in the 1970s at Lake Tota in Colombia, its sole known location. The Colombian Grebe was endemic to Colombia and is believed to have been primarily restricted to that high-altitude lake. A record from Norway in available data likely reflects a historical or erroneous entry rather than a genuine occurrence. The species inhabited various aerial, terrestrial, and aquatic environments in the context of its lake ecosystem, diving for fish and other aquatic prey in the manner characteristic of grebes. Habitat drainage for agricultural purposes, hunting, and pesticide contamination of its lake habitat are considered the primary drivers of its extinction. Dietary information specific to this species has not been documented, though grebes typically consume fish and aquatic invertebrates. Biological traits of this species remain poorly documented in the scientific literature. The extinction of <em>Podiceps andinus</em> is considered one of the notable avian losses of the twentieth century in South America.

common bottlenose dolphin

A espécie de golfinho mais estudada e reconhecida, os roazes habitam oceanos quentes e temperados de todo o mundo, desde águas costeiras rasas até ao mar aberto. Altamente inteligentes com grandes cérebros em relação ao tamanho corporal, demonstram auto-reconhecimento, comunicação complexa e aprendizagem social. Vivem em sociedades fluidas de fissão-fusão e cooperam para arrebanhar peixes. Uma espécie indicadora chave da saúde dos ecossistemas marinhos.
