Sagüi-comum

<em>Callithrix jacchus</em>, the common marmoset, is a small New World primate in the family Callitrichidae, endemic to northeastern Brazil. It is classified as Least Concern on the IUCN Red List. This species typically inhabits tropical and subtropical forests, forest edges, and scrubby vegetation known as caatinga and cerrado, demonstrating considerable adaptability to degraded and fragmented habitats. Common marmosets are social animals that live in cooperative family groups, with all members typically assisting in the care of offspring. They are typically omnivorous, feeding on tree gums, sap, insects, small vertebrates, and fruit. Their specialized lower incisors allow them to gouge bark and extract plant exudates, a dietary specialization that sets marmosets apart from many other primates. The species has been widely used in biomedical research. Common marmosets have also been introduced outside their native range in Brazil, where they can impact native biodiversity through competition and predation on endemic wildlife.

pinguim-imperador

O maior pinguim do mundo, os pinguins-imperadores medem até 1,2 metro de altura e pesam 45 kg, habitando o continente antártico em algumas das condições mais extremas da Terra. Reproduzem-se no meio do inverno, na escuridão, a temperaturas abaixo de -60°C, com os machos incubando ovos únicos sobre os pés sob uma bolsa de criação por 65 dias enquanto as fêmeas estão no mar. Seu comportamento de aglomeração — onde os indivíduos revezam-se pelo centro quente de grupos de milhares — é uma obra-prima de sobrevivência cooperativa.
