common marmoset

<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.

Lion

The largest wild cat in Africa, lions reach up to 250 kg and are the only social felids, living in prides across sub-Saharan savannas and grasslands. Males are distinguished by their iconic manes. As apex predators, they regulate herbivore populations and maintain ecosystem balance. Listed as Vulnerable due to habitat loss and human-wildlife conflict.
