Colombian spiny rat

<em>Proechimys canicollis</em>, the Colombian spiny rat, is a terrestrial rodent belonging to the diverse family Echimyidae, occurring in Colombia and Venezuela. Spiny rats of the genus <em>Proechimys</em> are among the most species-rich genera of Neotropical rodents, typically inhabiting lowland tropical and subtropical forests, forest edges, and secondary vegetation. The coarse, spine-like hairs that give this group its common name are thought to function as a deterrent against predators. <em>Proechimys canicollis</em> is assessed as Least Concern by the IUCN, suggesting stable populations across its range. This species likely feeds on seeds, fallen fruits, fungi, and invertebrates, and may play an important role as a seed predator and disperser in forest ecosystems. Research indicates that <em>Proechimys</em> species often achieve high local densities in undisturbed forest, making them important prey items for raptors, felids, and large snakes. Habitat loss in northern South America remains a background concern for long-term population stability. Biological traits of this species remain poorly documented in the scientific literature.

Epaulard

O maior membro da família dos golfinhos, as orcas (Orcinus orca) podem atingir até 9 metros de comprimento e 6 toneladas, sendo encontradas em todos os oceanos, do Ártico ao Antártico. Predadores de topo que vivem em grupos matrilineares com dialetos distintos, estratégias de caça e tradições culturais que diferem entre populações. Algumas populações se especializam em peixes, outras em mamíferos marinhos. Sem predadores naturais, as orcas ocupam o topo de todas as cadeias alimentares marinhas que habitam.
