Colombian Speckled Tree-rat

<em>Pattonomys semivillosus</em>, the Colombian speckled tree-rat, is an arboreal rodent in the family Echimyidae distributed within Colombia. Members of the genus <em>Pattonomys</em> are associated with tropical forest canopy habitats, where their semi-arboreal lifestyle allows exploitation of fruiting trees and epiphytic vegetation. The speckled pelage characteristic of this species likely provides camouflage within dappled forest light. <em>Pattonomys semivillosus</em> is currently listed as Least Concern by the IUCN, reflecting a population not considered to be under immediate threat of significant decline. However, like many forest-dependent Neotropical rodents, this species may be sensitive to deforestation and habitat fragmentation, which reduce connectivity between forest patches and limit access to food resources and mates. The species is presumed to feed primarily on plant matter, including seeds, fruits, and bark. Its ecological role likely includes seed dispersal within its forest habitat. Biological traits of this species remain poorly documented in the scientific literature.

Epaulard

The largest member of the dolphin family, orcas reach up to 9 meters and 6 tonnes and are found in every ocean from Arctic to Antarctic. Apex predators living in matrilineal pods with distinct dialects, hunting strategies, and cultural traditions that differ between populations. Some populations specialize in fish, others in marine mammals. No natural predators; orcas sit at the top of every marine food chain they inhabit.
