Coimbra-Filho’s Titi

The Coimbra-Filho's Titi (Callicebus coimbrai), also known as Coimbra-Filho's Titi Monkey, is a small New World monkey in the family Pitheciidae, named in honour of the Brazilian primatologist Adelmar F. Coimbra-Filho. This titi monkey is endemic to the Atlantic Forest of northeastern Brazil, with its range restricted to the states of Sergipe and southern Alagoas—one of the most critically fragmented and threatened biomes on Earth. Adults are small, with reddish-brown fur on the flanks and upperparts, pale grey on the underparts, and an orange-red forehead band. Like all titi monkeys, Callicebus coimbrai is highly social, living in monogamous family groups of 2–5 individuals that engage in elaborate dawn duets and tail-twining behaviour as expressions of pair bonding. The species inhabits Atlantic Forest fragments, including lowland and highland forest patches, riverine gallery forest, and secondary growth, where it subsists on fruits, seeds, leaves, and occasional invertebrates. The Coimbra-Filho's Titi is classified as Endangered by the IUCN due to its severely fragmented range within one of the world's most deforested biomes, with less than 12% of original Atlantic Forest remaining, ongoing habitat loss from agricultural expansion, and small, isolated population sizes highly vulnerable to stochastic extinction events.

Common Hooktail

<em>Paragomphus genei</em>, commonly known as the common hooktail, is a dragonfly in the family Gomphidae. It is classified as Least Concern on the IUCN Red List, suggesting a stable and widespread population. The species is noted to occupy virtually all terrestrial and freshwater habitats within its range, reflecting considerable ecological generalism typical of many gomphid dragonflies. Specific country-level distribution records for this species are not detailed in current data, though the breadth of habitat use implies a relatively wide geographic range across suitable regions. Diet information for this species is not available in current records. Biological traits of this species remain poorly documented in the scientific literature.
