Common ray

<em>Telatrygon biasa</em>, the common ray, is a cartilaginous fish in the family Dasyatidae, order Myliobatiformes, belonging to the broader class Chondrichthyes. The species is assessed as Vulnerable on the IUCN Red List, indicating elevated concern over population viability. Common rays are demersal elasmobranchs typically found in shallow coastal and inshore marine habitats, resting on sandy or muddy substrates. Like other dasyatid stingrays, <em>Telatrygon biasa</em> typically feeds on benthic invertebrates including crustaceans, mollusks, and worms, which it detects using electroreceptive ampullae of Lorenzini. It typically moves by undulating its broad pectoral disc, a hallmark locomotion style of stingrays. The vulnerable status of this species likely reflects pressures from bycatch in coastal fisheries and habitat degradation, which are common threats for inshore ray species across the Indo-Pacific region. Biological traits such as lifespan, precise body measurements, and detailed diet composition remain poorly documented for this taxon, and further field research is needed to characterize population structure and reproductive ecology. Conservation measures targeting bycatch reduction in artisanal and commercial fisheries would benefit this species.

Speckled Hummingbird

A medium-sized hummingbird with speckled or spotted underparts — unusual among hummingbirds dominated by plain or iridescent plumages — speckled hummingbirds inhabit cloud forest and forest edges in the Andes from Colombia and Venezuela south to Bolivia at elevations of 900–3,000 meters. The spotted underpart pattern provides remarkable camouflage when the bird perches on lichen-covered bark. They forage on nectar and small arthropods and are important pollinators of Andean epiphytes.
