Colombian Soft-furred Spiny-rat

<em>Diplomys caniceps</em>, the Colombian soft-furred spiny rat, is a rodent in the family Echimyidae found in Colombia. The genus <em>Diplomys</em> is characterised by a pelage that, despite the common name, is relatively soft compared to other spiny rats, with spine-like guard hairs interspersed among the fur. This species is assessed as Data Deficient by the IUCN, indicating that available information is insufficient to determine its conservation status reliably. Data Deficient assessments typically arise when a species occupies remote or poorly surveyed habitats, or when taxonomic uncertainties complicate population estimates. <em>Diplomys caniceps</em> is believed to inhabit tropical lowland and montane forests of Colombia, where it likely feeds on plant material including seeds, fruits, and fibrous vegetation. As a medium-sized terrestrial rodent, it probably serves as prey for a range of forest predators. The lack of ecological and distributional data underscores the need for targeted field surveys. Biological traits of this species remain poorly documented in the scientific literature.

Common bull ray

The common bull ray (<em>Myliobatis aquila</em>) is a large elasmobranch found in the coastal and offshore waters of Denmark, Norway, Portugal, and Sweden, typically inhabiting European marine ecosystems. This species typically occurs in shallow coastal seas, estuaries, and sandy bays, where it forages along the seafloor for benthic prey. The common bull ray has not been formally evaluated on the IUCN Red List. As a member of the family Myliobatidae, it is characterized by its diamond-shaped pectoral disc, long whip-like tail, and prominent forehead. The species often feeds on molluscs, crustaceans, and small fish, using its powerful crushing teeth to break open hard-shelled prey. The common bull ray typically moves in small schools or aggregations during certain seasons, and females give birth to live young following internal fertilization. Biological traits of this species remain poorly documented in the scientific literature.
