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.

Scarlet Macaw

One of the most brilliantly colored birds in the Americas, scarlet macaws display vivid red, yellow, and blue plumage with wingspans reaching 1 meter. Found in humid lowland forests from Mexico to Bolivia, they are highly intelligent, long-lived — up to 75 years — and form lifelong pair bonds. They travel long distances to clay licks where they consume mineral-rich soil to detoxify seeds. Listed as Least Concern but locally threatened by habitat loss and the pet trade.
