The Angular rough shark (Oxynotus centrina) is a species in the genus Oxynotus. Native to Europe, inhabiting ecosystems characteristic of the region.

A large, elegant wading bird reaching up to 1 meter in height, gray herons inhabit wetlands, rivers, lakes, and coastal areas across Europe, Asia, and Africa.

They nest colonially in tall trees in rookeries called heronries, sometimes shared with other colonial waterbirds. Widely distributed and of Least Concern globally.
