Being eaten by a not very successful grey heron. ID based on the location (the Douro estuary). Although I can't rule out other related flatfish without a closer look, which I never got, Platichthys flesus is the more likely to be found in estuaries or even freshwater in Portugal.

A flatfish is a member of the order (Pleuronectiformes) of ray-finned demersal fishes, also called the Heterosomata, sometimes classified as a suborder of Perciformes. In many species, both eyes lie on one side of the head, one or the other migrating through and around the head during development. Some species face their left sides upward, some face their right sides upward, and others face either side upward.
