queixado
"Queixado" refers to a person or animal with prominent jaws or to something related to the jaw.
In this sentence, 'queixado' refers to a prominent jaw, which is a characteristic attributed to the fish being described.
O pescador descreveu o peixe como um grande queixado.
The fisherman described the fish as a large jaw.
In this context, 'queixado' conveys a figurative sense of being stunned or speechless, akin to having one's jaw metaphorically dropped.

Here, 'queixado' again denotes a physical jaw, emphasizing a distinguishing feature of the animal.
