Capture myopathy in a wild Clymene dolphin () stranded alive on the coast of Ceará State, Brazil.

Stranded cetaceans face critical illnesses and often present with multiple co-morbidities, which are further exacerbated by the stress induced by stranding events and interactions with humans. Capture myopathy (CM) is a common condition in dolphins and other wildlife subjected to extreme stress during capture, handling, or transportation. This condition is particularly problematic in highly sensitive species such as dolphins, whose intense physiological response to stress can lead to severe complications. In this case report, we present the hematological, biochemical, and histopathological findings that contributed to the diagnosis of secondary CM in a wild Clymene dolphin, , stranded alive on a beach in northeastern Brazil.
