Orange Roughy

• It is one of the longest-lived vertebrates known: ages of up to 149 years have been determined.
• It does not breed until it is 27 to 32 years old, which means populations take decades to recover from overfishing.
• It was marketed as orange roughy from the 1980s onwards; its earlier name, slimehead, was thought unsellable.
