What temperature can a macaroni penguin exist?

Macaroni penguins are typically found in sub-Antarctic regions and thrive in cold environments, with temperatures ranging from -2°C to 10°C (28°F to 50°F) being ideal for their habitat. They are well-adapted to cold waters and can endure harsh weather conditions, but prolonged exposure to extreme temperatures outside their typical range can be detrimental to their health.
