Penguins have special adaptations to prevent their blood from freezing in cold temperatures. They have a high concentration of hemoglobin in their blood, which helps retain oxygen and prevent it from freezing. Additionally, they have a counter-current heat exchange system in their legs to keep their vital organs warm.
