Why haven't penguins colonized the Arctic?

• Too cold temperatures

• They have already colonized it

• Geographical and biological barriers

• Lack of food sources

What adaptation do Galapagos penguins have for the tropics?

• Thicker feathers for warmth

• Feet flippers for heat exchange

• Longer wings for better flying

• Smaller size to avoid predators

What is the 'Penguin Paradox'?

• Penguins are both predators and prey

• Adapting to new climates makes penguins lose their cold-weather adaptations

• Penguins can't survive in warm climates

• Penguins can fly but choose not to

Why are penguins not found in the Arctic, according to the 'happy' explanation?

• They prefer the Southern Hemisphere

• Lack of suitable nesting sites

• Geographical distance and environmental barriers

• Absence of fish to eat
