From the video

Answers: How do different animals adapt to survive harsh conditions and extreme environments?

• Marine iguana foraging in cold water
• Garter snake mating rituals
• Wildebeest migration and calf survival
• Vampire finch parasitism on boobies
• Golden snub-nosed monkey winter survival
• Red crab migration and spawning
• Arctic fox hunting geese eggs
• Bryde's whale cooperative feeding techniques
• Giant river turtle nesting behavior
• Fire ants forming living rafts during floods

What it concludes

• Marine iguanas have only thirty minutes in cold water to forage before their muscles seize up and they drown.
• Male garter snakes outnumber females one hundred to one, and females release pheromones to attract them.
• Only one in ten wildebeest calves survives to adulthood due to high predator density on the plains.
• Vampire finches have evolved to feed on seabird blood to survive on islands with little other food sources.
• Golden snub-nosed monkeys must stock up on calorie-rich pine cones to survive the freezing winter.
• Red crabs migrate in millions to the ocean to spawn, carrying up to one hundred thousand eggs each.
