Active Volcanoes: The Perfect Egg Incubators

The video explores how various animals utilize volcanic heat to incubate their eggs, benefiting from the warmth to speed up embryonic development. Deep sea creatures like skates and octopuses use hydrothermal vents, while terrestrial animals such as the Malleo bird and possibly sauropods use volcanic soils. The video also discusses the risks involved, such as overheating and volcanic activity, and how these strategies have evolved over time.

Why do some animals use volcanic heat to incubate their eggs?

• To speed up embryo development

• To prevent eggs from floating away

• To keep eggs moist

• To avoid predators

What is a unique adaptation of the Malleo bird regarding egg incubation?

• It uses volcanically heated soils

• It uses its body heat to incubate eggs

• It sits on its eggs like most birds

• It incubates eggs in water

How do deep-sea octopuses utilize hydrothermal vents?

• They use them to find food

• They use them for shelter

• They use them to communicate

• They use them to incubate eggs

What is the main reason embryos need a constant temperature during development?

• To ensure proper chemical reactions

• To maintain egg shape

• To prevent dehydration

• To avoid predators

What is a potential risk of using volcanic heat for egg incubation?

• Eggs might get too cold

• Eggs might get hard-cooked

• Eggs might be eaten by predators

• Eggs might dry out
