Estivation Adaptations in Amphibians

The video explores estivation, a survival strategy used by animals in hot, dry environments. Unlike hibernation, estivation focuses on conserving water. The African lungfish, West African reed frog, and Australian water-holding frog are highlighted for their unique adaptations. The lungfish creates a mucus cocoon, the reed frog uses iridophores to reflect light, and the water-holding frog stores water in its body. The video concludes with a humorous note on human adaptation and a call to action for supporting a charity.

What is the primary reason animals undergo estivation?

• To conserve water during hot periods

• To find more food sources

• To escape predators

• To migrate to cooler areas

What is the main difference between estivation and hibernation?

• Hibernation is for conserving water

• Estivation occurs in cold climates

• Hibernation occurs during the rainy season

• Estivation is for conserving water in hot climates

How does the African lungfish survive during dry spells?

• By eating more food before the dry season

• By forming a mucus cocoon and breathing air

• By migrating to wetter areas

• By storing water in its scales

What happens to the African lungfish's body during estivation?

• It consumes its own muscle tissue

• It stores fat for energy

• It grows a thicker skin

• It stops breathing entirely

What is the role of mucus in estivation?

• To prevent water loss

• To attract mates

• To aid in movement

• To help in digestion

What unique feature helps the West African reed frog prevent dehydration?

• Its ability to burrow deep into the ground

• Its skin cells containing iridophores that reflect light

• Its capacity to store water in its stomach

• Its habit of staying in shaded areas

How does the Australian water-holding frog prepare for the dry season?

• By storing food in its body

• By soaking up water and burrowing into the mud

• By developing thicker skin

• By migrating to a different habitat

Why is estivation particularly important for frogs?

• They need to escape predators

• They require more oxygen

• They absorb water through their skin

• They need to find new habitats

What is a practical use of estivation knowledge in the Australian outback?

• Tracking animal migrations

• Identifying safe shelters

• Locating water-holding frogs for hydration

• Finding edible plants

What triggers the Australian water-holding frog to wake up from estivation?

• A change in temperature

• The availability of food

• The presence of predators

• Heavy rains
