Adaptations of Sea Snakes

Sea snakes are adept swimmers, having evolved streamlined bodies and paddle-like tails to navigate marine environments. They can dive deep and have unique physiological adaptations, such as extended lungs for buoyancy and oxygen absorption through their skin, allowing them to stay submerged for long periods.

What is a key characteristic of sea snakes that distinguishes them from other snakes in terms of habitat?

• They spend their entire lives in the ocean.

• They are found only in rainforests.

• They live in freshwater lakes.

• They inhabit desert regions.

How have sea snakes adapted their bodies to improve swimming efficiency?

• By flattening their bodies vertically.

• By developing wings.

• By flattening their bodies horizontally.

• By growing fins.

What role do the paddle-like tails of sea snakes play in their swimming?

• They help in steering.

• They store food.

• They increase surface area for more thrust.

• They are used for defense.

What is a unique feature of the sea snake's lung?

• It is used only for buoyancy.

• It is divided into multiple chambers.

• It extends almost the full length of their body.

• It is located in their tail.

How does the elongated lung of sea snakes assist them in water?

• It provides buoyancy control.

• It helps them digest food faster.

• It allows them to see underwater.

• It helps them communicate.

What percentage of their oxygen requirement can sea snakes absorb through their skin?

• 75%

• 10%

• 25%

• 50%

How long can sea snakes remain underwater on a single breath?

• 30 minutes

• 1 hour

• 3 hours

• 2 hours

What adaptation allows sea snakes to stay submerged for extended periods?

• Their ability to slow their heart rate.

• Their ability to hibernate.

• Their ability to absorb oxygen through their skin.

• Their ability to store water.
