Sea Snakes and Their Absence in the Atlantic

Sea snakes, despite being the most common marine reptiles, are absent from the Atlantic Ocean due to evolutionary and environmental factors. They evolved in the Pacific's Coral Triangle and face challenges like cold temperatures and lack of rainwater when attempting to migrate. Geographical barriers, such as the formation of the isthmus of Panama, further prevent their migration. While the Panama Canal offers a potential route, establishing a breeding population in the Atlantic remains unlikely. The video also promotes learning opportunities on Brilliant.org.

What is the most common group of marine reptiles in the ocean?

• Sea snakes

• Marine iguanas

• Saltwater crocodiles

• Sea turtles

Where did modern sea snakes evolve?

• Atlantic Ocean

• Indian Ocean

• Mediterranean Sea

• Coral Triangle in the Pacific

Why is it difficult for sea snakes to migrate to the Atlantic Ocean?

• Large ocean size and unsuitable conditions

• Too many predators

• High salinity levels

• Lack of food

What temperature do yellow-bellied sea snakes require to breed?

• Above 20 degrees Celsius

• Exactly 25 degrees Celsius

• Above 15 degrees Celsius

• Below 18 degrees Celsius

How do sea snakes hydrate themselves?

• By consuming prey

• By drinking rainwater on the ocean surface

• By absorbing moisture from the air

• By drinking salt water

What geographical feature blocked sea snakes from moving between the Pacific and Atlantic Oceans?

• The Great Barrier Reef

• The Sahara Desert

• The Andes Mountains

• The Isthmus of Panama

What human-made structure has reopened a passage between the Pacific and Atlantic Oceans?

• Suez Canal

Why is it unlikely for sea snakes to establish a breeding population in the Atlantic via the Panama Canal?

• Incompatible water temperatures

• Lack of food resources

• Geographical and biological constraints

• Inability to adapt to new environments

What is the main reason sea snakes have not moved to the Atlantic Ocean?
