El pejerrey californiano

The video explains how the full moon influences certain animals, particularly the Californian silverside fish, which relies on lunar phases for its reproductive cycle. The silverside spawns on land during high tides associated with the full or new moon. Eggs are laid in the sand and hatch during the next high tide, allowing hatchlings to return to the sea. This unique life cycle is intricately linked to the moon's gravitational pull and tidal patterns.

What natural phenomenon is caused by the gravitational pull of the sun and moon?

• Auroras

• Volcanic eruptions

• Tides

• Earthquakes

Where does the Californian silverside fish lay its eggs?

• In freshwater lakes

• On the beach

• In the deep sea

• On coral reefs

During which lunar phases does the Californian silverside breed?

• First quarter and last quarter

• Full moon and new moon

• Waxing crescent and waning crescent

• Eclipse

How long do the fertilized eggs of the Californian silverside remain buried in the sand?

• One week

• Two weeks

• Four weeks

• Three weeks

What happens to the silverside hatchlings after they emerge from the eggs?

• They fly away

• They are eaten by predators

• They stay on the beach

• They are dragged back into the sea
