Sulphur Mollies and Their Wave Behavior

The video explores the wave phenomenon seen in sports and how sulphur mollies, a type of fish, use a similar behavior to avoid predators. These fish live in sulfur-rich waters in Mexico and are vulnerable to bird attacks. By creating wave-like motions, they confuse predators, increasing their survival chances. This behavior effectively doubles the time predators wait to attack, sometimes causing them to move on. The video concludes with a thank you to SciShow patrons.

What is the primary purpose of 'the wave' at sporting events?

• To entertain the audience

• To confuse the players

• To signal the end of the game

• To distract the referees

Where are sulphur mollies typically found?

• In the Great Lakes

• In the Amazon River

• In sulfur springs in Mexico

• In the Pacific Ocean

What challenge do sulphur mollies face in their habitat?

• Low levels of oxygen

• Low levels of hydrogen sulfide

• High levels of oxygen

• High levels of carbon dioxide

How do sulphur mollies respond to the presence of predators?

• By doing the wave

• By hiding in the mud

• By jumping out of the water

• By swimming faster

What initiates the wave behavior in sulphur mollies?

• A change in water temperature

• The presence of a predator

• A lack of food

• The arrival of more fish

What effect does the wave have on predators?

• It makes the predators more aggressive

• It has no effect on predators

• It confuses the predators

• It attracts more predators

How often can sulphur mollies repeat the wave behavior?

• Every 10 seconds

• Every 3 to 4 seconds

• Every minute

• Every 5 seconds

What was observed about the birds' behavior when mollies did the wave?

• Birds became more aggressive

• Birds waited longer to attack

• Birds ignored the fish

• Birds attacked more frequently

What is the main benefit of the wave behavior for sulphur mollies?

• It helps them find food

• It keeps them warm

• It increases their survival rate

• It helps them reproduce
