There's a Wave Made Out of Fish

The video explores the wave phenomenon, where sulfur mollies, small fish in Mexico, mimic a wave to deter predators. Living in sulfur-rich waters, these fish face oxygen scarcity and predation. Their wave behavior, triggered by predator presence, confuses predators, doubling the time birds wait to attack. This survival tactic is likened to the human wave seen in sports events.

Where are sulfur mollies typically found?

• In Sulphur Springs in Mexico

• In the ocean

• In freshwater lakes in Canada

• In saltwater marshes in the USA

What environmental challenge do sulfur mollies face in their habitat?

• Excessive sunlight

• High levels of carbon dioxide

• Low levels of oxygen due to hydrogen sulfide

• Cold water temperatures

What is the primary reason sulfur mollies perform the wave behavior?

• To confuse predators

• To entertain themselves

• To increase oxygen intake

• To attract mates

How does the wave behavior help sulfur mollies against predators?

• It confuses the predators

• It creates a loud noise

• It attracts larger fish to scare away predators

• It makes them invisible

How often can sulfur mollies repeat the wave behavior?

• Every 10 seconds

• Every 30 seconds

• Once a minute

• Every 3 to 4 seconds
