How Giant Creatures Eat Tiny Meals: 5 Fabulous Filter Feeders

The video explores the diverse feeding strategies of ocean giants like blue whales, gray whales, whale sharks, megamouth sharks, and manta rays. It highlights how these creatures efficiently filter tiny organisms from seawater to sustain their massive sizes. Each species has evolved unique methods to maximize energy intake, from blue whales' lunge feeding to manta rays' innovative filtration techniques. These adaptations not only ensure survival but also offer insights into potential human applications, such as improved filtration systems.

Why do large ocean creatures like blue whales prefer feeding on krill rather than larger fish?

• Krill are more abundant than fish.

• Krill are tastier than fish.

• Krill are easier to catch than fish.

• Krill provide more energy per unit than larger fish.

What is the primary feeding strategy used by blue whales to consume krill?

• Ram feeding

• Suction feeding

• Filter feeding

• Lunge feeding

How do gray whales primarily feed on amphipods?

• By chasing them in the open water

• By using their baleen to filter them from the water

• By sucking them out of the sea floor

• By trapping them in their mouths

What adaptation allows gray whales to feed on different types of prey?

• Their ability to dive deep

• Their large size

• Their fast swimming speed

• Their flexible feeding habits

Which filter feeding method is used by whale sharks when they swim with their mouths open?

• Suction feeding

• Ram feeding

• Passive feeding

• Lunge feeding

What unique feature helps megamouth sharks attract prey?

• Their reflective lip strip

• Their fast swimming speed

• Their large size

• Their sharp teeth

How do manta rays prevent their filter plates from clogging?

• By frequently cleaning their plates

• By having larger filter gaps

• By using a special mucus

• By creating whirlpools that keep particles from sticking
