Dolphin Hunting and Bait Ball Dynamics

The video explores the natural phenomenon of bait balls formed by mackerel to deter predators. Despite this defense, bluefin tuna and dolphins exploit the bait ball to feed. The dynamics of predator-prey interactions are highlighted, including the role of dolphins in tightening the bait ball with air bubbles. Seabirds like shearwaters also join the hunt, leading to the bait ball's rapid decimation. The video concludes with a repetitive emphasis on the tuna's role in this ecosystem.

What is the primary purpose of a bait ball formed by mackerel?

• To attract more mackerel

• To confuse predators

• To migrate to warmer waters

• To find food

Why are bluefin tuna not deterred by the bait ball?

• They see it as a feeding opportunity

• They are not interested in mackerel

• They are too small to be affected

• They are scared of the mackerel

How do dolphins assist in hunting the mackerel?

• By scaring away other predators

• By creating air bubbles to pack the mackerel tighter

• By leading the mackerel to shallow waters

• By eating the mackerel themselves

Which seabirds are mentioned as being able to see the bait ball?

• Albatrosses

• Shearwaters

• Pelicans

• Seagulls

What is the ultimate fate of the bait ball?

• It migrates to a new location

• It is decimated by predators

• It grows larger and attracts more fish

• It becomes a permanent structure
