Twilight Zone Ocean Ecosystem

The video explains the largest animal migration on Earth, occurring nightly in the ocean's Twilight Zone. This area, rich in marine life like squid and jellyfish, is a refuge from predators. These creatures migrate to the ocean's surface to feed on plankton, contributing to the carbon cycle through their waste, known as Marine Snow. However, fishing in this zone could have unforeseen climate consequences.

What is the Twilight Zone in the ocean known for?

• Having a high concentration of plankton

• Being a dark area with many marine animals

• Being the warmest part of the ocean

• Being the sunniest part of the ocean

What role does the Twilight Zone play in the ocean ecosystem?

• It is where most oceanic plants grow

• It is the main source of oceanic oxygen

• It serves as a hiding place from predators

• It is a breeding ground for all marine life

Why do creatures from the Twilight Zone migrate upwards every night?

• To find mates

• To escape predators

• To feed on plankton

• To enjoy the sunlight

What is Marine Snow and why is it important?

• A seasonal phenomenon that occurs in the Arctic

• A type of oceanic snowfall that cools the water

• Waste from marine animals that helps in the carbon cycle

• A rare type of plankton found in the deep ocean

What potential issue arises from fishing Twilight Zone creatures?

• It may increase the number of predators

• It might disrupt the ocean's temperature balance

• It could lead to overpopulation of plankton

• It could have unknown climate impacts
