Video Information and Comprehension Questions

Blue Planet: Coral Seas

The following questions appear onscreen in the video. Feel free to integrate them into your lesson plan as needed.

Part I
Before watching the video, consider this.
  • Cnidarians are the taxonomic group that includes coral, jellyfish, and sea anemones. As you watch the program, think about the physical characteristics of each organism.
  • Pay attention to how these adaptations allow the organism to be both predator and prey in a coral reef ecosystem.
After watching, talk about this.
  • Discuss why coral reefs are described as "both provider for predators and protector of prey." Talk about the methods prey use to avoid predators in the coral reef ecosystem.
Suggested activity
Research the Great Barrier Reef off the coast of Australia. Create a poster that shows the animals that depend on the coral reef for food.
Part II
Before watching the video, consider this.
  • As you watch the program, think about why some organisms in an ocean ecosystem produce hundreds or thousands of offspring.
  • Think about and identify organisms on land that can produce many offspring. Name advantages and disadvantages of this adaptation.
After watching, talk about this.
  • Brown surgeonfish, banded pipefish, cuttlefish, humpback whales, and coral have different methods of reproduction. Compare and contrast their mating behaviors.
  • Evaluate each behavior in terms of its ability to produce the greatest number of living offspring.
Suggested activity
Research one of the organisms you saw in the program. Write a report that includes reproduction methods, eating habits, and lifespan.
