Questions and Answers

What is the primary method used by researchers to study octopus hunting behavior in the Red Sea?

  • Direct interaction with the octopuses using specially designed equipment.
  • Detailed analysis of pre-existing scientific papers on similar topics.
  • Analysis of captured octopuses and their stomach contents.
  • Observation through underwater footage collected over a series of days. (correct)

    • What behavior suggests the octopus is leading the hunt, based on the study findings?
