Cameras on killer whales record first evidence of joint hunt with dolphins
Scientists have captured rare footage of killer whales and Pacific white-sided dolphins hunting together near the coast of British Columbia, Canada. Despite their common name 'killer whale', orca are actually the largest species of dolphin. The findings, published in the journal Nature Scientific Reports, is the first recorded evidence of the two working together, according to researchers. They studied the mammals using drones and camera tags to understand feeding behaviour. "Not only were the killer whales orienting [themselves] towards the dolphins at the surface, but when the dolphins started to dive, our tagged killer whales would start to dive," lead researcher Dr Sarah Fortune from Dalhousie University in Canada said

About Truth Blocks

Truth blocks are minimal argument units that represent atomic reasoning. Each block is analyzed independently for:

  • Truth Score: Factual accuracy (0-1)
  • Reasoning Types: Deductive, inductive, etc.
  • Logical Fallacies: Detected reasoning errors
  • Confidence: AI certainty in analysis

The weighted score combines truth score with reasoning quality and fallacy penalties according to our scoring criteria.
