What to know about Octopuses learn mirror-guided navigation to locate prey

A study from Dartmouth College, published in Current Biology, indicates that octopuses can learn to use mirrors to locate prey outside their direct line of sight. Researchers observed that the animals could infer the location of a stimulus and navigate toward it, suggesting the possibility of internal spatial mapping in invertebrates.

What happened

Octopuses learn mirror-guided navigation to locate prey Lisa Lock Scientific Editor Robert Egan Associate Editor Octopuses are remarkably intelligent creatures, as was demonstrated by Inky the Octopus's famous escape from the National Aquarium of New Zealand…

Why it matters

A new Dartmouth study shows octopuses can use mirrors to find food out of sight, demonstrating spatial cognitive abilities.

Common ground

The results are published in Current Biology.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
