Story summary
- Dartmouth College researchers reported that octopuses can learn to use mirrors to locate hidden food.
- Three two-spot octopuses required about 10–12 trials before they stopped approaching their reflection and moved toward a virtual crab.
- In testing they chose the correct side 73 % of the time even after a 180° turn.
- Lead author Mary Kieseler said the finding suggests convergent evolution of spatial cognition, implying octopuses may have internal maps.
