Invertebrate perception: measuring depth intervals through path integration and vision.
A foraging fiddler crab can estimate how close a potential intruder is from its burrow entrance, even when the entrance in the sand is invisible to the crab. Recent work shows that, to assess this depth interval, crabs combine information from vision and path integration in an unusual manner.
