This robotic leaf fish may not look scary to you, but then you're not a zebrafish
The "drunk" zebrafish also showed little response to a facsimile of another one of their predators, the heron
With some help from a robotic fish, scientists have discovered that zebrafish are much like humans in at least one way – they get reckless when they get drunk. OK, “drunk” might not be technically accurate, but when exposed to alcohol, the fish show no fear of a robotic version of one of their natural predators, the Indian leaf fish. When they’re “sober,” they avoid the thing like crazy. The researchers believe that the experiments indicate a promising future for robots in behavioral studies.
