New research on Blind cave fish has found that they can put even dogs to shame in the intelligence stakes.
Dr Theresa Burt de Perera, an ethologist at Keble College Oxford, studied the behaviour of the Mexican Blind cave fish, Astyanax fasciatus, which in the absence of working eyes, relies on minute changes in pressure to detect the presence of objects in the water.
By using the sensitive lateral line system to detect changes in pressure, they're able to swim around without banging their heads against the glass, rocks or other fish. Blind cave fish swim much more quickly when they are faced with landmarks, like rocks, which they haven't encountered before, presumably to enhance lateral line stimulation.

Anyone know where can I find this paper
