> As there are very different types of animals affected and fishes can travel Maybe slightly worrying also is that it affects both bony fish and cartilaginous fish, which are indeed very different in that (to my understanding) bony fish are phylogenetically closer to humans than to cartilaginous fish. Which doesn't mean humans are necessarily vulnerable to the same problem, but there's no indication we shouldn't be affected as well (although our brains are probably better equipped to deal with internal ear or balance problems in general).
