Abstract:
The genus Sinocyclocheilus represents the largest freshwater cavefish genus in the
world. This emerging model system is endemic to the southern Chinese karstic
landscape, and demonstrates multiple adaptations for caves (troglomorphism), with
eye-degeneration being the most pronounced. The less-apparent lateral line system,
which is often expanded in cave-dwellers, has been studied in other cavefish systems,
but never in the context of this diversification. Here we investigated the distribution
and evolution of cephalic neuromasts in 26 Sinocyclocheilus species. We used live
staining and behavioural assays, and interpreted results in a phylogenetic context. We
show that asymmetry in neuromast features and the rate of evolution is greater in cave
adapted species. Ancestral state reconstructions show that most Sinocyclocheilus are
right-biased with some scatter, and show convergence of neuromast phenotypes. There
is substantial variation in cephalic neuromast distribution patterns between and (to a
lesser extent) within species. Behavioural assays show blind species have a distinctive
wall-following behaviour. We explain these patterns in the context of the deep
evolutionary history associated with this karstic region, other organismal traits, and
habitat occupation of these remarkable diversifications of fishes. Interestingly, some of
these neuromast patterns and behaviour show convergence with other phylogenetically distant cavefish systems.
Key words: Asymmetry, convergence, ancestral state reconstructions, wall-following
