Table 6 in Evolution in the dark: Unexpected genetic diversity and morphological stasis in the blind, aquifer-dwelling catfish Horaglanis

Table 6. Intraspecific variation in morphometric characters across three different species of Horaglanis from our collection. Comparative material of Horaglanis alikunhii was not available for morphometric analysis.
