Lord C., Bellec L., Dettai A., Bonillo C. & Keith P. 2019. Does your lip stick? Evolutionary aspects of the mouth morphology of the Indo-Pacific clinging goby of the Sicyopterus genus (Teleostei: Gobioidei: Sicydiinae) based on mitogenome phylogeny. Journal of Zoological Sciences and Evolutionary Research, 00, 1-16.
One of the characters used to determine Sicyopterus species is the upper lip morphology. The mouth is used as a secondary locomotor organ and is strongly related to climbing abilities. It also has an important role in the feeding mechanism of these herbivorous species. We have established a molecular phylogeny based on the 13 mitochondrial protein coding genes to discuss the relationship between 18 Sicyopterus species and the mouth morphology can be separated with regards to the molecular phylogeny obtained.
