Smilosicyopus leprurus (Teleostei: Gobiidae) is a Fin-eater.

ABSTRACT: Ying-Tzu Lu, Min-Yun Liu, You He, and Te-Yu Liao (2016) Smilosicyopus leprurus is a small goby distributed in the Ishigaki Island and Taiwan. Hobbyists found S. leprurus attacked on the caudal fin of fishes kept together. In this study we investigate whether this fin-eating behavior occurs in the field and whether S. leprurus can be considered a fin-eater. Behavior observation in a tank showed S. leprurus snapped off a piece of fins and swallowed. Among S. leprurus preserved immediately after capture, a fin fragment and a few scales were recovered in the gut of a specimen and DNA barcoding shows the fin fragment belonging to Sicyopterus japonicas. The fin-eating behavior of S. leprurus occurs in captivity and in the wild. In addition, the 3D renderings of oral jaws of S. leprurus were provided. Oral teeth are numerous and arranged in close proximity to each other all together like a bladed dentition, which may provide the capability to shear the fin of its prey. The present study shows S. leprurus a fin-eater despite not feeding exclusively on fins.

Project description:BackgroundOceanography and life-history characteristics are known to influence the genetic structure of marine species, however the relative role that these factors play in shaping phylogeographic patterns remains unresolved. The population genetic structure of the endemic, rocky shore dwelling Caffrogobius caffer was investigated across a known major oceanographic barrier, Cape Agulhas, which has previously been shown to strongly influence genetic structuring of South African rocky shore and intertidal marine organisms. Given the variable and dynamic oceanographical features of the region, we further sought to test how the pattern of gene flow between C. caffer populations is affected by the dominant Agulhas and Benguela current systems of the southern oceans.ResultsThe variable 5' region of the mtDNA control region was amplified for 242 individuals from ten localities spanning the distributional range of C. caffer. Fifty-five haplotypes were recovered and in stark contrast to previous phylogeographic studies of South African marine species, C. caffer showed no significant population genetic structuring along 1300 km of coastline. The parsimony haplotype network, AMOVA and SAMOVA analyses revealed panmixia. Coalescent analyses reveal that gene flow in C. caffer is strongly asymmetrical and predominantly affected by the Agulhas Current. Notably, there was no gene flow between the east coast and all other populations, although all other analyses detect no significant population structure, suggesting a recent divergence. The mismatch distribution suggests that C. caffer underwent a population expansion at least 14,500 years ago.ConclusionWe propose several possible life-history adaptations that could have enabled C. caffer to maintain gene flow across its distributional range, including a long pelagic larval stage. We have shown that life-history characteristics can be an important contributing factor to the phylogeography of marine species and that the effects of oceanography do not necessarily suppress its influence on effective dispersal.
