摘　　要：The morphology, microstructure and demographic parameters of statolith of Sthenoteuthis oualaniensis were studied from 90 individuals captured in the central South China Sea in September and October, 2012. The marphologic results showed that the statolith has great lateral dome and wing dome, small dorsal dome, and long narrow rostrum dome. S. Oualaniensis could be divided into three populations by statolith morphology in the central South China Sea. Five most important featured parameters including total statolith length （TSL）, wing length （WL）, maximum width （MW） were described by logarithmic functions with mental length （ML） （P 〈 0.05 ） ; rostnnn length （ RSL）, dorsolateral length （DLL） were described by linear functions with ML（ P 〈 0.05 ）. With the squid growth, the size of statolith gradually develops, while the ratio of each featured parameter to ML slowly decreases, the ratio of DLL, LDL, RSL and WL to TSL almost remain the same level, corresponding to 48.05%, 60.05%, 35.44%, 67.59%, and the ratio of LDL and WL to SL show little higher.The morphology, microstructure and demographic parameters of statolith of Sthenoteuthis oualaniensis were studied from 90 individuals captured in the central South China Sea in September and October, 2012.
