大眼鳜头骨形态的观察

Morphological Observations on the Skull of Siniperca kneri Garman

通过对大眼鳜头骨的形态学观察表明,大眼鳜头骨由134块硬骨和3块软骨组成,其中脑颅38块,咽颅硬骨96块,软骨3块。同时将大眼鳜头骨与鲈鱼头骨进行了比较分析,两者既具有极大的相似性,又有较为显著的差异。探讨了大眼鳜头骨形态结构与其功能适应性。

Morphological observations on the skull of Siniperca kneri Garman were made. Results suggested that the skull of S. kneri contains 134 pieces of os osseum and 3 pieces of cartilage, including 38 pieces of os osseum in the Neurocranium, 96 pieces of os os-seum and 3 pieces of cartilage in the Splanehnocranium. We also discussed the adaptability of the skull of S. kneri＇s structure to its physiological functions. A comparison of the skulls between S. kneri and Lateolabrax japonicus was also made. It is discovered that S. kneri and L. japonicus are similar in many aspects, but there are obvious differences between them in other aspects.
