摘要
为揭示波纹唇鱼(Cheilinus undulatus)骨骼形态特征,作者采用X射线成像法对波纹唇鱼骨骼进行相关研究。研究发现,波纹唇鱼下口位具牙齿,颌骨密度较大,舌颌骨下端具臼齿状结构;脊柱由10枚躯椎和13枚尾椎构成,第1~10枚脊椎骨连接10对腹肋,第6~9枚脊椎骨具椎体横突,第11~22枚脊椎连接12枚脉棘,第1~21枚脊椎骨连接21枚髓棘,第22枚脊椎上脉棘不明显;第2~8枚脊椎可观察到背肋;4块尾上骨(含1块髓棘)和5块尾下骨(含两块脉棘);肩带位于第1~3枚脊椎下方;腰带位于第5枚脊椎骨下方腹面;背鳍位于第5~21枚脊椎骨上方;臀鳍位于第13~19枚脊椎骨下方腹面。研究结果表明,X射线法可以清晰观察波纹唇鱼骨骼,实现无伤化研究珍稀鱼类;为适应在珊瑚礁中穿梭、捕食和增加消化能力,波纹唇鱼具有独特的骨骼构造。波纹唇鱼骨骼的研究丰富了南海珊瑚礁鱼类的研究基础,为其分类及演化提供参考。
To investigate the skeletal morphological characteristics of Cheilinus undulatus,X-ray imaging was used.The study found that the lower mouth of Sumei fish has teeth,the jawbone density is high,and a molar-like struc-ture is present at the lower end of the hyomandibular bone.The spine comprises 10 trunk vertebrae and 13 coccy-geal vertebrae,and vertebrae 1–10 connect 10 pairs of abdominal ribs.Vertebrae 6–9 have transverse processes of the vertebral body,vertebrae 11–22 are connected with 12 medullary spines,vertebrae 1–21 are connected with 21 medullary spines,and the 22nd vertebral spines are not apparent.Dorsal ribs can be observed in eight vertebrae.There are four supracaudal bones(including one medullary spine)and five infracaudal bones(including two vein spines).The shoulder girdle is below vertebrae 1–3,and the girdle below vertebra 5.On the ventral surface below the vertebrae,the dorsal fin is located above the vertebrae 5–21,and the anal fin is located below vertebrae 13–19.The results of the study reveal that the X-ray method can be used to clearly observe the skeleton of Sumei fish and realize noninvasive studies of rare fish.Sumei has a unique skeletal structure that allows it to adapt to shuttling and preying and to increase digestion in coral reefs.The study of the skeletal structure of Sumei fish enriches the re-search foundation of coral reef fishes in the South China Sea and provides a reference for their classification and evolution.
