摘要
文章采用X光射线法结合生物生态消化法,对高体(Seriola dumerili)个体中轴骨骼进行了消化、拍照及描述性统计。研究发现高体中轴骨骼包括头骨和脊柱,头骨分为脑颅和咽颅两部分,脑颅分为筛区、眼区、耳区、枕区4区及围眶骨系,咽颅分为颌弓、舌弓、鳃弓3区及鳃盖骨系;高体躯干支撑结构为脊柱,脊柱由前后连接的椎骨组成,每节椎骨均由形态不同的椎体、髓棘、髓弓组成,部分椎骨分化出椎体横突、肋骨、脉弓和脉棘。结果表明,高体头部主要骨骼约为128块,其中脑颅(包括围眶骨系) 39块,咽颅(包括鳃盖骨系) 89块;包括尾杆骨在内,高体脊柱椎骨数目为24,脊柱共有髓棘、髓弓23枚,脉棘14枚、脉弓15枚,椎体横突10对,无背肋,腹肋9对。
With X-ray and ecological digestion methods,the axial skeleton of Seriola dumerili were digested,photographed and described statistically.It is showed that the axial skeleton of S.dumerili included skull and spine.The skull was divided into neurocranium and splanchnocranium.The neurocranium was composed of ethmoidal region,orbital region,otic region,occipital region and circumorbital series.The splanchnocranium was divided into mandibular arch,hyoid arch,branchial arch and opercular series.The supporting structure spine was composed of vertebrae connected front and back.All vertebra consisted of centrum,neural spine and neural arch in different shapes.Partial vertebrae differentiated into parapophysis,ribs,haemal arches and haemal spines.The results show that the main bones of skull were about 128,including 39 neurocranium and 89 splanchnocranium.The number of vertebrae of S.dumerili spine was 24,with 23 neural spine,23 neural arch,14 haemal spines,15 haemal arch,10 pairs of parapophysis and 9 pairs of ventral ribs,but without dorsal rib.
