黄海北部发现的中华白海豚 Ⅱ.脊柱、肋骨、胸骨和肢带骨测定结果
The By-catching Chinese White Dolphins in the North of Yellow Sea Ⅱ.Measurement of Vertebrae, Ribs, Sternums, Scapulas and Fin Bones
【摘要】 前文初步报告了对2003年5月在黄海北部(北纬39°35′01″;东经122°51′50″)误捕的中华白海豚的外形和内脏器官测定结果,本文则报告了对该中华白海豚的脊柱、肋骨、胸骨和肢带骨的测定结果,此中华白海豚脊椎式为:C7+T12+L10+Ca22,与中国沿海其他海区的中华白海豚的骨骼测定结果基本相似。脊椎骨测定结果体现了海豚流线型曲线特点,但样本的第八和第十腰椎的脊突出现了分叉。另外,左第九、十肋骨上也出现了病灶。
