厦门港的中华白海豚Ⅱ.颅骨、耳骨及舌骨
Chinese white dolphin (Sousa Chinensis) in Xiamen Harbour Ⅱ. Skulls, ear bones and lingual bones
【摘要】 对厦门海域5头成体(9~30岁)、6头哺乳期幼仔的中华白海豚颅骨、耳骨及舌骨进行了比较研究。5头成体标本的颅骨都已完全骨化缝合,而幼仔的颅骨都基本未愈合。成体、幼仔的耳骨大小和形状都基本一样,表明耳骨的生长和发育与头骨的发育是非同步的。
【Abstract】 Comparative study was conducted between 5 mature Chinese white dolphins (Indo-Pa cific Hump-backed Dolphin, Sousa chinensis, 9~30 a old) and 6 newborn dolphins from Xia men. The skulls of mature dolphins have nearly fused together but those of newborn dol- phins basically keep separate. There is no big difference between the ear bones of mature dolphins and newborn dolphins in size and shape, which indicates that the development of ear bones is non-synchronous as that of the skull. Also, the measurements of the skulls of 5 ma ture Chinese white dolphins from Hong Kong are included.
