摘要
对厦门5头中华白海豚成体和6头哺乳期的幼仔,进行齿的形态、齿式、内部构造和磨损情况的研究;根据齿的切片判断年龄,5头成体9~30岁,年龄大小和体表颜色及齿的磨损程度密切相关。出生后的幼仔齿包埋在齿龈中,其齿数、齿式和成体一样。
Five mature Chinese white dolphins (Indo-Pacific Hump-backed Dolphin) and 6 new born dolphins were found dead in Xiamen, and the morphology, number, distribution style, inner structute and wear condition of the teeth are studied. According to the slices of teeth, the age of 5 mature dolphins are concluded-9~30 a old. The ages of dolphins relate to body color and wear level of the teeth. The newborn dolphin's teeth are buried in the gum. The tooth number and distribution style of newborn dolphins are the same as those of the mature ones.
