棱皮龟的大体解剖

Anatomy of Several Systems in Leatherback Turtle

对1例渔民误捕死亡的棱皮龟循环系统、消化系统、呼吸系统和泌尿生殖系统进行了解剖观察。主要特点有：心脏位于胸部正中位置；食管内壁有许多锥状突起，可能起过滤、辅助吞咽食物的作用；肠长360．0cm，占整个消化管长度的51．9％；卵巢形似鸡冠花花瓣，大约有4～6万个未成熟卵细胞，推测为一少年龟。

We have anatomized a juvenile leatherback turtle, Dermochelys coriacea. The heart is located within chest just on midline. The esophagus is lined with papillae that are sharp and keratinized to help swallowing food. The length of the small intestines is 360. 0 cm,which is proportionally 51.9% of the whole gastrointestinal tract. Like cockscomb, the ovary are comprised by 40 - 60 thousands immaturity egg cells.
