Abstract

Abstract Descriptions of the developmental stages of embryonic marine turtles are presented in the form of a dichotomous key supported by drawings to facilitate identifying stages of development in the field. The key emphasizes the sequential appearance or loss of external morphological structures that can be seen either with the unaided eye or with a ×10 hand lens and a handheld light. Stages are placed in the context of normal beach temperatures to facilitate estimation of laying date, emergence date, and events that cause embryonic mortality. Measurements of embryos are presented to assist determining stage.

海龟(龟科)发育阶段的野外关键资料及皮龟发育笔记

摘要海龟胚胎发育阶段的描述以二分键的形式呈现，并辅以图纸，以便于识别该领域的发育阶段。关键是强调外部形态结构的连续出现或丢失，这些结构可以用肉眼或×10手动镜头和手持灯看到。阶段被放置在正常海滩温度的背景下，以便于估计产卵日期、羽化日期和导致胚胎死亡的事件。对胚胎的测量有助于确定阶段。

期刊介绍： Chelonian Conservation and Biology is a biannual peer-reviewed journal of cosmopolitan and broad-based coverage of all aspects of conservation and biology of all chelonians, including freshwater turtles, marine turtles, and tortoises. Manuscripts may cover any aspects of turtle and tortoise research, with a preference for conservation or biology. Manuscripts dealing with conservation biology, systematic relationships, chelonian diversity, geographic distribution, natural history, ecology, reproduction, morphology and natural variation, population status, husbandry, community conservation initiatives, and human exploitation or conservation management issues are of special interest.
