根据1990年5月至1995年7月在台湾沃茨所采浮游鱼类样本，探讨叶状幼体之分布与分类。叶状幼体隶属于青蟹科（Scyllaridae）和长尾蟹科（Palinuridae）2科6属13种。在所采集的叶状幼体中，以Scyllarus和Panulirus种类的叶状幼体最为丰富，占总数的90%。台湾沃茨有大量的早期青蟹和龙虾叶状幼体。沃茨全年均未发现中晚期（除末期）的叶状龙虾幼虫，而在沃茨中发现了镰状龙虾幼虫。这说明台湾北方附近海域的所有阶段的青蟹叶状幼体都可能被保留在北方，而中晚期的龙虾叶状幼体则可能从沃茨中被冲走，而次末期和末期幼体则可能返回沃茨。台湾东北部沃茨存在一个反涡旋，这可能与叶状龙虾幼虫经过一个较长的反气旋期后的冲出和返回密切相关。
Distributions and taxonomy of phyllosoma larvae were examined in Taiwanese waters, based on ichthyoplankton samples collected from May 1990 to July 1995. Phyllosoma larvae belonged to the two families Scyllaridae and Palinuridae representing 6 genera and 13 species. Of the collected phyllosoma larvae, those ofScyllarusandPanulirusspecies were most abundant, forming 90% of total numbers. Early stageScyllarusandPanulirusphyllosoma larvae were abundant in Taiwanese waters. Middle to late stages (except the final stage) ofPanulirusphyllosoma larvae were absent from the waters throughout the year, while those ofScyllarusphyllosoma larvae were collected in the waters. This suggests that all stages ofScyllarusphyllosoma larvae may be retained in the northern part of the waters around northern Taiwan while middle to late stages ofPanulirusphyllosoma larvae may be flushed out from the waters, the sub-final and final stages then possibly returning to the waters. An anticlockwise eddy existed in the waters off northeastern Taiwan, which may be closely related to flushing out and returning ofPanulirusphyllosoma larvae through a much longer planktonic period.
