This project will analyze the systematics and revise the taxonomy of onchidiid slugs (Mollusca, Gastropoda, Pulmonata). Onchidiid slugs are unique within gastropods for their ecological diversity - including species that live in the sea, fresh water, and on land. As such, research on Onchidiidae will provide a unique opportunity for this project to study general evolutionary transitions between aquatic and terrestrial habitats and between closely related species. Total species diversity and distribution are currently unknown (147 species have been described worldwide, most of which in the tropical Indo-West Pacific), and will be documented here with a new taxonomic revision based on both morphological and molecular data. Field expeditions will provide fresh material for systematic and ecological analyses. Results will be published as articles and monographic revisions, as well as taxonomic identification keys.Research and education will be integrated through a series of innovative activities involving undergraduate students from the host institution. One PhD student and at least two undergraduate students will be trained in field collecting, anatomical dissection, Scanning Electron Microscopy, molecular systematics, and theoretical issues in taxonomy. Enhanced onchidiid systematics will be beneficial to scientists from different fields - for example, physiologists using onchidiids as a model to study photoreception, and conservation biologists using onchidiid slugs as a keystone indicator of the diversity and ecology of heavily-threatened coastal habitats.

该项目将对兰花蛞蝓（软体动物、腹足动物、肺动物）进行系统学分析并修订分类法。兰花蛞蝓因其生态多样性而在腹足动物中独一无二，包括生活在海洋、淡水和陆地上的物种。因此，对 Onchidiidae 的研究将为该项目提供一个独特的机会来研究水生和陆地生境之间以及密切相关的物种之间的一般进化转变。总物种多样性和分布目前未知（世界范围内已描述了 147 个物种，其中大部分位于印度-西太平洋热带地区），并将根据形态学和分子数据进行新的分类学修订，在此进行记录。实地考察将为系统和生态分析提供新鲜材料。结果将以文章和专题修订版以及分类学识别关键词的形式发表。研究和教育将通过一系列涉及主办机构本科生的创新活动来整合。一名博士生和至少两名本科生将接受实地采集、解剖解剖、扫描电子显微镜、分子系统学和分类学理论问题的培训。增强的兰花类系统学将有利于不同领域的科学家——例如，生理学家使用兰花类作为模型来研究光接收，而保护生物学家使用兰花类蛞蝓作为严重威胁的沿海栖息地的多样性和生态的关键指标。
