Octopuses of the near-shore and open-ocean marine realm are ecologically diverse but poorly known taxonomically. Species and genera are usually discriminated by external features of morphology that may well represent convergences in styles of predation. Dr. Voight will conduct intensive histological studies of arm musculature and digestive tract organs to describe these systems in detail and thus acquire new characters for taxonomic comparison and phylogenetic analysis. Special emphasis is placed on arm muscles, suckers, esophageal crop, gills, and salivary glands and ducts. %%% In a research planning grant Dr. Voight will begin intensive histological studies of the arm musculature and digestive system of octopuses of the world. The goal is to describe these systems in detail and thus acquire new taxonomic characters for the recognition of species and genera, and eventually for inferring phylogenetic relationships among the ecologically diverse groups of near-shore and open-ocean octopods.

近岸和公海海洋领域的章鱼具有生态多样性，但分类学方面却知之甚少。 物种和属通常通过形态的外部特征来区分，这些特征很可能代表捕食方式的趋同。 沃伊特博士将对手臂肌肉组织和消化道器官进行深入的组织学研究，以详细描述这些系统，从而获得用于分类比较和系统发育分析的新特征。 特别强调手臂肌肉、吸盘、食道嗉囊、鳃、唾液腺和导管。 %%% 在一项研究计划拨款中，沃伊特博士将开始对世界上章鱼的手臂肌肉组织和消化系统进行深入的组织学研究。 目标是详细描述这些系统，从而获得新的分类学特征，用于识别物种和属，并最终推断近岸和公海章鱼生态多样化群体之间的系统发育关系。
