Invertebrate animals comprise more than 95% of the animal kingdom's species and approximately 40 separate phyla. Yet, invertebrates are an artificial taxon, in which all members simply possess a single negative trait: they lack a vertebral column (backbone). In fact, some invertebrates are more closely related to vertebrates than to their "fellow" invertebrates. For the purpose of this veterinary article, we have elected to review a handful of important groups: Coelenterates, Gastropods, Cephalopods, Chelicerates, Crustaceans, Insects, and Echinoderms. We have primarily included behaviors that may have an impact on clinical case outcome, or be of interest to the veterinary clinician.
无脊椎动物约占动物王国物种的 95%以上，约有 40 个独立的门。然而，无脊椎动物是一个人为的分类群，其中所有成员仅仅具有一个单一的负面特征：它们缺乏脊柱（脊骨）。事实上，一些无脊椎动物与脊椎动物的关系比与它们的“同类”无脊椎动物更为密切。出于本文兽医的目的，我们选择了审查一些重要的群体：腔肠动物、腹足纲动物、头足类动物、螯肢动物、甲壳动物、昆虫和棘皮动物。我们主要包括了可能对临床病例结果产生影响的行为，或者是兽医临床医生感兴趣的行为。
