鱼类中的细菌生物发光器官具有多种多样的起源组织、区室化模式和相关的导光结构。肛周，细菌生物发光器官的Aulotrachichthys prosthemius的形态以前被描述，但光器官在其他物种的史莱姆，家庭Trachichthyidae，知之甚少。在这里，我们描述了在Trachichthyoidei的生物发光器官的解剖和地方的背景下，一个新的生殖系统的Trachichthyoidei的生物发光系统的进化来测试的假设，即生物发光进化两次在亚目和发光组件来自肛周外胚层。我们使用的大体和组织学检查，提供第一次描述的生物发光器官的Paratrachichthys和另外四种Aulotrachichthys。观察还强烈建议存在的肛周生物发光器官Sorosichthys ananasa。更新的Trachichthyoidei的系统发育是第一个联合收割机结合形态和DNA序列（11基因片段）的证据，并支持一个单系Trachichthyidae与组件亚科Hoplostethinae和Trachichthyinae，支持继续承认家庭Anoplogastridae。所有的生物发光的沙眼鱼都有一个类似的生物发光器官结构，细长的腔室充满了细菌，并连接到收集管，收集管又连接到浅表管，导致并具有与表皮连续的衬里上皮。在系统发育的背景下，推测粗鱼类的生物发光器官是由Aulotrachichthys，Paratrachichthys和Sorosichthys的祖先中的肛口进化而来的，独立于Anomalopidae和Monocentridae中结构相似的头部生物发光器官。
Bacterial bioluminescent organs in fishes have a diverse range of tissues of origin, patterns of compartmentalization, and associated light‐conducting structures. The morphology of the perianal, bacterial bioluminescent organ of Aulotrachichthys prosthemius was described previously, but the light organ in other species of slimeheads, family Trachichthyidae, is poorly known. Here, we describe the anatomy of the bioluminescent organs in trachichthyids and places the evolution of this light‐producing system in the context of a new phylogeny of the Trachichthyoidei to test the hypothesis that bioluminescence evolved twice in the suborder and that the light‐producing component derives from the perianal ectoderm. We use gross and histological examination to provide the first description of the bioluminescent organ of Paratrachichthys and four additional species of Aulotrachichthys. Observations also strongly suggest the presence of a perianal bioluminescent organ in Sorosichthys ananasa. The updated phylogeny of the Trachichthyoidei is the first to combine morphological and DNA‐sequence (11‐gene fragments) evidence, and supports a monophyletic Trachichthyidae with component subfamilies Hoplostethinae and Trachichthyinae, supporting continued recognition of the family Anoplogastridae. All bioluminescent trachichthyoids share a similar bioluminescent‐organ structure with elongate chambers filled with bacteria and connected to collecting ducts that, in turn, connect to superficial ducts that lead to and have lining epithelia continuous with the epidermis. In the context of the phylogeny, the bioluminescent organ of trachichthyids is inferred to have evolved as an elaboration of the proctodeum in the ancestor of Aulotrachichthys, Paratrachichthys, and Sorosichthys independently from the structurally similar cephalic bioluminescent organs in Anomalopidae and Monocentridae.
