对冠齿科的骨学和肌学检查揭示了一些非同形的特征(例如，双头腭骨，大的骨盆放射状，骨鳍线内侧的外轴肌肉插入，后提内肌插入第三鳃上)。通过重新评估用于定义沙棘亚目的基本特征，检验了长齿科和叉齿科关系的证据。长齿科被从沙棘亚纲中移除，叉齿科的姐妹关系被拒绝。在研究了几种可能的替代亲缘关系后(Paracanthopterygii，Gobioidei，Callionmoidei，Kurtoidei，Apogonidae，Blennioidei，Trichodontidae)，香槟科被推测为鹈鹕亚目Scorpaenoidei的成员。这一假说很大程度上是基于顶棘的突触构型，顶棘有一个通向颞上感觉管的开口，香槟和一些蝎子样物质是一种独特的条件。一种共有的I型轴外肌形态，在脊椎背鳍翼状突起的远端有单独的纤维插入，这是不寻常的，可能起源于Percias。虽然这些特征都不是这些分类群所特有的，但长齿类也与一些蝎子样的5型棘状鳞和Baudelot‘s韧带起源于第一椎体而不是枕基骨具有相同的特征。在鞭虫科的顶端出现封闭的感觉管，这表明它们的关系也可能与蝎子亚目有关。关于从沙鼠亚纲中去除香槟皂苷的争论同样适用于沙棘亚纲中的切马里西科、指足鱼科、竹节鱼科、毛鱼科、克里迪亚科、卡斯莫多迪科和nototheniods的假设成员。将这些分类群包括在Trachinoidei中没有得到很好的支持，它们的关系需要进一步调查。
An examination of the osteology and myology of the Champsodontidae reveals a number of, apomorphic features (e.g., double-headed palatine, large pelvic radial, expaxial muscle inserting on the medial pelvic-fin ray, posterior levator internus inserting on the third epibranchial). The evidence for a Champsodontidae/Chiasmodontidae relationship is examined through a re-evaluation of the basal characters used to define the suborder Trachinoidei. The Champsodontidae are removed from the Trachinoidei and a chiasmodontid sister relationship is rejected. After investigation of several possible alternative relationships (Paracanthopterygii, Gobioidei, Callionymoidei, Kurtoidei, Apogonidae, Blennioidei, Trichodontidae), champsodontids are hypothesized to be members of the perciform suborder Scorpaenoidei. This hypothesis is based largely on the synapomorphy of a parietal spine with an opening for passage of the supratemporal sensory canal, a unique condition of champsodonitds and some scorpaenoids. A shared Type 1 expaxial muscle morphology, with separate fibre insertions on the distal tips of the spine-bearing dorsal-fin pterygiophores, is unusual and probably derived among perciforms. Champsodontids also share with some scorpaenoids Type 5 spinoid scales and the origin of Baudelot's ligament from the first vertebra rather than the basi-occipital, although neither of these features is unique to these taxa. The occurrence of an enclosed sensory canal on the parietals of Trichodontidae suggest that their relationships might also lie with the Scorpaenoidei. Arguments pertaining to the removal of champsodontids from the trachinoids apply equally to the hypothesized membership of the Cheimarrichthyidae, Pinguipedidae, Percophididae, Trichonotidae, Creediidae, Chiasmodontidae, and notothenioids in the Trachinoidei. Inclusion of these taxa within the Trachinoidei is not well-supported, and their relationships require further investigation.
