类鲶的特征是存在腭-上颌骨机制，这使得上颌骨触须能够控制移动。在革胡子鲶，个体发育的这种机制进行了研究和描述，以及那些肌肉有关的上颌须。有两种肌肉可以区分：（1）牵开触手，连接上颌骨和悬骨;（2）伸肌触手，从颅骨的腹外侧面延伸到腭的后半部分。这些典型的鲶鱼肌肉来自于广义硬骨鱼中存在的肌肉。据信，牵开肌来源于下颌内收肌复合体的A（3）肌。伸肌由腭弓收肌的前纤维形成。C.腭肌为杆状。gariepinus，并与眶鼻板在幼虫标本和其骨化的外侧筛骨，在少年和成年标本。关节通过自腭骨背面的长软骨带发生，从而使旋转和受限滑动都成为可能。
Siluroids are characterized by the presence of a palatine-maxillary mechanism, which enables a controlled mobility of the maxillary barbels. In Clarias gariepinus, the ontogeny of this mechanism is studied and described as well as those muscles related to the maxillary barbel. Two muscles are distinguished: (1) retractor tentaculi, connecting the maxilla to the suspensorium, and (2) extensor tentaculi, running from the ventro-lateral face of the skull to the posterior half of the palatine. These typical catfish muscles are derived from muscles that are present in generalized teleost fishes. The retractor muscle is believed to be derived from the A(3) muscle of the adductor mandibulae complex. The extensor muscle is formed from the anterior fibres of the adductor arcus palatini. The palatine is rod-like in C. gariepinus and articulates with the orbito-nasal lamina in larval specimens and with its ossification the lateral ethmoid, in juvenile and adult specimens. The articulation occurs via a long cartilaginous strip on the dorsal face of the autopalatine, thereby enabling both a rotation and a restricted sliding.
