What anatomical features related to movement and lateral sensing does the adult wolf eel structurally lack?
Answer
Pelvic fins and a lateral line.
The structural composition of the adult wolf eel includes a single, long dorsal fin that extends along the entire length of its body. However, it exhibits specific absences in its anatomy that differentiate it further. Specifically, the adult lacks pelvic fins, which are common features in many fish species used for stability and maneuvering. Additionally, it lacks a lateral line system, which is typically used to sense vibrations and pressure changes in the water. The fish relies instead on its reclusive lifestyle within dens for security.
