How many radials support the Wolf Eel's distinct dorsal fin?
Answer
Between 228 and 250 flexible fishbones.
The dorsal fin of the Wolf Eel differs significantly from the continuous fin structure found in true eels. While it runs nearly the entire length of the body, its support system is detailed and specific. This long dorsal fin is supported internally by a substantial number of flexible fishbones, which are technically referred to as radials. The reported range for these supporting structures is quite specific, counted to be between 228 and 250 individual radials. These numerous, flexible supports allow the long fin to undulate effectively for locomotion while also maintaining the overall elongated shape, contrasting with the simpler internal anatomy of true eels.
