Having not kept long-fin variants before and being in the middle of a deep dive into Polypterus physiology has left me with the title question. While i can tell from the images that the caudal and pectoral fins seem to be extensions of the soft rays, its the internal structure of the dorsal finlets that is less obvious to me. My current assumption is that its just the soft rays in these that are extended rather than the spines. Would love to see if that corresponds to the insight and experience of those more familiar, and if so how it effects the rest of the finlets in turn.
