Where is the dorsal fin positioned relative to the body axis in a zebrafish?
Answer
Relatively midway along the body axis
When detailing the fin anatomy, the placement of the dorsal fin is specified. This fin, which sits atop the back of the fish, is located relatively midway along the body axis. It is explicitly stated that it is not situated far toward the tail. This placement is important because, combined with the fusiform body shape, it helps provide good stability while the fish moves forward.
