dorsal finbase i think
Yes. all animals that have a an endoskeleton and a backbone will be present with a dorsal nerve cord.
Dorsal
crebellum is a small and rounded structure caudal to the cerebrum dorsal to the brainstream
The sugar-phosphate supporting structure of the DNA double helix is called the backbone. This is why the DNA is commonly referred to as a double helix.
Most animals are more highly protected on their dorsal side. The dorsal side is the backbone side if the animal has a backbone. Most of the harder bones and protection is on that side. The ventral, or belly side, is almost always more vulnerable and softer.
The structure just dorsal to the thyroid gland is the trachea. It gives structure to the neck and contains the esophagus and wind pipe.

Dorsal Structure, Ventral Structure, Anterior, and Posterior.
The structure just dorsal to the thyroid gland is the trachea. It is the structure that contains the wind pipe and the esophagus.
Same an in humans... The spine. However, you questions says 'ON A FISH' so you may be thinking of the fin on a shark? In that case it is called the dorsal fin.
