dorsals
Fins on top
Dorsals are fins on the back of a fish or other aquatic animal, the structures that cut through the water's surface in shark movies.
The term extends to anything relating to the back or upper surface: dorsals muscles, dorsal vertebrae.
In anatomy and biology, dorsal contrasts with ventral (the front or belly side).
