The larger body shape index gives the fish a longer, shallower body, allowing for a more torpedo-shaped fish, allowing it to glide through the water at a higher velocity. Ecology My biological hypothesis was that fish in streams would have a larger body shape and pelvic fin index because it is more necessary for stream fish to have a morphological figure corresponding to the type of environment that they live in. Also, because lake fish are in standing water, they do not need as torpedo-shaped of figure as those in moving water, such as streams....
