Determining the aspect of the contours of a shape

Hello,
I am trying to automatically detect fishes in an underwater environment. I have this type of image (after having preprocessed the video input):


image description

Clearly the fish shape has less edges than the bottom algae one. Basically what I would like to do is to either be able to get the aspect of my contour or to get the number of edges of each contours to differentiate my fish from my algae.
Do you have any idea of how I could do that using Python ? I am also open to any suggestions on how to differentiate these two shapes without using masks.
Thanks in advance for your answers.
