This is a wet specimen bull shark heart. It has gone through the formalin fixation process and has been stored in a glass jar with a screw top lid. The jar stands 4 inches tall.
Due to postal regulations, this specimen will be shipped without liquid. It will need to be topped off with a 70% Isopropyl alcohol upon arrival.
I do not harm or kill any animals. They come to me already perished. My job is to re-purpose them and give them life after death.
