The video explores the heart structures of various fish, starting with jawless fish like hagfish and lampreys, highlighting their primitive features. It then compares these with the more advanced heart structures of jawed fish, including sharks and bony fish, noting the presence of coronary vessels and valves. The video concludes with lungfish, which show evolutionary traits leading to tetrapods, such as partial atrial separation.
