Conspecific. Two or more individual organisms, populations, or taxa are conspecific if they belong to the same species. Where different species can interbreed and their gametes compete, the conspecific gametes take precedence over heterospecific gametes. This is known as conspecific sperm precedence, or conspecific pollen precedence in plants. Heterospecific The antonym of conspecificity is the term heterospecificity: two individuals are heterospecific if they are considered to belong to different biological species.
I think it is probably due to anxiety but not sure. Whenever I lay down afternoon or at night I can hear and feel my heart beating. It feels as though there is a sledge hammer in my chest pounding back and forth. It actually feels sometimes like it is making my body move. I can hear and feel every single beat.
I get that same weird quivering in my chest as well. I also get a lot of chest pain and heart palpitations all day long. I've had 3 EKG's, 2 chest x-rays, and blood work; all normal. The quivering doesn't hurt it is just a very weird feeling and very unnerving.
