New 'Closed Species'?

I have no name for them yet
Correct me if i am wrong, but, closed means that that only myself and those with express permission can create correct?

-The chest piece is glass and shows the color of their blood ;3

-They can detach and float 1 foot above their bodies, but while they are this way blood will flow from the upper half into the lower half; even when bending over, almost like a magnet.

-Their eyes are usually solid black but can sometimes have a white highlight

-Wings are not common and cannot be used for flight

Thats about all iv got, any ideas/feedback?
Thank you for looking <3
