I have seen 2 headed snakes before so that isn't unusual(well it is but after color mutations, I think this is the most common snake mutation) but this snake that I am designing for the Kepler Bb planet and planning to have in the story not only has 2 heads but is venomous. And it has 2 rattles. Each rattle is individually controlled. I am thinking of calling this a double rattlesnake but that isn't very creative. I mean it describes the snake but it isn't very creative of a name.
The snake kind of looks like this rattlesnake:
Except it lives in forests and grasslands, not the desert and as I said above it has 2 heads and 2 rattles.
There are 2 movements here commonly used by rattlesnakes. There is the concertina movement(coiled up and striking really far(up to half its body length) is an example of the concertina movement in action). There is also the sidewinding movement which as far as I know is only used by 1 type of rattlesnake, the sidewinder(though sidewinder can also mean the desert adder which isn't a rattlesnake at all).
Anyway what is a good species name for this 2 headed, 2 rattled, venomous snake?
