Two Headed Snakes
Two-headed snakes are very rare creatures, but not unheard of. Life is very difficult for such snakes. First, the two heads have to decide they are both hungry at the same time, and then they have to agree to pursue the same prey. Then they might fight over which head gets to swallow the prey. To make it even more complicated, sometimes one head will attack, and try to swallow its second head. This did happen at the San Diego Zoo some years back, and the snake died.
Blue Mover
The blue tongued skink has a blue tongue which it constantly flicks in and out. Therefore, it is known as the blue mover. The blue mover looks clumsy, but it can move quickly. The blue mover gives birth to live young.
