Juvenile green keelback! Seeing the snake, you may think it is very scary or very poisonous. But it is not at all The snake is extremely calm, polite and innocent. A mixture of yellow and black color on the head of the snake, you will easily identify them. I know lots of people here don't know about innocent snakes! I'm just trying to know them better. So you might save some innocent life! (PS- you might think, that's copy post. Absolutely not. I just saw this snake is non venomous! Screenshot from fb)
