Uracoan grasslands of Venezuela
The Uracoan rattlesnake has a very small territory: the open, lightly-wooded grasslands of the Maturin savannah near Uracoa in northeast Venezuela.
The rattlesnake’s main characteristic is the rattle in its tail which produces a distinctive warning signal. The rattle consists of old scales from the tip of the tail which aren’t discarded when the snake sheds its skin. The rattle starts to develop when the snake sheds its first skin - young animals do not have a rattle.
Good to Know
- In the wild the tip of the rattle can break off meaning that the length of the rattle does not necessarily indicate how many times the snake has shed its skin
- Uracoan rattlesnakes are loners who only get together at mating time.
- They are livebearing animals and give birth to up to 10 young between 120 and 160 days after mating, who can live for up to 15 to 20 years.
