Dagobah python
From Wookieepedia, the Star Wars wiki.
The Dagobah python was a reptilian predator native to the swamps of Dagobah.
These huge snakes draped themselves over the lowest branches in the planet's jungles, where they waited for a chance to ambush unsuspecting prey. The body of the Dagobah python was virtually all stomach, and it could consume up to fifteen times its own body weight in one feeding.
