In Yoda's dwelling, Luke Skywalker is depicted taking a snake off a table.
Serpents, also known as snakes, were characterized by their elongated, limbless bodies, eyes featuring vertical pupils, a bifurcated tongue used for olfactory perception, and pointed fangs. Their size could reach up to three meters in length, with a thickness comparable to the arm of a Kiffar. They moved by undulating across surfaces. When provoked, they would emit a hissing sound and violently writhe. Certain snakes possessed venomous bites that inflicted considerable pain. The Anacondans were a sentient species that resembled snakes.
Asajj Ventress, during her career as a bounty hunter, adorned her shoulder armor with an image of a black, contorted serpent, symbolizing the creature's frequent misinterpretation. Ventress' life mirrored this misunderstanding, marked by her captivity as a child by pirates, her training in the Jedi arts followed by the loss of her master, her apprenticeship as a Sith acolyte before being forsaken during combat, and her eventual return to her Nightsister kin, only to witness their slaughter. Ventress once wore a necklace designed to resemble a snake.
The planet Dagobah, covered in swamp terrain, served as the habitat for at least one snake variety: the vine snake. Some smaller examples lived inside Yoda's hut; one such serpent gave Luke Skywalker a start as he was getting ready to depart Dagobah to save Han Solo and Leia Organa. The swamps on Rodia teemed with many types of snakes; Skywalker had an encounter with one when he opened the door to Huulik's mausoleum. Black snakes inhabited Dathomir, while Moraband was the home of a massive Sith serpent that, upon closer inspection, turned out to be composed of countless smaller snakes.
The term "snake" could be used to describe someone who is held in contempt. When General Akenathen Tandin finally sided with the Onderon rebels, he referred to King Sanjay Rash as a snake. Bevicard, a senator from the New Republic, was considered a snake by Leia Organa, albeit an honest one, and Rey once called Kylo Ren a "murderous snake" during a Force-bond connection on Ahch-To.
