Appearance and Characteristics In the first edition of The Hobbit, Tolkien made no reference to his size, leading several illustrators to portray him as being very large. Tolkien realized the omission, and clarified in later editions that he was of average hobbit size and in "The Lord of the Rings", there is a reference to Sam being "little less in height" than he is. Tolkien describes Gollum as either dark, bone-white or sallow (pale yellow): at one point, the Men of Ithilien mistake his silhouette (seen from a distance) for a tailless black squirrel. Gorbag and Shagrat describe him as a dark fellow. In a manuscript written to guide illustrators to the appearance of his characters, Tolkien explained this by saying that Gollum had pale skin, but wore dark clothes and was often seen in poor light. The Hobbit states he has pockets, in which he keeps a tooth sharpening rock, goblin teeth, wet shells, and a scrap of bat wing. Despite these details, he is generally depicted wearing a loincloth or naked in illustrations and adaptations. In the Jackson adaptation of The Two Towers, Faramir describes him as "having an ill-favored look." He was also very thin and only had six teeth, comparing him to Shelob; one of the orcs describes him as "rather like a spider himself, or perhaps like a starved frog." Gollum's toughness is said to stem from his hobbit roots. Gollum hates light, and avoids it if possible. He is emaciated and gaunt, but possesses a vicious, wiry strength; Aragorn states, "his malice gives him a strength hardly to be imagined." In The Two Towers, Gollum's grip is described as "soft, but horribly strong" as Gollum wrestles with Sam Gamgee. He is also able to climb effortlessly straight down cliffs impossible to climb by Sam and Frodo, and can make long leaps. Additionally he can run extremely fast, strangely on all fours. Gollum prefers to eat meat raw, and refuses to eat anything Elvish because it apparently burns him to the touch.
Sméagol's appearance and characteristics
Sméagol was a brown-haired Hobbit who soon was consumed by the One Ring and became known as Gollum because of the displeasing gargling sound he made with his throat. Some suggest that he was a river hobbit, enjoying activities like swimming and diving. So, as well as being remarkably similar to a hobbit, it is likely that his physical appearance included subtly webbed fingers and toes and other such things that would make it easier for a hobbit to enjoy swimming in the rivers.
