Samneric are a pair of identical twins who are “bullet-headed and have hair like tow.” The two boys or “bigguns” breathe together, grin together and are chunky and vital.
In the novel, Samneric symbolize the weakness of human nature. This is because, when they are pressed, they decide to join the dark side. Throughout the novel, the twins are loyal to Ralph and his group because they felt secure. In the last chapter, as soon as Jack threatens and tortures the two, they change sides and submit to Jack Merridew’s authority and join his tribe. “What d’you mean by coming with spears? What d’you mean by not joining my tribe? … The yelling ceased, and Samneric lay looking up in quiet terror. Roger advanced upon them as one wielding a nameless authority.” This act alone shows weakness and vulnerability on the behalf of Samneric.
Later on, Samneric represent the betrayal aspect of humanity. When Ralph runs away from Jack’s tribe, they inform Jack about Ralph’s position in the jungle. They betray Ralph even though he was loyal to them for such a long time. “You’re sure he meant in there? The twin moaned faintly and then squealed again.” This portrays that Samneric are unfaithful to their former leader, Ralph.
Throughout the novel, Ralph is the motivation for Samneric. Both twins look up to and respect Ralph because he offers them a sense of security. They are promised that all their needs will be provided from the group as long as they did their part, which was to keep the fire lit. However, after Jack threatens Samneric they have no choice but to surrender. "Samneric protested out of the heart of civilization". This conveys that Samneric tried to stay loyal to their motivator in Ralph but had no choice and therefore had to give in to Jack.
Samneric have a very respectable relationship with Ralph, Piggy, Simon and other littluns. Unlike other ‘bigguns’ such as Roger and Maurice, Samneric do not leave Ralph’s tribe. The twins do exactly as Ralph
