Favorable conditions always support survival rate of any organisms. Laboratory conditions are favorable in case of instar nymphs of Solifugae. Cannibalism is a common act in the members of class Arachnida. After hatching from the eggs, instar nymphs of Solifugae begin to disperse gradually away. This is essential to avoid competition for food, space and prevent cannibalism among the siblings. The number of juvenile of Solifugae in plastic bottles remains unchanged past one month of separation. All instar nymphs of Solifugae survived in separation but their number was dropped in the association. During our investigations, juveniles of Family Galeodidae were kept on same diets. There was difference in survival rate of juveniles. The result showed that cannibalism is a source of energy for Solifugae for an extensive time and surviving rate were declined in association of juveniles but separation of juveniles supports more chances towards life and survival.
