Conteúdo: | The condition factor is used as an index of the relative fatness of animals in nature. The Caiman crocodilus yacare is found in several habitats of Pantanal. Thus, this study was carried out to determine the relationships between the condition factor of animals of different body size classes and types of habitat. A total of 190 caimans were caught during the dry (sept, throught nov.) from different habitats of Pantanal as follows; fresh water ponds, temporary channels and the Negro river in  the Nhecolandia region; fresh water ponds and artificial roadside ponds inn the Abobral region; and Miranda river in Miranda region of Pantanal of Mato Grosso do Sul, Brazil. The caimans caught were classifed according to their snout vent lenght (SVL) as follow: 1-young, having less then 50 cm SVL; 2-sub-adult, having 51 to 70 cm SVL; and adult, having more than 71 cm SVL. The condition of caimans was measured by relative condition proposed by LeCren (1951). Condition factors of caimans differed significantly between habitats (P>0,05). Caimans from 'Miranda' river had higher condition factors than those in the other habitats, but differed significantly only from temporary channels and ponds of Abobral. Condition factors did not differ significantly among size classes, but the interaction habitat and size class was significant (P>0,05). The young caimans showed highest factor in salt water ponds and the big caimans in 'Miranda' river and artificial roadside ponds.
