This paper has the objective to investigate hematological, serum biochemistry and urinary physiological parameters of the Crab-eating fox, comparing gender and age differences. Blood samples were collected in 2003 from 52 animals of different Zoos in São Paulo state, Brazil; 7mL of blood was used to obtain a complete blood cell count (CBC) and the pro ile of the serum biochemistry. Moreover, 5mL of urine were collected for analysis. There was no difference in values for male and female animals, as for the CBC and serum biochemistry. Some hematological and serum biochemical parameters were in luenced by age, showing signi icant differences. Urinalysis results were just demonstrated in a descriptive form. The studied values were, RBC 4.35+0.73 x 10 /μL, WBC 7.72+3.66 x 10 /μL (predominance of segmented neutrophils), platelets 227.06+111.58 x 10 /μL, urea 43.06+14.28mg/dL and creatinine 1.03+0.24mg/dL. Hematological, serum biochemistry and urinary values obtained in this study can be used as physiological values of the captive Crab-eating Fox. It is possible to conclude that wild species need their own reference values, differentiating animals in captivity from free-ranging animals.
