The objective was to determine the hematological values of the Tumbes crocodile (Crocodylus acutus), a species categorized as in critical endangered of extinction by the Peruvian Government. Blood samples were collected by puncture of the venous sinus located in the postoccipital cervical region of male individuals separated into two age groups (15 juveniles and 15 sub-adult individuals) apparently healthy from the Tuna Carranza Aquaculture Center, Puerto Pizarro in Tumbes, Peru. After collecting the blood in tubes with lithium heparin, hemogram smears were made and microcapillaries were filled for the determination of hematocrit. The samples were sent and processed in the Laboratory of Clinical Pathology of the Faculty of Veterinary Medicine and Zootechnics of the Universidad Peruana Cayetano Heredia. The average values found were: 23.56% ± 3.23 of hematocrit, 8.48 g/dL ± 2.13 of hemoglobine, 0.988 106/µL ± 4.54 of red blood cells y 5.90 ± 4.27 103/µL of white blood cells: 2.68 103/µL ± 1.51 of heterophils, 1.58 103/µL ± 1.4 of lymphocytes, , 2.35 103/µL ± 2.4 of eosinophils, 1.45 103/µL ± 1.71 of basophils y 0.50 103/µL ± 0.85 of monocytes. No statistically significant differences were observed between age groups.
