Marine turtle species are an integral part of oceanic ecosystems throughout the world [1]. Green turtle is the largest of the hard shelled sea turtles and is the second largest (after Dermochelys) of the seven species. Green turtle is a circumglobal species found in tropical and sub-tropical waters [2,3]. The Coast of Oman Sea has some of the most important nesting sites for green sea turtles in the world. At present, there is limited information on the biomarkers of health status of the population of green turtle (C. mydas), in Oman sea.The purpose of the present study was: 1) to determine biochemical analytes in the blood of nesting green turtle in light of those previous studies on the northern coast of Oman sea, Chabahar, Iran. 2) to determine hematological values in the blood of nesting green turtle on the northern coast of Oman sea, Chabahar, Iran. 3) to evaluate and compare sodium heparin and lithium heparin as anticoagulants for measuring selected biochemical anal.
