Determination of serum glucose, protein, cholesterol, urea, sodium, potassium and calcium were made in monthly sample of blood collected from male and female frogs and toads from tropical Western Ghats, India over a period of two years annual cycle. Serum glucose was significantly higher in frogs, whereas protein, cholesterol, urea, potassium and calcium concentration assumed higher in toads. However, sodium concentration did not alter throughout the study between the two species.Serum protein, cholesterol, potassium and calcium concentration were significantly higher during monsoon, whereas glucose was decreased. However, urea was rose to maximum during post monsoon period.
