How much blood is there in a frog in liters?

The blood volume in a frog typically ranges from about 3 to 4 percent of its body weight. For an average frog weighing around 100 grams, this translates to approximately 3 to 4 milliliters of blood, which is equivalent to 0.003 to 0.004 liters. Different species and sizes of frogs may have slightly varying blood volumes.
