The correlation between characteristics of growth and energy metabolism during the larval stage of development of the Spanish ribbed newt (Pleurodeles waltl) has been studied. During this period, its body mass is found to increase 140 times and the oxygen consumption rate, 77 times. The highest rate of specific body mass increase and oxygen consumption rate are noted in the early larval stage. Later, these characteristics decrease except for a brief period before completion of metamorphosis when the rate specific body mass increase rises. Comparison of the studied characteristics allows us to note a similar pattern in changes of the specific growth rate and the oxygen consumption rate during the premetamorphic development of the Spanish ribbed newt.
