Big frogs usually live more. It is because they acquire food more easily than small ones. Also, larger ones are less dominated by other species. Moreover, the habitat of the frog supporting less competition and more food ensures a longer lifespan than the one stressed out under competition.
Predators are one of the most highlighted limiting factors in determining a frog’s lifespan. Predator is an immediate crisis leading to death or severely injured in most cases. If you are thinking frogs always succumb to the big creatures. Well, you might be wrong. They have multiple amazing defense systems like releasing toxins, attacking, etc. These defense mechanisms help them in almost 70% of the predator attack.
Among the lack of food and presence of a predator, the latter one still remain significant. Frogs can survive even in a drought if they flee from their predators.
Climate also affects a frog’s lifespan. If the climate is humid, frogs tend to live healthier. In the uncertain, dry, or hot weather, frog’s skin gets parched. You know frogs breathe through their skin. So, if it is not functioning correctly, frog’s do not receive enough oxygen, which results in ultimate death.
You might be surprised to know that even the latitude has a huge difference in the lifespan of the frog. For example, Common frogs from Europe have a lesser lifespan than those from the subarctic region.
Gender also seems to be a factor affecting the lifespan of the frog. Female frogs live more than male ones. The most important reason behind the greater lifespan of the frogs is that females have better defense mechanisms and live in long hibernations. Well, here you go with nature supporting feminism (chuckles).
