If you happen upon a frog that appears dead, it’s worth being skeptical. Some frogs have the ability to play dead as a defense strategy against predators. Poison Dart Frogs can secrete toxic substances to discourage predators, but for other species, playing dead might be their only defense when running away isn’t an option.
Each frog species might demonstrate playing dead differently with the Vietnamese Mossy Frog curling up into a ball while the Leaf Litter Frogs from South America position themselves on their back with stretched-out legs and closed eyes. Scientists have observed Leaf Litter Frogs holding this position for two minutes at a time.
Although hibernating frogs may appear dead, there are ways to tell them apart. When the temperature drops, many frogs across various species hibernate to survive. They rely on external warmth to stay alive because they cannot regulate their body temperature, and this is in short supply during the winter months. When hibernating, their metabolism rate drops, allowing them to survive without eating for long periods, and the overall temperature of their body decreases. They also redirect blood flow from their lungs to their skin, where they can absorb all the oxygen they need through their pores.
Frogs playing dead will still be warm to the touch, while hibernating frogs will feel cold. Additionally, hibernating frogs protect their eyes by pulling them slightly into the head and covering them with a third eyelid while dead frogs may have closed eyes or unprotected ones. Another way of telling is by observing the skin on the frog’s belly, which turns red or pink, indicating increased blood flow.
For pet frogs living indoors, they shouldn’t have a reason to play dead as they are in a safe and protected environment. They also won’t hibernate as controlled temperatures are maintained, but if the temperature falls too low, they may slow down or appear dead. Pet owners should monitor the temperature in the enclosure and gradually increase it if their pet’s behavior is abnormal.
In conclusion, various species of frogs may play dead as a defense mechanism against predators. However, they will quickly return to normal once the danger has passed. Hibernating frogs may appear dead, but there are ways to tell them apart. Pet owners should ensure they maintain the recommended temperature for their pet frog’s species to prevent any issues. As always, seek professional medical help if your pet’s behavior is abnormal.
