Female Frogs May Eat Males After Breeding

In a study titled “Meal or Mate: Exploring the Evidence of Sexual Cannibalism Among Amphibians,” Dr. John Gould from the University of Newcastle shares startling observations from Kooragang Island, north of Sydney, Australia. This research, published in the Journal of Ecology and Evolution, sheds light on a rare and fascinating behavior among green and golden bell frogs.

During his fieldwork, Dr. Gould observed a female green and golden bell frog attempting to consume her male counterpart. Captured in photos and videos, this event revealed the female frog grabbing the male’s leg and pulling him towards her mouth. The male frog responded with a high-pitched screech before eventually escaping and hopping away.

Dr. Gould’s study not only documents this specific incident but also reports on female frogs preying on other frog species, such as marsh frogs. These observations have led to a new hypothesis that female frogs might be exploiting male suitors for either breeding or food, with the male’s call possibly determining his fate.

The University of Newcastle highlighted the significance of these findings, as amphibian cannibalism typically involves tadpoles or adults consuming juveniles. Dr. Gould’s research is the first to document adult green and golden bell frogs exhibiting cannibalistic behavior towards each other, prompting further investigation into this intriguing aspect of amphibian life.
