Study Finds Some Female Frogs May Consume Males After Breeding in Acts of 'Sexual Cannibalism'

Cannibalism in Frog
This unprecedented behaviour, where females prey on males,
Cannibalism is well known among amphibians. But usually, it is the youngest frogs, toads, or salamanders that end up as dinner. The tadpoles of various species eat smaller tadpoles, for example, to get ahead in life. In some cases, this happens regularly between siblings. In others, adults sometimes cannibalize eggs or larvae — researchers recently discovered that hellbender fathers may eat their young when faced with suboptimal water conditions.
Many species of frogs are sexually dimorphic. The adult female frogs are much larger in size than their male .females can exploit their male counterparts, not only as breeding partners, but potentially as prey.
What is cannibalism among amphibians?
Active forms of cannibalism that involve predation of live conspecifics occur widely among amphibians, most notably by tadpoles that feed on each other and adults that feed on juveniles.
Do bullfrogs cannibalize?
If they determine the potential prey item will fit into their mouths, they will try to eat it. This means that Bullfrogs can be cannibals, eating their own young. This is an important component of Bullfrog population dynamics: large adult Bullfrogs help to control populations by eating younger Bullfrogs.
