Poison Frogs Make Their Babies Toxic, Too

1 post in this topic

Strawberry poison frogs (Oophaga pumilio) of Costa Rica give their newborn tadpoles a built-in weapon against predators: alkaloids.

The team already knew that strawberry poison frog mothers feed their babies unfertilized eggs. But their new research revealed the eggs are also spiked with alkaloids - the first time an animal has been found to pass on such chemical defenses to its offspring.
