Fish Eggs Survive Trip Through Bird Innards
Scientists have long wondered how isolated bodies of water can suddenly become populated by fish. A miracle? Science has an answer. It turns out it’s all thanks to the resilience of fish eggs. For these eggs, getting gobbled up by waterfowls and ducks does not mark their end.
