What endemic fauna on Christmas Island suffered catastrophic population crashes due to A. gracilipes predation?
Answer
Large, flightless crabs
The most notorious ecological catastrophe caused by the yellow crazy ant occurred on Christmas Island, where they fundamentally altered the ecosystem by preying upon native species. Specifically, the populations of large, flightless crabs, which were a crucial part of the island’s ecology, crashed dramatically. This occurred because the ants aggressively targeted the vulnerable young and eggs of these crabs, demonstrating their destructive predatory nature when populations explode.
