They can mix together an array of other compounds, including invisible pheromones for mating, and others called lucibufagins (loosa-BOOF-ajins) that ward off predators like spiders and birds. Male Overload Khelifa observed that females have another diversionary tactic: They lay their eggs in dense vegetation, where it's harder for males to find them.
