1. 08

   Direct development in robber frogs is an adaptation that eliminates dependence on standing water, allowing colonization of dry and seasonally arid habitats unavailable to most amphibians.

   Nocturnal hunting behavior allows robber frogs to forage for small arthropods at night when fewer predators are active, giving them competitive advantage in dense neotropical forests.
