Some species concentrated on the trunk and branches of trees, some on slender boughs, others searched beneath the leaves. By acting together in this way they probably increased foraging efficiency as each species could catch others' escaped prey. They were also safer from attack by predators, as the group as a whole was more likely to spot approaching danger.

269:. Around 100 kilometres (62 mi) of cave passages within the massif have been mapped. La Grotte d'Andrafiabe, one of the most accessible caves, comprises at least 8.035 kilometres (4.993 mi) of horizontal passages. Indeed, the Massif contains the longest cave systems in Madagascar, and probably in the whole of Africa.

During the 1986 expedition, Phil
