Among the wilds in its rainforest and mountainous areas lives the Philippine tarsier.
The economy of Kiamba is largely based on agriculture with vast ricefields surrounding the municipality. Aqua-culture is the second biggest income earner, notably the culture of milkfish and shrimps (locally called "sugpo" or "lukon") for export. Also, coastal communities depend on deep-sea fishing as a primary livelihood.
Kiamba is politically subdivided into 19 barangays.
