Marine Life
Bali sits on the edge of the Coral Triangle, which is why one dive can swing from oceanic sunfish and reef mantas to thumbnail-sized nudibranchs on a black-sand slope. Knowing what shows up where — and when — is half the battle.

No guarantees, just realistic expectations grounded in how these species actually move.
