Beyond the species list
A sense of place.
Panay is a roughly triangular island northwest of Negros and southeast of Mindoro. It contains the provinces of Aklan, Antique, Capiz and Iloilo. Guimaras lies just off its southeastern coast.
Landscape & habitats
The Central Panay Mountain Range forms a major axis through the island. Mount Madja-as in Antique illustrates its high mountain scenery, contrasting with the lower ground and coast around the island’s margins.

Islands, barriers & evolution
Zoogeography
A core island of the West Visayan region
Panay is a principal island of the Greater Negros–Panay complex. A comparative herpetofaunal study found strong similarities with Negros and Cebu, interpreting these patterns in the context of former Pleistocene connections.
The same work stressed that further taxonomy and field studies would change assessments of endemism. Panay’s fauna is therefore best read at two scales: its regional relationships and the individual habitats and localities where animals have actually been documented.
How to read the historical island groups
During Pleistocene glacial periods, lower sea levels exposed shallow seabeds and joined some present-day islands. Biogeographers call these reconstructed landmasses Pleistocene Aggregate Island Complexes (PAICs). Deep channels continued to separate others. This model helps explain regional similarities, but dispersal, older geology and habitat differences also shaped each fauna.
“Endemic” means restricted to a stated area; a Philippine endemic need not be confined to one island. The account above summarises published regional and local research. It does not add occurrences to the snake index below.
