Beyond the species list
A sense of place.
Tablas is the largest island in Romblon province. It lies east of southern Mindoro, with Romblon Island close to its northeastern end. Odiongan is a major settlement on its western coast.
Landscape & habitats
A wooded central hill range runs along the island. Mount Payaopao rises at its northeastern end and is the highest point on Tablas. The photograph places this relief within the surrounding landscape.

Islands, barriers & evolution
Zoogeography
Romblon–Tablas connectivity, separated from Sibuyan
A shallow channel between Tablas and Romblon makes a former low-sea-level connection plausible in published reconstructions. Sibuyan, by contrast, remained separated by much deeper water.
This distinction explains why the Romblon provincial grouping should be unpacked when studying animals. Herpetofaunal inventories reveal restricted distributions within the group; shared historical access need not result in identical present-day assemblages.
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.
