Beyond the species list
A sense of place.
Catanduanes lies east of Camarines Sur, separated from the Bicol Peninsula by the Maqueda Channel. It forms the main island of a province that also includes smaller offshore islands and rocks.
Landscape & habitats
Binurong Point shows the island’s coastal character particularly well: green headlands, steep slopes and exposed rocky edges meet the sea. These coastal landforms provide a useful sense of place alongside the island’s broader inland terrain.

Islands, barriers & evolution
Zoogeography
The eastern margin of Greater Luzon
Catanduanes is included in the Greater Luzon Pleistocene island complex, together with Luzon, Polillo and Marinduque. This historical grouping connects its zoogeography to Luzon despite the sea that separates them today.
Research on Philippine forest birds shows why a shared island complex is only a starting point: populations can develop distinct histories within a region. The same question needs to be tested separately for each reptile lineage, using actual island records and evolutionary evidence.
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.
