The recent exploration (Dec.7-8, 2015) to Casili Underwater Cave System in Brgy. Arpili- Balamban, gave the team the opportunity to video document a previously unobserved denizen of the deeper portion of the site. Captured on video is a yet-to-be described fish that was spotted at a depth of 32 meters and around 600 meters away from the cave entrance. Length of the specimen is approximately 5 inches long. The team was unable to secure a live sample for study.
Alex Santos, Jaime Lapac and Bernil Gastardo composed the team. For the successful 2-days of exploration, much appreciation and gratitude goes to the hearty support and kind cooperation of the local council and barangay tanods led by Barangay Captain, Hon. Rhodessa Paulin.
