Monad Shoal, a natural cleaning station for fish located from the island ( – 30–35 minutes boat ride). The shoal is a rather unremarkable long rock stump at the edge of a drop and has a flattish top at a depth of . The site is best known as the only place in the world where thresher sharks can be seen regularly at and just before sunrise. They use the seamount as a cleaning station for bluestreak and moon cleaner wrasse to remove ectoparasites such as gnathiids from their skin and clean their gills and mouths. The shoal also attracts other pelagic fish such as devil rays and eagle rays. Manta rays and hammerheads are seasonal. Unfortunately most of the coral reefs of the shoal have been damaged by destructive fishing methods, as has happened all over the Philippines, and elsewhere. In June 2016 a ship ran aground on the shoal, damaging of the protected area.
