Monad Shoal dive site is most famous for being the only dive site in the world where threshers sharks can be seen on most days. It is found on Malapascua Island in the Cebu area and is a well known dive in the area. Seeing the Thresher Sharks is quite remarkable as most of the time, these sharks live at around 350 meters and so it is rare to see these large fish. They can grow up to six meters and are have a very distinctive shape, with a long and angled tail that is used to smack and stun fish during hunting.

The site is a cleaning site for these thresher sharks, and they come here to be cleaned of parasites by other smaller fish. The site also attracts rays for the same reason and so divers can see devil rays and eagle rays as well.

Manta rays are also frequent visitors and they are commonly sighted by divers making this a very popular dive site. Given its depth, this dive site can only be completed by experienced divers. It is advisable to complete the dive with mixed air to get a longer bottom time.

The dive site is actually an underwater island at a depth of around 28 meters, with a diameter of around 1.5 km. There is a reef at 14 meters, which has some great coral, but the real action happens on this island at around 28 meters. Along with the larger pelagic fish, divers can also spend time looking at the fusiliers and cleaner wrasses that are waiting to do clean the other fish.
