Situated off the east coast of Maricaban Island are two smaller ones worthy of mention - Bonito and Malajibomanoc (meaning chicken feather in Tagalog). They are both marine sanctuaries that have coral heads on sandy slopes from 6-24m. Currents can be strong.
Malajibomanoc has hot springs at 20m. Corals are abundant as are barrel sponges and crinoids. You can encounter parrotfish, groupers, batfish, trumpetfish, cornetfish, moray eels, anthras and pufferfish. Blacktip reef sharks frequent the area as well.
When there's a current, shoals of jacks, snappers and fusiliers can be seen. In amongst the sandy areas, sea urchins, sea cucumbers, stingrays and moray eels can be found.
