Philippines — Thresher Shark Liveaboard

  • Atlantis Dumaguete (map)


Jul. 18th - 30th, 2019



Dumaguete & Malapascua

Malapascua is the only place in the world where you can dive with the magnificent thresher sharks every day

Monad Shoal near Malapascua is a sunken island at 16-32m whose sides drop off to 230m. The thresher sharks live and hunt in this deep water for most of the day, but in the early morning, before it gets too light, they come up to the Shoal, attracted by its cleaning stations. Here they have a symbiotic (mutually beneficial) relationship with the small fish called cleaning wrasse which eat dead skin and bacteria from the shark's body, its gills, and even inside its mouth.

They eat squid and schooling fish such as herring and mackerel and they use their tails to "corral" the fish into denser schools. The tail may also be used to stun the fish. They will sometimes "breach" and can jump completely out of the water.

The sharks are not dangerous to humans and will swim over the side of the shoal if startled. Threshers like to circle, sometimes in twos and threes, so if we see a shark as it is swimming away, it is likely the shark(s) will soon come back into view. On our dives, we move slowly, and if we see a shark, we stop and wait. If we stay still and make no sudden movements, sometimes the sharks can come so close you could almost touch them.


Thresher Shark Malapascua Live Aboard with two days at the Dumaguete Resort to see all the exotic critters in the video above.  We will have two days at the Dumaguete Resort and then 10 days on the Azores Liveaboard as we dive islands on the way to see the thresher sharks in Malapascua.
