What we saw was a Short-Finned Pilot Whale (Globicephala Macrorhynchus). It has a big almost round head, a falcate dorsal fin with wide base located closer to their head. The male grows to be 7m long, while the female grows to be 6m long.
The great thing about dolphin watching in Palawan is that they offer 100% money back guarantee if you don't see any dolphins during your tour. Which only means that they are very confident that you will truly see these dolphins. But I don't think the 100% money back guarantee applies to seeing the whale during your tour. So seeing one is truly a big bonus. And definitely a wonderous experience.
Some of my personal tips acquired during our dolphin watching expedition can be seen in my first post of Puerto Princesa Palawan. To those who plan to enjoy this extraordinary experience, I do hope you will love it as much as we did!
