What exactly the Whale Shark Museum is all about, we do not know at this point!

Whale sharks have been present in Talisayan’s waters since at least the 1950s and hunting them for their fins was a source of income for some coastal communities until the Bureau of Fisheries and Aquatic Resources banned the practice in 1998. (Source)

There have been some observations of Whale Sharks and Mega-mouth Sharks in Misamis Oriental water.

WHALE SHARK (Rhincodon typus)
The whale shark is the largest fish. One of the largest whale sharks recorded, reportedly from the Taiwanese fishery in 1987, measured 20 m and 34 tons in mass (Chen et al., 1997) .

Most of the whale sharks found in the Philippines have lengths of five to seven meters, meaning they are juveniles as sexually mature individuals are eight to nine meters long, at around 20 to 25 years of age. The smallest whale shark in the world was found in Bicol waters at 0.46m in length. The whale shark has a distinguishable checkerboard and spots pattern on its body except in the ventral side. Another distinguishing feature of the whale shark would be its terminally located mouth. They are found throughout the Philippines with a number of feeding aggregations near the coast, such as the Ticao/Burias Pass, Bohol/Mindanao Sea, and Puerto Princesa Bay. These feeding aggregation sites are the location of a lucrative whale shark interaction tourism enterprise. (Source)

MEGAMOUTH SHARK (Megachasma pelagios)
Reaching a length of more than 5m, the megamouth shark is the world’s third largest fish next to the whale shark and basking shark.

The species is wide-ranging and is recorded to occur in depths between 15 to 150m. The megamouth shark is one of the rarest sharks in the world with only 63 records since the first specimen was recovered in 1976. Fourteen of those incidences were reported from the Philippines as strandings or as bycatch. (Source)

Whale Sharks in Iligan Bay
“So, Iligan Bay is also along the whale sharks’ migration path. This was confirmed on Feb. 4, 1999 as a 15-meter whale shark, Rhincodon typus, was trapped in a fishpen of Eduardo Gaid, and released unharmed by noon in Barangay Maputi, here, about 60 kilometers from Cagayan de Oro and 28 kilometers away from Iligan City.”
