Kataw

 The Kataw is one of the merfolk in Philippine mythology, particularly in Visayan folklore, where they are considered superior to other water and sea beings like the Sirena, Sireno, and Siyokoy. Kataws are believed to hold the highest rank as the rulers of the underwater kingdom known as Bantay Tubig.

Physically, the Kataw, along with the Sirena and Sireno, has a humanoid appearance, distinguishing them from the Siyokoy, who have more fish-like or creature-like features. Unlike the Sirena, most Kataws have feet rather than tails, yet they retain marine traits, such as gills on their bodies and fins on their arms. Known for their deceptive nature, Kataws can disguise themselves as fishermen in need of assistance, but when approached, they are said to pull mortals into the depths of the ocean.

According to folklore, Kataws possess the powerful ability to manipulate water and related elements, controlling tides, waves, pressure, and even creating bubbles. They can also transform water into ice. In some Visayan tales, the Kataw appears more frightening, blending both human and fish-like features in a way that emphasizes their fearsome and otherworldly nature
