If you want any more idea's for the setting, the national symbol of Singapore on which I presume Selimpore is loosely based is the Merlion, upper half lion, lower half fish. So...

Though rarely seen (at least by those who live to tell the tale) these aquatic rakasta are known as the Saviours of Selimpore, protecting the independence of the island state by harassing the shipping of those who would threaten it's waters. Though known to be extravagantly coloured in golds, greens, blues and purples, little else is known about this elusive people despite the best efforts of Myoshiman spies. Adept at sinking ships from below, they are known to use hardened coral tools when necessary and that favoured warriors wield special Coral Claws.
Occasional rumours speak of ogre sized warriors who accompany large (30+) parties of Merkasta, though some believe these to be another allied species of Mer-Lion types.
