Create an enchanting underwater scene featuring the Maranthe, a sleek, amphibious creature with two finned legs, two long, webbed arms, and a flowing tail fin. Its deep indigo and sea-green scales shimmer with an iridescent glow, and its large, bioluminescent eyes radiate a soft light adapted for dark ocean depths. Frilled gills extend from the back of its head, gently undulating as it glides through bioluminescent coral forests. Swirling, glowing patterns on its body pulse like ocean currents, blending with the surrounding light, creating a mesmerizing, otherworldly atmosphere.
