Ah een meelow

The Ah Een Meelow is an alleged sea serpent inhabiting the waters of New Ireland, Papua New Guinea, especially in Ramat Bay on the central east side. Little is known about them besides their appearance. It is 50 feet long, with greyish-green or blue bands around its body, 10 feet apart. They are also described as having a frill on their back, with a two-foot-long vertical, segmented tail. They move in a vertical undulating motion and are often seen near the coast. 

The only source of this cryptid is Paul Cropper and Malcolm Smith’s unpublicized Australasian sea serpent reports, so there is very little information on this cryptid.
