Sea Serpent, Yellow Belly

This poorly described and infrequently encountered creature is shaped like a tadpole up to 100' long, with a huge flat head that imperceptibly merges into its flat body. Its tail is extremely long and tapering. The Yellow belly is a very striking shade of yellow in color, with a black stripe all along its spine and black transverse bands on its sides. It has only been reported in tropical waters. Because its description is so vague, there is, as yet, no way to make even an educated guess about what kind of animal it is (if it exists at all). Use the statistics of common whales with maximum hit dice, doing damage only with a bite that does 3d4x5 points of damage.
