The Papyrus Sea-otter is a ribald poetic form intended to praise rivers, originating in The Manageable Silt-Loam. The rules of the form are applied by poets to produce individual poems which can be recited. The poem is a single quatrain. Use of internal rhyme and alliteration is characteristic of the form. The second line of the quatrain reverses the word order of the first line. The first line has four feet with a syllable weight pattern of short-long (quantitative iambic tetrameter). The second line has three feet with a syllable weight pattern of short-long (quantitative iambic trimeter). The third line has eight feet with a syllable weight pattern of short-long (quantitative iambic octameter). The fourth line has five feet with a syllable weight pattern of short-long (quantitative iambic pentameter). The rhyme scheme of the poem is ABAA. The rhyme at the end of the second line doesn't need to match perfectly.
