What is the author's style in The Fish by Marianne Moore?

The poem looks like it does on the page because of its syllabic structure. However, the concrete visual imagery in the poem constructs another "look" in readers' imaginations. Images are concrete when they refer to one of the senses. Imagism was a movement popular at the beginning of the twentieth century. Imagists rejected sentimentalism and believed that poetry should create new rhythms, use precise, clear images, and address any subject the poet desired. Other imagists writing during Moore's time include Amy Lowell, William Carlos Williams, H. D. (Hilda Doolittle), and Ezra Pound.
