👉 Trematocoris, also known as the brachyura, is a class of protists that includes a wide range of organisms from aquatic plants and algae to fish and crustaceans. These creatures are characterized by their unique cell structure called a trichium, which is composed of multiple layers of cells arranged in a spiral pattern. Trematocoris is often associated with the formation of the ocean floor due to its ability to grow rapidly in nutrient-rich environments.
