flatbodied
Flatbodied refers to a body shape characterized by a dorsoventrally flattened form, meaning it is compressed from top to bottom. This anatomical feature is common in various animal groups, particularly those that inhabit environments where a low profile is advantageous. For example, many aquatic and terrestrial invertebrates, such as certain types of worms, crustaceans, and insects, exhibit a flat body. This shape can aid in several ways, including navigating narrow crevices, moving along surfaces, or increasing surface area for respiration or absorption. In some cases, a flat body can also help in camouflage, allowing the organism to blend more effectively with its surroundings by appearing less conspicuous. Among vertebrates, some fish, like rays and flounder, have evolved extreme flat bodies to live on the seabed. This adaptation allows them to lie in wait for prey or to bury themselves in sediment. The specific evolutionary pressures leading to a flat body vary depending on the species and its ecological niche.
