👉 A trilobite is a type of marine invertebrate that has four lobes, which are attached to the body and serve as arms or appendages. These creatures are found in various environments such as saltwater and freshwater habitats. They have a long, slender body with a smooth, shiny surface and a tough, muscular shell covering their bodies. Trilobites play an important role in marine ecosystems by providing food for other organisms and helping to control the population of certain species.
