Bilaterians are animals that have bilateral symmetry, meaning that they can be divided into equal left and right halves. All animals are bilaterians, with the exception of a few groups of invertebrates such as sponges and cnidarians. Coeloms are lined by the lining of the mesoderm, which is located on the inside of the coelom.Bilateral symmetry and cephalization; Sensory, feeding structures at one end; Reduced cross-sectional area; Good for burrowing, getting into protective crevices, insinuating into tissue spaces of organisms (parasitism) Large surface area/volume; Gas exchange, waste removal, nutrient uptake; Elongate digestive tract Mollusca is the second-largest phylum of invertebrate animals, after Arthropoda; members are known as molluscs or mollusks [a] ( / ˈmɒləsk / ).
