Some of them, such as insects, (to have) got an exoskeleton; others, like the jellyfish,(to have) got a fluid-filled, hydrostatic skeleton. There (to be) several types of invertebrates: porifera, cnidarians, annelids, molluscs, arthropods and echinoderms What animals are invertebrates? Among the simplest invertebrates (to be) the porifera, commonly called sponges. These(to be) asymmetrical aquatic organisms with no distinct tissues or organs. Their bodies(to be) filled with holes through which water (to circulate) continuously. This water flow(to provide) food and oxygen. Cnidarians (to be) the simplest form of life with tissue organisation. This group is diverse in form, but they all (to have) got radial symmetry. The ends of the structures(to have) got tentacles with stinging cells (to use) to capture food. Cnidarians(to have) a single opening that (to act) as both mouth and anus. Cnidarians can(to have)two basic body shapes: the polypoid shape of corals and anemones, which is(to fix) to a substrate or anchored to a colony, and the medusoid shape of free swimmers, like the jellyfish. Annelids(to have)got a complex organ system, including well-developed reproductive and digestive organs, and an open circulatory system. Their bodies (to be divided)into similar external and internal segments called metameres. These creatures (to have) got bilateral symmetry. Annelids (to include) earthworms, leeches and marine worms (to know) as polychaetes. Molluscs (to be) characterised by a soft body, an internal or external shell and a muscular foot. Molluscs (to be) divided into three groups: gastropods, such as snails, bivalves such as clams, and cephalopods such as the octopus. Echinoderms (to be) aquatic animals which(to have)got a hard spiny covering, a calcite skeleton and radial symmetry. Echinoderms (to have)got a watervascular system, and a set of water-filled canals or tube feet which they (to use) for locomotion, protection and to obtain food. A starfish is an example of an echinoderm. Arthropods (to be) the most numerous and varied of all animals. They (to have) got an exoskeleton and jointed appendages. Their bodies(to be) divided into segments. They (to have) got differentiated sensory organs. Insects, arachnids, crustaceans and miriapods(to be)different groups of arthropods
