invertebrate phylum that includes animals such as jellyfish and corals that are characterized by radial symmetry, tissues, and a stinger called a nematocyst

internal skeleton that provides support and protection

animal that obtains organic matter for nutrition by filtering particles out of water

medusa (plural, medusae)

basic body plan in cnidarians such as jellyfish that is bell-shaped and typically motile

phylum of invertebrates called roundworms, which have a pseudocoelom and complete digestive system

invertebrate phylum of flatworms that are characterized by a flat body because they lack a coelom or pseudocoelom

basic body plan in cnidarians such as jellyfish that is tubular in shape and typically sessile

invertebrate phylum of sponges, which have a non-bony endoskeleton and are sessile as adults

of or relating to an animal that is unable to move from place to place

invertebrate phylum of segmented worms such as earthworms

animal that obtains organic matter for nutrition by eating soil or the sediments at the bottom of a body of water

organs in aquatic organisms composed of thin filaments that absorb oxygen from water

muscular organ in the chest that that pumps blood through blood vessels when it contracts

layer of tissue that lies between the shell and body of a mollusk and forms a cavity, called the mantle cavity, that pumps water for filter feeding

phylum of invertebrates that are generally characterized by a hard outer shell, a mantle, and a feeding organ called a radula

regrowing of tissues, organs, or limbs that have been lost or damaged

invertebrate in the phylum Arthropoda, characterized by a segmented body, hard exoskeleton, and jointed appendages

process in which a larva undergoes a major transformation to change into the adult form, which occurs in amphibians, arthropods, and other invertebrates

process in which an animal sheds and replaces the outer covering of the body, such as the exoskeleton in arthropods

life cycle stage of many insects that occurs between the larval and adult stages and during which the insect is immobile, may be encased within a cocoon and changes into the adult form

arthropod, which is now extinct and known only from numerous fossils

consists of all animals with a notochord, dorsal hollow nerve cord, post-anal tail, and pharyngeal slits during at least some stage of their life

invertebrates such as sea stars and sand dollars that are characterized by a spiny endoskeleton, radial symmetry as adults, and a water vascular system

members of the subphylum Cephalochordata

members of the subphylum Urochordata are tunicates (also called sea squirts)
