Segmented coelomates with a notecord; possesses a dorsal nerve cord, pharyngeal slits, and a tail at some stage of life; In vertebraes, the notecord is replaced during the development by the spinal column.

Most successful of all animal phyla ;chitinous exoskeleton covering segmented bodies with paired, jointed appendages; many insect groups have wings.

Soft-bodied coelmates whose bodies are divided into three parts: head-foot, visceral mass, and mantle; many have shells; almost all possesses a unique rasping tongue , called a radula; 35,000 species are terrestrial.

Segmented coelmates with a notecord; possesses a dorsal nerve cord, pharyngeal slits, and a tail at some stage of life; in vertebrates, the notechord is replaced during development by the spinal column; 20,000 species are terrestrial.

Solid, unsegmented, bilaterally symmetrical worms; no body cavity; digestive cavity, if present., has only one opening.

Pseudocoelomate, unsegmented, bilaterally symmetrical worms; tubular digestive tract passing from mouth to anus; tiny; without cilia; live in great numbers in soil and aquatic sediments; some are important animal parasites.

Coelomate, serially segmetned, bilaterally symmetrical worms; complete digestive tract; most have bristles called setae on each segment that anchr them during crawling.

Soft, genatalious, radially symmetrical bodies whose digestive cavity has a single opening; possess tentacles armed with stinging cells called cnidocytes that shoot sharp harpoons called nematocysts; almost entirely marine.

Deuterostomes with radially symmetrical adult bodies; endoskeleton of calcium plates; five-part body plan and unique water-vascular system with tube feet; able to regenerate lost body parts; marine.

Assymmetrical bodies without distinct tissues or organs; saclike body consists of two layers breached by many pores; internal cavity lined with food-filtering cells called choanocytes; most are marine.
