difference between phylum echinodermata and phylum arthropoda
Answers
Answer:The main difference between echinoderms and chordates is that the echinoderms have a mesodermal skeleton made up of calcite known as ossicles whereas chordates have an internal skeleton made up of bones and cartilages. Furthermore, echinoderms show radial symmetry while chordates show bilateral symmetry.
Explanation:The larval stages of echinoderms are always bilaterally symmetrical, like the one shown here, even though adults are radially symmetrical. ... Unlike mollusks, annelids, and arthropods, echinoderms are not protostomes. The species of the phylum Echinodermata and the phylum Chordata are all deuterostomes.
Answer:
Answer:The primary difference between arthropods and echinoderms is their covering. Arthropods have a tough, non-living outer shell called exoskeleton, which protect their soft bodies while echinoderms have living endoskeletons, which develop within the deeper skin or body tissues and act as their protective covering.
