Chapter 6: Phylum Brachiopoda. 6.1 Introduction. While recent brachiopods are a rather rare and insignificant group, their long fossil history shows that they were at times the most prominent animals in the seas.he phylum is quite important for biostratigraphy, paleoecology, and evolutionary studies because it shows a great variety of changes in form and function through time. Brachiopods appear near the beginning of the Cambrian, but did not become abundant until the Early Ordovician.
At the seashore animals will be from the Animal Kingdom in these phyla. 1  Phylum: Mollusks (Soft-bodied animals that sometimes have a hard shell. 2  Includes: snails, octopus, squid, clams, oysters, and mussels.).3  Phylum: Echinoderms (Often spiny animals, with several arms reaching out from the center of its body. Includes: starfish, sea cucumbers and sea urchins.). 2  Phylum: Arthropods, SubPhylum: Crustaceans. 3  Crabs, lobsters, shrimp, barnacles and many other animals belong to the phylum arthropods. 4  In fact, 75% of all animals belong to the phylum arthropoda (which also includes spiders and insects).
