Phylum MolluscaBryozoa Characteristics
What are some examples of the phylum Arthropoda? How are barnacles different from members of the phylum Mollusca? Do all members of the phylum Mollusca have shells? Which class in the phylum Mollusca has the greatest diversity? What are characteristics of cnidarians?
Being such a diverse group, invertebrates are classified based on a number of characteristics including morphology/structure, symmetry and life cycle, etc. Whereas some of the organisms have three body layers, others (primitive invertebrates) only have two body layers. Examples of invertebrate animals...
The Mollusca phylum is divided into several classes including bivalves, scaphopods, gastropods, cephalopods and more. These classes have significant differences from each other while still maintaining common characteristics. For example, both clams and octopi possess a mantle, mantle cavity, and a ...
Phylum Mollusca “soft body” Basic Characteristics Bilateral Symmetry Open Circulatory System Herbivores, Carnivores, Filter-feeders, Scavengers, or Parasites Aquatic and Terrestrial Movement: Motile (very diverse ways, even jet propulsion!) Reproduction: Sexual (often external fertilization) No Asexual rep...
Mollusca are a phylum of Animalia, grouped together due to all members being invertebrates with distinct areas for their head and feet. The kingdom Archaea has only two phylums, Euryarchaeota and Crenarchaeota which are divided based on rNA sequences and their DNA polymerase. In the kingdom of...
5 classes of Mollusca: Cephalopoda characteristics of which Class?-shell reduced or absent - head well developed with eyes and radula; foot modified into a siphon -ganglia centralized to form a brain -separate sexes trocophore first larval stage of molluscs ...
The best known animal phyla are the Mollusca, Porifera, Cnidaria, Platyhelminthes, Nematoda, Annelida, Arthropoda, Echinodermata, and Chordata, the phylum to which humans belong, along with all other vertebrate species, as well as some invertebrates such as the lamprey. Although there are approximat...

Hemichordata- This phylum contains worm-like animals that share some characteristics with chordates, including having nerve cords. Mollusca-This diverse phylum includes an estimated 50,000 to 200,000 species of snails, sea slugs, octopuses, squids, and bivalves such as clams, mussels, and oysters...
