Phylum Mollusca: Station 6 This group includes snails, clams and squid, oysters and more. They have the most advanced nervous system of all invertebrates.

Arthropods: Arthropods constitute over 90% of the animal kingdom. ***First phylum to have joints*** The word Arthropod literally means jointed legs. ***First.

Cnidarians. Characteristics Cnidarian means Thistle Referring to the stinging cells (nematocysts) that all members possess All aquatic Radial symmetry.
