Brachiopods phylum.
This is a small phylum, about 12 species known. In most modern classification schemes phoronids are thought to be the closest living taxa to the brachiopods. There are four species of phoronid recorded from British Columbia. Phylum Brachiopoda: Brachiopods or Lamp shells are a group that is best known from fossils.
Brachiopods are marine invertebrates, meaning they have no backbone, and are one of the few animal groups that live only in the ocean.

Brachiopods and mollusks are in different phyla (large divisions of life) because they have different body symmetries and internal structures. Brachiopods are a distinct phylum of organisms, containing many classes, orders, families, genera, and species. Clams are in the class Bivalvia, which is in the phylum Mollusca.
