Liam has gone to a store to buy posters. He asks the shopkeeper to give him a poster, which has bivalves, octopuses, squid, and sea snails on it. To which phylum does the poster belong? A. Bryozoa B. Hemichordata C. Ctenophora D. Rotifera E. Molluska

The phylum to which squid octopuses, snails and bivalves belong -which must have Liam's poster- is molluska (Option E).

Explanation:

Molluscs are invertebrate organisms, whose body is soft and may be covered by shells or carapace. The phyllum mollusca covers a wide variety of species, about 100,000, of which squid, octopus, bivalves and snails are part.

Among its characteristics is that they are celomed organisms, of bilateral symmetry and formed from three embryonic leaves. A common feature is the existence of a structure provided with multiple chitinous teeth that serves them to feed, called radula.
