Can't live, the nose that falls off the razor clam is a crystal rod.

Crystalline style also known as crystal column, crystal needle. For mollusks in the digestive tube of translucent gelatin-like rods. Containing a large number of digestive enzymes, the main donor of digestive enzymes.

There are many species in the phylum Valvularia and Gastropoda that are widely distributed, but the most notable is the shellfish that ingests zooplankton. It is found in the bursa of the crystal rod, the anterior end of which extends into the stomach and contacts the gastricshield of the stomach wall. In the living body, it rotates and grinds against the gastricshield, and the enzymes contained therein are slowly released into the digestive fluid.

Basic structure

In the toothless mussel, there is a transverse slit below the anterior closure muscle of the mouth. On each side of the mouth is a pair of triangular labial plates, densely ciliated, with sensory and feeding functions. Behind the mouth is a short and wide esophagus, which is connected to an enlarged stomach, which is surrounded by a pair of livers that can secrete amylase and sucrase, and has a duct into the stomach.

The crystal rod may be stored food, mussels in the lack of food conditions, 24 hours after the crystal rod that is disappeared, re-feeding, a few days after the crystal rod to restore the existence. Mussels feed on organic matter particles, rotifers, flagellates, algae, and small crustaceans.
