What are some phylum mollusca charateristics?

Answer 1

Characteristics include:

• Mantle
• Muscular Foot (in cephalopods this has branched out to form tentacles and arms)
• Radula - a chainsaw like feeding tongue (secondarily lost in some species such as the bivalves and some cephalopods)
• Calcium Carbonate Shell (secondarily lost in some cephalopods and some gastropods)
• Open Circulatory System

Answer 2

Mollusca is a phylum of invertebrates that typically have a soft body covered by a hard shell. They possess a muscular foot for movement, a visceral mass containing internal organs, and a mantle that secretes the shell. Most mollusks also have a radula, a rasping organ used for feeding.

Answer 3

All mollusks share three defining features. Most notably, they share the feature of a muscular foot, many of which use this to move. They also have a mantel and a radula.
