Clam symmetry
Clams possess bilateral symmetry across both shells, which contain several external features such as: the umbo, or beak; the tail, or posterior region of the …Alitta virens (Clam Worm) is a species of segmented worms in the family ragworms. They are associated with freshwater habitat. They are biodiffusors. They are omnivores. Individuals can grow to 300 mm. They rely on drag powered swimming to move around. EOL has data for 48 attributes, including: Body symmetry. bilaterally symmetric.Clams are filter feeders. Water and food particles are drawn in through one siphon to the gills where tiny, hair-like cilia move the water, and the food is caught in mucus on the gills. From there, the food-mucus mixture is transported along a groove to the palps (mouth flaps) which push it into the clam's mouth.
