What are two types of bivalves?
Examples of Bivalves
- Clams are mollusks found in both freshwater and saltwater environments.
- Oysters are a type of saltwater clam, and some varieties produce pearls.
- Mussels, like clams, are mollusks that can live in either freshwater or saltwater.
- Scallops are perhaps best known for their use as food.
Are mussels Lamellibranchs?
n. 1. any mollusk, as the oyster or mussel, of the class Bivalvia, having hinged lateral shells, a soft body enclosed by a mantle, sheetlike gills, and often a retractile foot.
How do you feed bivalves?
Like fish, bivalve mollusks breathe through their gills. As filter feeders, bivalves gather food through their gills. Some bivalves have a pointed, retractable “foot” that protrudes from the shell and digs into the surrounding sediment, effectively enabling the creature to move or burrow.
Which of the following is a characteristic of class bivalvia?
Presence of a coiled shell.
Is bivalvia a class?
Clams, mussels, oysters, and scallops are members to the class Bivalvia (or Pelecypodia). Bivalves have two shells, connected by a flexible ligament, which encase and shield the soft vulnerable parts of the creature.
Are scallops a bivalve?
Bivalve mollusks (e.g., clams, oysters, mussels, scallops) have an external covering that is a two-part hinged shell that contains a soft-bodied invertebrate. Like fish, bivalve mollusks breathe through their gills. As filter feeders, bivalves gather food through their gills.
Are bivalves herbivores?
Bivalves are among the few marine herbivores that humans eat in large amounts. Herbivores are animals that eat plants on land, like grass and leaves, or their marine equivalent, the microscope algae which are known as phytoplankton.

How are brachiopods and bivalves alike and different?
Brachiopods are shelled marine organisms that superficially resembled bivalves in that they are of similar size and have a hinged shell in two parts. However, brachiopods evolved from a very different ancestral line, and the resemblance to bivalves only arose because of a similar lifestyle.
Where are the neurons located in the lamellibranch?
Fine-structure of the neurons in the mid-dorsal lobes of the visceral ganglion of the Lamellibranch mollusc Scrobicularia plana (da Costa). Lamellibranch bivalves, such as golden mussel and zebra mussel, are extremely efficient in filter-feeding (Sylvester et al.
