What is labial palps?
labial palp 1. In some Mollusca, one of a pair of flap-like folds at the end of each tentacle by which food is transported to the mouth. 2. One of the pair of jointed, sensory structures carried on the labium of the mouth of an insect. They articulate with the part of the labium known as the prementum.
What is the function of labial palps in cockroach?
These structures are homologous to the lacinia and galea of maxillae. The labial palps borne on the sides of labium are the counterparts of maxillary palps. Like the maxillary palps, the labial palps aid sensory function in eating.
What is Palp in cockroach?
The maxillary palp has a long micro-furrow near the ventral edge of the medial surface of the fifth segment, which has a high population density of 73,700 sensilla/sq. mm2. This groove-and-slit sensillum is a new sensillum described for the first time in insects, and we designate it as GAS sensillum.
What is the function of palps?

How does food move in a bivalve to labial palps?
The clam has a pair of very large gills, and the surface of the gills is covered with cilia. The cilia beat in a coordinated fashion, and the movement of the cilia cause water to move into and through the clam. The cilia are also responsible for transporting the trapped food to flap-like structures called labial palps.
Why is the clam called a filter feeder?
Clams are known as filter feeders because of the way they eat their food. Since they have no heads or biting mouthparts, they have to feed in an unusual way. They pull water — which also contains food particles — in through one of their syphons and into their gills.

Are all clams filter feeders?
The class has 30,000 species, including scallops, clams, oysters and mussels. Most bivalves are filter feeders (although some have taken up scavenging and predation), extracting organic matter from the sea in which they live. Nephridia, the shellfish version of kidneys, remove the waste material.
What is the best type of water for oysters to live in?
