ctenidium
Quick Summary
A ctenidium is the gill of a mollusk. These gills are typically comb- or feather-shaped and are located on the inner side of the mantle. Ctenidia are a key feature of mollusk anatomy, playing a crucial role in their respiratory system. In bivalves, for example, the ctenidia are modified for filter-feeding and gas exchange, with their structure varying depending on the species' lifestyle, from burrowing to free-swimming. Mollusks, as a phylum, are characterized by having lamellate gills, known as ctenidia.1234

molluskExternal features…pair of lamellate gills (ctenidia), a thick layer of glandular epithelium called mucus tracts or hypobranchial glands, and the outlets for the digestive, excretory, and reproductive systems. A loss of the ctenidia (along with the mucus tracts) is seen in scaphopods, advanced gastropods, septibranch bivalves, and solenogasters.

…brooding typically occurs within the ctenidia. There the fertilized eggs, well endowed with yolk, develop directly (without a larval stage), and the young are released as miniature adults. Although ctenidial incubation is most common, there are other patterns: egg capsules are produced by Turtonia minuta; a brood chamber is plastered…
