radula
The ______ is a rasping, protrusible, tongue-like organ that is found in almost all molluscs except bivalves.
The radula is a feeding apparatus found in most mollusks, including snails, slugs, and some clams. It is a ribbon-like structure with rows of small, chitinous teeth that are used to scrape and shred food.
The radula is located within the mouth and is extended outwards to capture and manipulate food. It works by rasping or scraping food particles from surfaces and then moving them towards the digestive tract. The teeth of the radula are replaced continually throughout the mollusk’s lifetime.
The radula is an important adaptation for mollusks, allowing them to feed on a wide range of food sources, from marine algae to decaying organic matter. However, the structure and function of the radula varies across different mollusk groups, reflecting the diversity of feeding strategies and ecological adaptations within this group of animals.
