Rotifers Feeding

A short sequence showing some feeding aspects of the rotifer Collotheca ornata, found in a pond. Rotifers are amazingly beautiful semi transparent microscopic animals. Rotifers are found throughout the world and are a common component of clean freshwater bodies, such as ponds and lakes. Found attached to plant material, rotifers feed by expanding a structure known as a corona, which is covered (in the species seen here) by numerous cilia (hair-like structures). These cilia beat to create water currents that sweep food (microscopic algae) into the mouth. The can be sessile (fixed to a substrate) as seen here or free swimming. These ones are female.There are over 500 species found in the United Kingdom. They take their name from the word Rota, meaning wheel, as many possess a corona that appears as a wheel like structure(s) covered in cilia. • • If you like what you see then please also check out my other work here: • http://www.sciencephoto.com/search?su...
