Euchlanis is a genus of rotifers belonging to the family Euchlanidae.
Sometimes alternatively referred to as wheel animalcules, rotifers feature a characteristic circular arrangement of cilia at their front ends that is reminiscent of a turning wheel when they are in motion. The genus has a cosmopolitan distribution.
Description
Rotifers have a characteristic circular arrangement of cilia at their front ends. These cilia are used to bring food particles, including bacteria, debris and small protozoans, towards the mouth. A mastax, a jaw-like structure, grinds the food as it enters the stomach. Excretory structures known as flame cells create a current that drains them into the intestines or the bladder. They have transparent bodies and two strong structures that are used for swimming. They are sheathed in a glassy shell secreted by their outer skin.
