👉 A multiciliated organ is an organism that has multiple specialized cells or tissues. These cells are interconnected and work together to perform specific functions in the body. The term "multiciliated" refers to the fact that these organs can have different sizes, shapes, and structures within them. For example, the eyes of a fish are multiciliated because they have two types of eyes (spherical and round), and the heart of an insect is multiciliated because it has many specialized cells.
