Annuli is a ring shaped bony part of the fish which is used to determine the age.

Annuli are a type of ring structure. In things like ringed lizards and worm lizards they are used like the rings of a telescope to move the body forward or backwards, however I am fairly certain these ring like sections occur in other types of animals as well.

A polygon is a two-dimensional shape enclosed by lines only, not curves. So triangles, squares, rectangles, and octagons are examples of polygons. Circles, ellipses, and annuli are some shapes that are not polygons.

The segmented worm genus is known as "Annelida." These worms have bodies made up of repeating segments called "annuli." Annelids encompass various species including earthworms, leeches, and marine bristle worms.
There are no polygons (shapes with only straight-line sides) with fewer than three sides, but if you allow shapes with curved sides there are many possibilities. Examples include semicircles, annuli (donut shaped), and crescents.From Caromal, and Izzyk9God just say a CONE!!!
A donut chart is simply a double pie chart with the inner and outer annuli repreenting breakdowns of two related totals. The totals may be related in being the same variable for two entities or the same variable at two different times.
The gear train consists of an alular gear ring on shaft, connected to the other by "sun" and "planet" gears within the annulus. Gear changing is achieved by having one set per ratio, controlled by brakes on the annuli to bring the desired set into use. The term 'epicyclic' refers to the geometry of the gear-box.
The ridges on a worm, often referred to as annuli or segments, serve several important functions. They help to create a segmented body structure, allowing for greater flexibility and movement as the worm contracts and expands its muscles. Additionally, these ridges can assist in locomotion by providing traction against the soil, enabling the worm to navigate through its environment effectively.
According to SOWPODS (the combination of Scrabble dictionaries used around the world) there are 5 words with the pattern A---LI. That is, six letter words with 1st letter A and 5th letter L and 6th letter I. In alphabetical order, they are: alkali annuli argali arguli arilli
They are composed of 2 or 3 leaflets, each with a fibrous core that is continuous with the annuli fibrosi (fibrous rings of the heart that surround the openings of the heart and serve as attachment sites for cardiac muscle as well as the bicuspid and tricuspid valves)of the cardiac skeleton. They are covered on both sides by fibrocartilage and a thin epithelium. Cordae Tendineae connect each leaflet of the atrioventricular valves (mitral + tricuspid) to the muscular projections (papillae) from the wall of the ventricle and prevent them from prolapsing into the atrial chamber during ventricular contraction.
