One is called the clavus pattern or in French language oeil-de-perdrix.

This species also goes under the name Clavus viduus.

Flax clavus is a moth of the Micronoctuidae family.

Instead, it folds into itself as the creature matures, creating a rounded rudder called a clavus.

The rhinophoral clavus possesses 27 to 30 lamellae.

The males have a distinctive mark and a light yellowish colour base with black streaks starting from clavus to the forewing.

The small pectoral fins move constantly to control pitch, while the clavus is employed as a rudder.

The clavus of each rhinophore has 21 to 24 lamellae, and the rhinophoral pocket is trimmed in white.

Its description is almost identical to Clavus laeta (Hinds, 1843)

The narrow costal area of the wing has veinlets running almost the entire length, excluding the base region, and is longer than the clavus.

The dorsal and anal fins are slaty, while the clavus may have pale blotches.

The chiton often bears a decorative line (clavus), occasionally light red or light green, also sometimes gold, but normally in dark colours.

The skin on the clavus is smoother than that on the body, where it can be as rough as sandpaper.

Cantelius maintained that the clavus consisted of a kind of purple flowers, sewn upon the cloth.

Clavus clavata is a species of sea snail, a marine gastropod mollusk in the family Drilliidae.

Senators in mourning also wore a knight's tunic bearing the angustus clavus, or "narrow stripe," on its shoulder.

Senators alone were entitled to wear the latus clavus on their tunics; this was a broad purple stripe down the right shoulder.

The smooth-denticled clavus retains twelve fin rays, and terminates in a number of rounded ossicles.

The caudal fin of the ocean sunfish is replaced by a rounded clavus, creating the body's distinct truncated shape.

The posterior portion of the remigium is sometimes called the clavus; the two other posterior fields are the anal and jugal areas.

Later, the Sphacelia segetum convert into a hard dry Sclerotium clavus inside the husk of the floret.

Clavus maravignae (Bivona Ant.

The knight wore a narrow purple stripe, the angustus clavus, and those below the status of knights wore no stripe at all.

It is similar in appearance to the ocean sunfish (Mola mola), but can be distinguished by the projection on its clavus (pseudo-tail).

In the course of its evolution, the caudal fin (tail) of the sunfish disappeared, to be replaced by a lumpy pseudo-tail, the clavus.
