They result from the beetle's efforts to get itself back into take-off position for flight when it has been in either lateral or dorsal position.

The fecal groove spirals across to the dorsal position as it reaches the thoracic region.

Due to technical problems with the armament installation, many aircraft went to operational units with only a light machine gun in the dorsal position.

After this period they were buried on their backs (dorsal position), and from the Fifth Dynasty the bodies were always fully extended.

The siphuncle starts off ventrally, like that in other ammonoids, but after the first few septa migrates to a definite and stable dorsal position.

Female survivorship of attacks by predators is significantly enhanced by pairing, largely because the dorsal position of the male functions well as a shield.

Defensive armament consisted of three machine guns, situated at the nose, at a dorsal position and within a retractable ventral position.

Armament: four 7.9 mm Vickers F machine guns on ring mountings in fuselage nose and in a dorsal position.
