A shovel comprising: a lower traveling body including a pair of crawlers; an upper turning body turnably mounted on the lower traveling body; an image capturing device provided to the upper turning body and configured to capture an image around the shovel; an obtaining device provided to the upper turning body and configured to obtain information related to a situation around the shovel; a detecting part configured to detect a predetermined object around the shovel based on an output of the obtaining device; and a display device configured to display a peripheral image representing the situation around the shovel based on the captured image of the image capturing device, wherein a detectable area of the detecting part in which the predetermined object is detectable by the detecting part includes an entirety of a surrounding area in a circumferential direction as viewed from the shovel, the surrounding area appearing in the peripheral image displayed on the display device, wherein areas located in a moving direction of the crawlers, in a state in which the upper turning body is turned and an orientation of the upper turning body does not coincide with the moving direction of the crawlers, are included in one or both of the detectable area of the detecting part and a displayable area that is displayable on the display device as the peripheral image, and wherein the areas located in the moving direction of the crawlers, when a turning angle of the upper turning body with respect to the moving direction of the crawlers is turned relatively large within a range where the turning angle is smaller than 90 degrees, are included in one or both of the detectable area and the displayable area. a lower traveling body including a pair of crawlers; an upper turning body turnably mounted on the lower traveling body; an image capturing device provided to the upper turning body and configured to capture an image around the shovel; an obtaining device provided to the upper turning body and configured to obtain information related to a situation around the shovel; a detecting part configured to detect a predetermined object around the shovel based on an output of the obtaining device; and a display device configured to display a peripheral image representing the situation around the shovel based on the captured image of the image capturing device, wherein a detectable area of the detecting part in which the predetermined object is detectable by the detecting part includes an entirety of a surrounding area in a circumferential direction as viewed from the shovel, the surrounding area appearing in the peripheral image displayed on the display device, wherein areas located in a moving direction of the crawlers, in a state in which the upper turning body is turned and an orientation of the upper turning body does not coincide with the moving direction of the crawlers, are included in one or both of the detectable area of the detecting part and a displayable area that is displayable on the display device as the peripheral image, and wherein the areas located in the moving direction of the crawlers, when a turning angle of the upper turning body with respect to the moving direction of the crawlers is turned relatively large within a range where the turning angle is smaller than 90 degrees, are included in one or both of the detectable area and the displayable area.
