If they do not try to escape, often they "play dead" by flipping over onto their backs and lying motionless.

Appearance

The snake's glossy dorsum is black or very dark brown colored, finely speckled with off-white or yellow. These pale flecks form dimly defined narrow vertebral crossbands, between which the intervening rectangular areas are black. Pale yellow scales may predominate along the lower sides. The abdomens of both adult and young snakes are mostly black, with white or pale yellow blotches marking the outer ends of the ventral plates. The smooth dorsal scales are arranged in 23 to 25 rows at midbody and the anal plate is undivided.

Family

The desert kingsnake belongs to the Colubridae or Colubrid family, the largest family of snakes in the world.

, ''L. splendida'' lays eggs. Courtship and copulation occur between March and June, with clutches of 5 to 12 adhesive-surfaced eggs deposited in late June or July, sometimes buried as deeply as a foot to prevent drying through their moisture-permeable shells. After about 60 days of incubation, the 8- to 10-inch-long hatchlings, weighing about a fifth of an ounce, emerge. Brightly yellow-speckled in vertebral cross-lines, they also exhibit a lateral row of large, dark brown spots, which as they mature, are gradually fragmented by encroaching yellow flecks.
