Eastern indigo snakes are some of the largest snakes in North America; reaching a maximum

length, of 2.62 meters. Most records of wild specimens 2.4 m or longer have been from

southern Florida. The species is fairly stout-bodied and sexually dimorphic in size, with

males growing longer than females. Large males are typically 2.13-2.36 meters and

weigh 3.2-4.5 kg; while large females seldom exceed 2.0 meters and weigh 1.8-2.7 kg. Eastern

Indigo Snakes are a uniform bluish or gunmetal black both dorsally and ventrally. A wash of

orange-red is normally found on the chin, sides of the head, and throat. There is some

variation in this as in northern Florida; where some populations have black lip scales and a

white patch in the center of the throat rather than the orange-red. The orange-red pigment

is more prominent in male eastern indigos and may extend onto the belly of some south

Florida snakes. The common name for eastern indigos snakes relates to the large, smooth

scales of this species which appear iridescent purple in sunlight. Adult males have partial

keels on the scales of the total length of 2.62 m. Most records of wild specimens 2.4 meters or

longer have been from southern Florida. The species is fairly stout-bodied and sexually dimorphic

in size, with males attaining greater lengths than females. Large males are typically 2.13-2.36 m

and weigh 3.2-4.5 kg; while large females seldom exceed 2.0 meters and weigh 1.8-2.7 kg. Eastern Indigo
