Description:
A large sturdy animal, this snake has black to brown dorsal
coloration with light colored crossbars numbering from 17 to 36 on
the body and 5 to 11 on the tail. The crossbars themselves can be
white, cream, silvery gray or tan. The cross bars can be from 1 to 3
scales wide and the scales within the bands may have dark tips.
Lateral light markings on the snake’s flanks connect the bars to form
a chain-like pattern, giving credence to its name. The coloration is
variable with irregular combinations of dark and light patterning.
The scales are very polished looking, hence the genus Lampropeltis,
which means literally shiny skin. The pattern on the head is
also very variable with most of the head scutes containing some light
marking and the labials vertically bi-colored giving them a
tiger-stripe like appearance.
Chain Kingsnakes can look
fairly different from area to area. Bi-colored scales in wider
crossbars can make this snake look very different from those with
thinner bars or no bi-colored scales. Snakes from the Hatteras
National Seashore area in North Carolina have many bi-colored scales
in the dark areas between the crossbars giving them a speckled
appearance. This population once was described as L.g.sticticeps.
Specimens from some areas around Jasper County, South Carolina have
very reduced lateral markings so as to give them a ringed appearance.
Adult Chain Kingsnakes are
from 34 to over 48 inches long with the record being 82 inches. Males
tend to be larger than females. These powerful animals have a fairly
cylindrical body with an indistinct head. The tails tend to be
somewhat short and thick making gender determination difficult
without probing.
Young kingsnakes look almost
identical to the adults though they usually have proportionately
longer heads. Some juveniles have some red or orange mottling in the
light flank markings.
Chain kingsnake dorsal scales
are smooth and number 21 at mid-body and 19 on the tail. There are
200 to 222 ventrals and 35 to 55 subcaudals.
Biology and Behavior:
Chain Kingsnakes are mild tempered
animals that, although shy, become quickly accustomed to humans. When
first picked up they may struggle or attempt to bite but often settle
at once and will then tolerate handling. We have observed that most
of the time there will be some struggling with smaller snakes being
more disturbed than larger ones. Like many snakes, Chain Kingsnakes
will usually secrete musk and vibrate their tails as a preliminary
defensive gesture.
Most accounts of these
animals describe diurnal behavior. We have yet to see anything
contradictory in the field, but captive animals move throughout the
night. When we have discovered these snakes under sheltering objects,
it has always been in the afternoon or evening. Past research
describes Chain Kingsnakes as semi-fossorial and many captive
specimens that we have held prefer to cover themselves in the
substrate.
Chain Kingsnakes will eat
just about anything of appropriate size that it can catch. Rodents,
lizards, birds, turtles, eggs (especially turtle eggs) and amphibians
are just a few items. Chain Kingsnakes have relatively small mouths
and are really bad at catching rodents, though they certainly try.
Based on this and their preferred habitat, watersnakes probably make
up the bulk of their diets; turtle eggs are too seasonal to be a
staple and turtles themselves are too big and difficult to hold,
except for hatchlings. In captivity, glass lizards (Ophisaurus)
cause an extremely aggressive feeding response in these snakes and
probably also are frequent prey. Kingsnakes are not deterred by
venomous snakes and will readily make a meal out of one. Observations
seem to indicate that they are extremely tolerant of snake venom and
venomous snakes often do not even attempt to bite them, but instead
attempt to hide their heads and use coils to fend off the attacking
kingsnake.
In the coastal plains,
kingsnakes start mating in mid April through early June. Females can
be sexually mature at about three years and 30" long and males mature
a little more quickly. Gestation usually lasts 40 to 60 days, after
which 3 to 30 eggs (12 to 15 being an average clutch) are laid.
Hatching occurs after 8 to 12 weeks, depending on the environment.
Chain Kingsnakes are fairly
long-lived animals with life spans reported as high as 21 years.
Range and Locality Data:
There are many subspecies of common
kingsnakes with the Chain Kingsnake being the only one in the range
covered by this book. Common kingsnakes span the entire United States
and can be found in 27 states and Mexico. The Chain Kingsnake ranges
from Southern New Jersey, south to central Florida and west to the
Appalachians. Records come from almost every county in Coastal Plains.
Chain Kingsnakes are almost
always found in wet areas and have a preference for standing water.
Generally shy they stay close to sheltering foliage or near holes or
burrows where they can quickly disappear should danger threaten. They
can be quick to adopt man made habitat and don’t seem to shy away
from agriculture, though most other forms of habitat destruction
seems to push them out.
Chain Kingsnakes seem to be
fairly abundant as there are hundreds of records of them through out
the region. Although few records come from suburban areas, and almost
none from urban areas, rural areas seem to yield large numbers of
these snakes, especially on the roads. In undisturbed areas, careful
and diligent observation will reveal many kingsnakes.
