Boa constrictor amarali
Subspecies Boa constrictor amarali belongs to smaller forms of Boa constrictor
and captive breed is not as common as by other variants. This subspecies was
defined by Stull in 1932. In Europe we can say relatively rare. Boa constrictor
amarali area of range is in narrow band around Sao Paulo down to Bolivian part
of Pantanal. For these Boa constrictors is typical butterfly pattern and very
short tail with a few saddles.
Head of this beautiful subspecies is quiet robust and thank to its size seems
to be dumpy-looking. Exemplars with ash-colored ground are called “silverbacks”.
These Boa constrictors are from area near Sao Paulo and from several localities
in Bolivia. They are one of the original blood stream in amarali subspecies,
in Europe called Danish Bloodline.
Brazilian form of Boa constrictor amarali includes as classic silverbacks as
more colored exemplars. Breeding of this subspecies is more complicated than
for example Boa constrictor imperator. By Sao Paulo population and Danish
Bloodline was identified vomiting trend caused by not exactly defined reasons.
Trend can be caused by non-relevant breeding conditions as temperature and
humidity, but can be also caused by feeding improper prey size. Therefore is
generally more suitable to buy and breed Boa constrictors amarali from CB than
wild caught. Stress from animal adapting from nature to “cage” can add more
negative influences and increase the danger of healthy problems up to death.
Exemplars from this area are in youth cinereous, adult are getting bronze up
to light brown. Western exemplars of Boa constrictor amarali usually have
very nice contrast coloration.
About Bolivian Boa constrictor amarali we can write almost the same as about
Brazilian ones. In this range are as silverbacks as contrast colored exemplars
near bronze and brown. For locality breeding is generally good to keep the
parental Boa constrictors amarali from significant localities and not to
crossbreed animals from different areas.
