| 1. |
Like all snakes, boas are excellent swimmers, but
they usually avoid going into the water as much
as possible. |
|
|
| 2. |
Boas are considered primitive snakes, differing
from other species by having two vestigial, or remnant,
hind limbs. These vestigial limbs appear as spurs
on either side of the cloaca. |
|
|
| 3. |
Boas have special pits on their face that allow
them to detect heat. This is very important because
these snakes are nocturnal hunters that use this
ability to find warm-blooded prey at night. |

|
Rainbow boas are one of the most sought after
exotic snake for the pat trade because of their
iridescent skin. Over collection and rainforest
destruction for agriculture, ranching, and development
has significantly decreased their populations.
Boas
are very important in controlling rodent populations,
which, when in excess, can have a serious deleterious
effect on the environment.
