females are larger, and can grow to 10 or 12 feet.
It has a gray belly with dark spots. The rest of the snake has a brownish or

white. The head, from the neck to the very tip of the snout, is accented with a
dark line on either side. Another line runs from the eyes to the tip of the neck.

Boa Constrictors are nocturnal, and are found both in
treetops and on the ground. They are extremely active
and will need branches or shelves in their cages when
they are kept in captivity. Though they have fairly
docile temperaments, they should be handled with caution.
They can be aggressive if nervous or frightened. They
may hiss when they are startled. If kept as pets, they
need fresh water available at all times and love to
soak in their water bowls.
