Aided by their prehensile tails, these snakes are good at climbing. Some big ones may even be active during the day. While active, younger boas are more likely to move through the trees while larger individuals tend to stay on the ground. The boa is able to be active at dusk or night because it can hold body temperature without basking in the sun. Males have more distinct ‘anal spurs’ than females and use them to stroke the female during courtship. Younger boas are brighter, and the splotchy pattern may blur as some grow into large adults.īoas fall into a group of primitive snakes that still have the bones of a pelvis and vestigial ‘legs ’ on the outside of the body-the only visual cue that these bones remain is a small horny spur on either side of the snake’s vent. After shedding an old skin, this snake is incandescent.
While it may sound like a blandly vested serpent, the boa’s scales can be brightly iridescent. The tail may be banded in different colors, particularly shades of red, yellow, or black. This snake is colored cryptically: the body is mostly light brown to gray with dark brown to black lateral patches with lighter centers.
Its head and dorsal scales are small and smooth. However, when it is found in Costa Rica, the huge boa constrictor is distinct secondly because it lacks labial pits on its head and has a dark brown stripe from its snout to its neck. It would be unusual to encounter the small, beige eyes close enough to see the vertical pupil. The boa ranges from Mexico along both slopes through Central America and down to northern Peru, Paraguay, and central Argentina. It can survive in shrub, savannah, cultivated fields, secondary growth in lowland dry, moist, and wet forests, and in premontane moist and wet forests. This large snake lives on the ground and in the trees from sea level to 1,000 m in elevation.
