Boas are ovoviviparous: females incubate 20–50 eggs inside their bodies and give birth to fully formed young.
 
Unlike other members of the Boidae family, boa constrictors do not have thermo-sensitive pits, but they can recognize warm-blooded prey thanks to the infrared-sensitive scales on the lips under their nostrils.
 
Tree-dwelling and nocturnal, boa constrictors bite their prey before squeezing them to death.
