If teeth break off, they can regrow them. The teeth point backwards into the snake’s mouth, acting like hooks that don’t let go once the boa bites down. Their Teeth Point Backwardsīoa constrictors have curving, needle-like teeth designed to grip prey and prevent escape. Females can have litters of 10-65 baby boa constrictors at a time. This means they retain eggs inside their bodies until they are ready to hatch, at which point they give birth to live young. Unlike some snake species that lay eggs, boa constrictors are ovoviviparous. The remnants of legs likely help boas grasp and constrict prey as well. These pelvic spurs are claw-like protrusions on their bellies that male boas use during mating. One of the most interesting facts about boa constrictors is that they still have vestigial hind legs left over from their evolutionary ancestors. Other snakes like emerald boas and rosy boas may be called “boas” but are not actually Boa constrictors.
