Boa  constrictors  are  large  heavy  snakes  which  are  native  to the  New World  and  can  grow  to  a  length  of  between  3-13  feet.  They  are  non-venomous  predators  and  can  eat  a  range  of  small  mammals,  rodents and  birds.  Their  preferred  method  of  hunting  is  to  wait  for  their  prey  to walk  within  reach  when  they  then  strike  out  with  their  mouths  and  grab the  animal  with  their  short  backward-pointing  teeth.  Simultaneously the victim’s body is wrapped in their constricting coils, and the prey soon dies of suffocation before it is swallowed whole.
