The boa is a snake that suffocates is prey?

Yes it does.

The Boa Constrictor is a loving reptile: it will literally hug you to death.

The boa constrictor is not a poisonous snake. It suffocates its prey by wrapping around it, and with every breath of air the captive takes, the boa will tighten its grip until the victim suffocates.

The boa constrictor makes his home on the floor of many rainforest throughout central and South America, Trinidad and Venezuela. They range in size from three to twenty feet. The boa constrictor's colors of brown and cream help him blend in with the forest floor, you may also find him hiding in tree branches.

The boa constrictor's diet consists of any animal he can swallow. His favorites are mice, lizards, and frogs because there is an abundance of these and make a fulfilling quick snack.

The boas, when hungry looses all reason. He has been caught by farmers, because he squeezed through chicken wire to get to a hearty meal. But, after eating his fill, his body became too large to escape the way he came in. With no other escape he would be stuck. Farmers will kill the boa constrictor at first sight, because he preys on their chickens and other livestock.
