Yes. Sand boas are vertebrates as are all snakes.

I say that some types of birds eat Sand Boas
in dry placesEDIT: Boas are found all over the world. From Red Sand Boas of the Middle East, The Dumeril's Boa of Madagascar, the Emerald Tree Boa of South America. Green Anacondas and Yellow Anacondas are in fact boas that live in South America. In the U.S., there are two native types of boas: the Rosy boa and the Rubber Boa. boas in general inhabit a very broad spectrum of habitats.

No. Boas are constrictors and kill their prey via suffocation.
It depends what kind of boa. Red tailed boas reaches 7 ft or so sand boas reaches only 32 inches. Hope this answers your question.
Boas in general are not close to extinction by any means, but some specific ones like a subspecies of Sand boa (don't remember off the top of my head) are endangered).
Some do. The sand boa (all subspecies) is a burrower along with Rosy boas and some others. The Red tail boa (which is probably what you're thinking of) is semi arboreal to arboreal and does not burrow.
The main difference is - Rattlesnakes are venomous, while Boa constrictors are (as the name suggests) constrictors.
yes, thery rattle - to distract the enemies from attacking it's head, which it noramally burrows into sand.
They don't, they live in tropical habitats. Some species of boa live in deserts, such as sand boas.
