Never, if the rosy boa that eats the other will die in a coma.EDIT: Rosy boas are not by any means cannibalistic.
Rosy Boa IS the common name - it's given scientific name is Lichanura trivirgata
Like all other snakes, rosy boas are vertebrates.
yes
There are several animals that eat rosy boas. These include owls, foxes, roadrunners, and coyotes. Rosy boas are most vulnerable to these animals because the snake is active at night.
A Boa can be a type of snake that may grow up to about 20 feet in length. A Boa is also a long fluffy scarf made of soft material, such as fur or feathers - ofcause these can be made any length.EDIT: The most common boa (in the pet trade), the Red Tail Boa, reaches a range of 6-12 ft., depending on locality (Argentinian, Hog Island, Colombian, etc.). The longest boa is the Green Anaconda. The shortest I would say is some species of sand boa.
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.
No. Most boas are tropical where the temperature is relatively sustained year round. However, the Rosy boa is an example of a brumating (they don't hibernate) boa. It stays dormant through much of winter, coming out only on warm days.
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.
You could at least try they are all boas
rosy boas eat 1day old mice if they are a baby and as they grow-up they eat bigger things like rats the size of your arm including the tail!!
There's no need - the 'mother' snake has no maternal instinct towards its offspring - and the young snake is completely independent from the moment it was born.
