Whenever anyone who owns a boa mentions to a non reptile owner that they keep boa constrictors, the listener always assumes that the owner has a huge and dangerous constrictor, threatening life and limb of the family, and within a few minutes the old story of the snake lying down next to its owner to size it up is trotted out.
Of course most boas are much smaller than popular imagination would have it, and some not much bigger than grass snakes or small adders.
We have a number of small constrictors in our collection, of which perhaps the tropidophis melanurus, or Cuban giant dwarf boa, is the smallest, reaching less than 3 foot in length.
These are a difficult snakes to get feeding when juvenile but are rewarding to keep.
We also have Chilabothrus Fordii, or Haitian Ground Boa. These achieve about 3 foot in adulthood. These are a very slender snake, and again difficult to get started on frozen food.
