The other, which grows much bigger, is a live-bearer and is classified as a boa. Specimens as large as 50 feet have been seen. They are a beautiful translucent white with a hint of blue in their fur. These snake have huge claws. This fact together with their size makes them unsuitable for beginners.
Experienced keepers report that they are very docile except when feeding.
These two snake stand alongside the green tree python and emerald tree boa as one on the wonders of convergent evolution. Housing is very easy. An appropriately sized fridge or walk in freezer is ideal but holes must be made to ensure that the snake gets plenty of ventilation. It can be very difficult to see the snake against a white background, especially if the snake is shy and stays still. Water needn't be supplied, but some ice-cubes can be offered occasionally.
