Spotted yesterday in Pemberton by local herpetologist, Leslie Anthony, the rubber boa
out sunning itself taking a moment to enjoy life outside the winter den.
Here are a few cool facts about the rubber boa, courtesy of BCReptiles.ca:
- they look like a rubbery tube, thanks to their loose skin and small smooth scales
- they’re usually between 35 and 80 cm long, and dark olive green to brown in colour, with pale yellow bellies
- they’re also known as a “two headed snake” because it’s so hard to tell their top from their tail – they have no neck and tiny eyes, and often use their tail as a decoy
- sluggish and secretive, they never bite and are happiest hiding beneath a damp log
- they can live up to 30 years, which is quite long-lived for a snake
- they belong to the same family as pythons and anacondas, and will wrap themselves around mice or shrews until their hearts stop, before dining on them. They also eat baby mice live, bird eggs, nestling birds, nestling rabbits, small lizards, other snakes, salamanders, small chipmunks and bats, and are able to swim, climb and burrow in search of food.
- they hibernate all winter in communally-shared underground dens called hibernacula
- spring is the season for mating
- pregnant females carry their young until mid-August when 1-8 earthworm like newborns emerge
- they prefer to live in humid mountainous areas, burrowing into loamy or sandy soils, or setting up base in abandoned rodent burrows, rock crevices, rotting stumps, logs, bark, litter around development, and decomposing sawdust piles.
- scientists have found that boas can select rocks of a certain thickness to rest beneath in order to thermoregulate more efficiently.
- they species is listed as a species of special concern federally because of their low reproductive rate and patchy distribution of habitat.
