Hog Islands were among the first of the Locality Boas that we obtained. We started with a pair of 2010. The female is a slightly reluctant feeder and therefore is a little smaller than the male and is much more orange. The male really shows the Hog tendency to become increasingly pale during the evening.
We then obtained a second female, a 2009. She again was comparatively small, even for a Hog, but has steadily increased in size since we have had her. She is a much lighter colour than the other two.
