  > The V. panoptes burrows start with a short sub-horizontal section, then have a long curving, descending section, at the end of which is a descending vertical helix that can have as many as eight convolutions. Some of the helices are clockwise, others are anti-clockwise, and some switch from one direction to the other (Doody et al. 2015). ok, that’s what i wanted to know. Monitor lizards are racemic.
