There are a few species that have cast aside the scavenger ways of their compatriots, opting for more relaxed arboreal lifestyles, spending their days high in the tree tops foraging for fruit. These frugivorous monitor lizards are are joined by a serpentine Species of the Bi-week. FULL REFERENCE LIST AVAILABLE AT: herphighlights.podbean.com
