Mystery organism photo of the month — November By Hilary Miller • 13/11/2009 This post was syndicated from The chicken or the egg - View original source There are two organisms in this photo… who can tell me what the small round scaly things are? And for bonus points, whats the other organism in the photo? photo 0 Responses to “Mystery organism photo of the month — November” Just a guess – ticks or mites of some kind? On a reptile (maybe a tuatara)? Correct! Amblyoma sphenodonti, an ixodid tick specifc to tuatara. Like its host, its quite genetically divergent from its closest relatives. It also has a much more restricted distribution than tuatara – being found in only around 8 (out of 30-odd) tuatara populations.
