I'm Mark Rosenstein. Contact me by email to mar at My handle here is pronounced "mar-ACT-win". I live in Cambridge, Massachusetts. If you're visiting the Boston area, message me if you'd like a local hiking companion.

I make a lot of identifications here on iNat, mostly on Indo-Pacific reef fish and North American butterflies and moths. I'm less good these days at including comments when I disagree with another ID. Feel free to ask for more information. I'm pretty good about checking notifications here, though I also travel a lot and am sometimes completely off the net for a couple weeks at a time.

I'm an avid scuba diver, fish geek and underwater photographer. I like to be able to name everything I see on a tropical reef. I've published a field guide to the reef fishes of Fiji, called Fiji Reef Fish. More recently I've become obsessed with bird watching, butterflies, and odonates. Interested in a little bit of everything else too, as I try to become a more rounded naturalist. Though I still do not know many plants.

Some have asked about my underwater photography. I use a Canon 7DmarkII dSLR inside an Aquatica housing, with dual Retra strobes. I shoot mostly with a 100mm macro lens, though also shoot wide with either a Sigma 17-70mm under an 8 inch dome or Tokina 10-17mm fisheye under a 4 inch dome.
