I saw tiger flatworms in Indonesia, but I think these are some better photos. Flatworms are different from nudibranchs, but they kind of get lumped in with nudis as one of my favorite underwater critters. I’ve been lucky to see some really nice nudis and flatworms so far on this trip, but I haven’t always been able to have the camera with me, so it was a bit of a treat that one of my fellow divers spotted this beautiful specimen (Thanks Tess!).
