@DavidBrown I've been stuck at 10 since getting Neotropical and then Marine Otter at Los Ocarros and then Huachipa in 2012. I had never seen a wild otter until 2020 and have managed 6 of these 10 wild since then (bolded)!
@Nix I haven't really! Was a possibility for one section of my Uganda trip last year, but we "only" saw Spotted-necked Otter. Looking on mammalwatching.com I saw one trip mention seeing them in Gabon.
