Caecilians are the least known amphibians and most species are under threat due to urbanisation, habitat degradation and climate change. Here we report the fourth sighting of Ichthyophis hypocyaneus, in Gunung Halimun-Salak National Park. The individual was found in a flooded grassland and we described habitat and vegetation in the vicinity of the site. We hypothesized that it was either breeding or feeding as it was active at the site, and flooding had provided both breeding habitat and numerous preys. Although being a single sighting we would like to draw attention to the fact that no ecological preferences have been described for the species, and that such studies are urgently needed.
