Ichthyophis mindanaoensis occurs in lowland and submontane primary and secondary rainforests at elevations of
above sea level, and probably higher. It has also been recorded in agricultural land adjacent to remnant natural forest patches. Adults are subterranean and have usually been observed under rocks, decaying logs and debris, and in shallow pools of mountain streams, but also in soil beside irrigation ditches. The larvae occur in unpolluted streams, rivers, and quiet pools near streams. This species has a very localized and patchy distribution, but it can be relatively abundant where it occurs. It is threatened by
habitat loss and conversion, although it seems to be fairly adaptable, and might thereby not be significantly threatened, except locally. Furthermore, caecilians often killed because they are mistaken for snakes.
Ichthyophis mindanaoensis is known from
Mount Kitanglad Natural Park, Malagos Watershed Area, and
Mount Apo Natural Park, all relatively well protected and enforced areas. ==References==
