In the past it also occurred in adjacent Canada. Like other horned lizards, it is often called a "horned toad" or "horny toad," but it is not a toad at all. It is a reptile, not an amphibian.

Holdridge's toad favor massy stream banks. The forest, wetlands, and/or pasturelands are sufficient enough for the Holdridge’s Toad. Due to the fact that the Holdridge’s toad is reappearing from assumed extinction, research is beginning on this small organism. Revival of past research gives current research scientists direction of what to discover and learn from this toad. From collected past and new research along, as the Holdridge’s is exposed to Costa Rica’s rainforests’ bacteria and fungus, the diet can be inferred. The Holdridge's toads’ diet include a broad range of arthropod invertebrates which includes spiders, larval stages of moths and butterflies (lepidopterans), flies,
