Gulf Coast horned lizard Gulf Coast horned lizard The Gulf Coast horned lizard ("Phrynosoma wigginsi" ) is a species of horned lizards native to Baja California, Mexico. "Phrynosoma wigginsi" was split from "Phrynosoma coronatum" in 2004 on morphological evidence. "P. wigginsi" has a tan rather than chocolate forehead, a fourth "subrictal" spine below the eye, and a longer head than "P. coronatum". The specific name, "wigginsi", is in honor of Stanford University botanist Ira Loren Wiggins, who in 1946 collected what later became the holotype. The geographic range of "P. wigginsi" is restricted to the region around Mulegé and Loreto on the Gulf Coast
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,
