14- The Gulf Coast horned lizard (Phrynosoma wigginsi ) :

From Wikipedia, the free encyclopedia


The Gulf Coast horned lizard (Phrynosoma wigginsi ) is a horned lizard species native to Baja California, Mexico.

Gulf Coast horned lizard

Scientific classification:









Species:P. wigginsi

Binomial name:

Phrynosoma wigginsi
Montanucci, 2004


Taxonomy :

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.


Etymology :

The specific name, wigginsi, is in honor of Stanford University botanist Ira Loren Wiggins, who in 1946 collected what later became the holotype.[1][2]


Geographic range :

The geographic range of P. wigginsi is restricted to the region around Mulegé and Loreto on the Gulf Coast side of Baja California Sur, specifically the eastern side of the Sierra de Guadalupe and Sierra de La Giganta.[1]



Habitat :

P. wigginsi lives in similar coastal desert habitats to its close relative P. coronatum, but unlike more distantly related members of the genus. This alignment has been used to illustrate the principle of niche conservatism.[3] It preys on ants and other invertebrates, and, like other Phrynosomatid lizards, has the remarkable ability to squirt blood from its eyes as a defense.[4]
