Blainville’s horned lizard (Phrynosoma blainvillii) has an eye-opening protection tactic: it will possibly actually shoot blood from its eyes! When threatened, these spiky little reptiles can rupture blood vessels positioned behind their eyes, squirting blood to discourage predators. However there’s extra to those quirky critters than simply their distinctive superpower. Discovered solely inside a restricted vary of California and northern Baja California, Mexico, these lizards are tailored to habitats like coastal sage scrub, chaparral, oak woodland, riparian woodland, and sandy dunes, from sea stage as much as 2,248 meters—nonetheless, with a love for sunbathing in open areas and burrowing into advantageous, sandy soils, they’re choosy about their environment.

Blainville’s horned lizard can also be a choosy eater. As dietary specialists that primarily feed on native harvester ants (ants that predominately forage on seeds), Blainville’s horned lizards are delicate to habitat perturbations as a result of they rely upon a narrower vary of meals sources than generalist species. Invasive species just like the Argentine ant (Linepithema humile) outcompete and displace native ants, thus decreasing the provision of Blainville’s horned lizard’s main prey. Though Blainville’s horned lizards are myrmecophagic (ant and termite consuming specialists), they gained’t contact Argentine ants.

City developments, agriculture, nonnative annual grasslands, and different types of habitat alteration and destruction are placing the squeeze on Blainville’s horned lizard too. As their pure habitats are destroyed or grow to be degraded, the locations they should hunt, disguise, and hang around are disappearing. Conserving their pure habitat and implementing restoration initiatives that plant native vegetation, handle soil situations, and battle again in opposition to invasive species can create lizard-friendly areas that assist them thrive.

Given all these challenges, it’s no marvel Blainville’s horned lizard has earned a spot as considered one of California Division of Fish and Wildlife’s Species of Particular Concern. It’s a name to motion to guard this distinctive creature and the habitats it calls residence. By defending or restoring their surroundings and supporting their dietary wants, we’re not simply saving a species — we’re guaranteeing that the wild, bizarre wonders of California endure for generations to come back!
