The male lava lizard is larger then the female and they look distinctly different. The overall color patterns are different, and females have bright red skin under their throats. The males are territorial and will protect their territories from other males. They will threaten intruders by doing "push-ups" (video of lava lizard push up coming soon.)
The food chain for these lizards is not very complex. Lava lizards are omnivores and eat moths, flies, beetles, ants, spiders, grasshoppers, and some plants. They are eaten by hawks, snakes, mockingbirds, herons, and centipedes. Besides camouflage, they have one major defense mechanism to help keep them from joining the food chain, by being eaten by a higher animal: they will "drop" their tail when a predator grabs hold of it. The dropped piece of tail will continue to move about while the lizard attempts to flee. Click here to see a lava lizard with a new tail growing in. A new tail will grow back to replace the old tail. This defense mechanism allow these lizards to live up to ten years. Sometimes the tail will grow back wrong. Click here to see the two tailed lizard that we saw.
