They spit blood out there eyes by putting their eyes behind their head and use heat to draw blood out their eyes.
Yes!:)Some species of horned lizards can shoot blood from their eyes when they burst tiny blood vessels within the eyes. This only happens when the lizard feels threatened.
There are no Iguanas that 'spit blood'. I think you're referring to the horned lizard - which, as a defence mechanism, has the ability to rupture the blood vessels at the corner of its eyes - shooting a stream of blood at an attacker.
They don't. It is a misconception that thorny devils shoot blood out of their eyes. The Texas Horned lizard, Coast horned lizard, and at least two other species, none of which are Thorny devils, will shoot blood from their eyes as a defence mechanism.
Horned lizards spray blood from the corners of their eyes in self defense. Camels sometimes spit, not always in self defense, but sometimes it is in self defense. Chinchillas spray in self defense. Some snakes spit in self defense, and so do cats. Skunks spray a liquid from their anal sacs in self defense.
they do not spit out stuff that will do anything so no
