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.

If you spit up blood you need medical treatment as soon as possible.
