Growing up to 2.5m in length, Perentie’s (Varanus giganteus) are Australia’s largest lizard species, and one of my absolute favourite species of varanid. They have incredibly distinctive markings on their throats, which they like to puff out (along with the occasional hiss) to let you know you’re an unwelcome visitor. These perenties were found in the Mid West region of Western Australia. One was approaching full size, and the other was a juvenile (but already over a metre long!).
