This is a chameleon.
He can swivel his eyes to look at you without even moving his head.
He particularly likes to stare down grubs, because he thinks they are yummy.
He shoots out his long sticky tongue to catch the grubs and pulls them back into his mouth before they even know what happened.
The tip accelerates at more than 50g and reaches a top speed of over 20 km/h.
Which is really fast for a tongue.
He takes his time eating the grub once it is in his mouth though.
Great action shots! But gross!
