Matthijs Kuijpers is a Dutch adventurer and photographer. He spent the last 27 years traveling and taking pictures of the most dangerous, surprising and endangered cold blooded animals out there.

Matthijs collected his best shots in his first book: COLD INSTINCT. In order to make this a reality, he just launched a crowdfunding campaign.

This book is an unparalleled collection of some of the most peculiar species that has ever crawled or slithered on Earth; and some of which are carefully dwelling in the most hidden crevices of the Planet!
