8 Episodes 0 - 2010
Episode 1
As with all Seahorses, it is the male Leafy Sea Dragon that is responsible for parenting. Arriving in Australia just after breeding time means that Nick could very well see their young; a rare sighting of an extremely endangered fish.

Episode 2
We take a road trip through Mexico's Baja peninsula in search of the elusive Mole Lizard (a.k.a Five-toed Worm Lizard). Through its evolutionary journey it lost its rear limbs, leaving a creature that looks like part snake, part lizard and part earthworm.
Episode 3
The Axolotl is a type of salamander that Nick has kept as a pet for two decades. He learns about its unique biology that holds great promise for medical science, and discovers how Mexico City's development has driven this creature to the edge of extinction.
Episode 4
Nick travels to Australia's Red Center in search of one of the world's weirdest desert diggers, the Marsupial Mole. As temperatures in the Outback soar over 100 degrees, Nick searches for clues and looks for tracks using seismic sensing devices.
Episode 5
Travel to the depths of the Bornean jungle to find the only poisonous primate in the world: the Slow Loris, which lives in the towering rainforest canopy. It looks like a cuddly toy, but it carries a poison in its bite that can prove fatal.
Episode 6
In the Delaware Bay, Nick tracks down one of the oldest creatures on the planet: a half billion-year-old living fossil that is currently in danger. He hopes to witness one of nature's most spectacularly weird spawning events.
Episode 7
Luck is on Nick's side as he goes in search of the awkward middle child of anteaters, the tamandua. He also gets more than he bargained for when he stumbles across a battery of army ants.
Episode 8
Nick heads to a group of desert islands in Panama where strange things have been happening to the animals. He hangs out with the pygmy sloth, a species only identified in 2001, and discovers a species of frog with an identity crisis.
