One of the most mysterious animals to inhabit the jungle is the pygmy hippopotamus - up to 300 kg in weight, just 2 meters long, and 80 cm tall, and a true loner. Since its discovery in 1844, generations of researchers have attempted to study it in the wild - but in vain. Although it proved possible to catch a few specimens for zoos, no one ever got to see them before they were already inside the trap. They eluded the gaze of the researchers like phantoms under the protection of the enchanted forest. These are the first ever pictures of pygmy hippopotami in their natural surroundings - the rain forest of West Africa. Set amid stories about their habitat, the film allows a first impression of this timid creature's life. While their ten-times heavier relatives are loud and gregarious and live in open stretches of water, the pygmy hippopotamus moves furtively through the thick undergrowth.

Chris Packham presents, mentioning others that didn't quite make the list, his favorite top ten animal - and plant species from the half million discovered in the first decade of the 21st century. The animals include the most endangered African monkey, a lemur (Madagascar simian), a mouse-size and -resembling relative of the elephant, a Caribean island-adapted sloth, a shark which 'walks coral reefs on an arm', the largest mega-stick, a deep sea jellyfish without tentacles and a jungle gecko mutation happening in Malaysian state Perlis in order to flee serpent predation into caves. Plant species include a giant Venus-flytrap on Palawan (Philipines) and the largest ever orchid from Peru.
