Tomorrow the British Broadcasting Corporation will show the first episode of a new documentary, “The Dark: Nature’s Nighttime World,” highlighting Costa Rica’s diverse nocturnal wildlife.

Scheduled for 4:15 p.m. (which would be 10:15 a.m. in Costa Rica) on BBC Two, the “Central America Jungle” episode brings viewers up close to Costa Rica’s rarely seen jaguars, tapirs, opossums, sea turtles, kinkajous as well as remarkable spiders and insects as they roam and prey at night.

“The expedition starts in the jungles of Costa Rica where the team are after some of the most frightening nocturnal predators. Alone in the dark, nighttime camera specialist Justine Evans has an exceptionally close encounter with a large male jaguar,” said the BBC.

Biologist Dr George McGavin gives viewers a rare glimpse of “the most ingenious predator of the jungle – the net casting spider,” in the hour-long show.

Over six months, biologists and a specialist camera crew explored South and Central America to find out how animals have adapted to life in the dark.

The second episode, “Amazon Flooded Forests,” will screen at the same time Thursday. The third and final episode, also focused on South America, is “Patagonian Mountains,” to air Friday.

The film can be downloaded for a charge from iTunes, said the BBC at the documentary site: http://bbc.in/1X7SO0Y.
