Giant 'meat-eating' plant produces traps big enough to catch rodents

A giant carnivorous plant found only in Mount Victoria, Palawan in the Philippines, has been named Nepenthes attenboroughii, after renowned British naturalist and broadcaster Sir David Attenborough.

Some of us were this close to forgetting the very existence of Rick Moranis. Thanks a lot, Hactar.

"The pitcher plant is among the largest of all pitchers and is so big that it can catch rats ..."

... and rats there are probably the size of children.

Hmmm, Lush, aren't you headed there in a few months? Maybe you could pick one up for me. If the landslides don't get you first. :)

Nowhere does it give the size of the plant... nor show it along with anything that gives some scale.. I suspect this thing is about 6 inches tall....

I'm conflicted. I hate rats, but feel I should stick up for a fellow mammal against something that's not even an animal.

HuronBob, in the Wikipedia article which cites the Botanical Journal of the Linnean Society, it says:
"The stem, which may be up to 3.5 cm thick, is circular in cross section and attains a height of up to 1.5 m."

"The lower pitchers are brittle and campanulate (bell-shaped), up to 30 cm tall and 16 cm wide and emerge from tendrils that are 30-40 cm long and 4-9 mm in diameter.... The upper pitchers are similar to the lower pitchers, but generally infundibular, to 25 cm tall and 12 cm."

Of course, "nepenthes" means forgetfulness. So it's actually named "forget attenborough".

The wikipedia link gives tons of size info.

I'm having difficulty believing that this plant actually does catch rats (as opposed to being "big enough to"). A rat dropped in a bucket of water will drown, but if the bucket is made out of a leaf? Doubtful.

Actually, it means "without sorrow." But forgetting everything is a good strategy for becoming sorrow-free.

And blue mushrooms too. Trippy.

Pitcher plants are more than just leaf buckets that some little creature inadvertently fall into. Some have scents and visual lures to attract prey. Sometimes the walls are slippery or sticky. Sometimes little hairs aim downwards and prevent escape. Sometimes an hourglass shape makes escape more difficult. Then there is the nasty, bacteria filled liquid at the bottom that starts to digest you before you are even dead. Lovely stuff.

Nepenthes attenboroughii is a lovely name and made me wonder how the pitcher-plants got christenened 'Nepenthes'. It's all thanks to Linnaeus, apparently:

The name Nepenthes was first published in 1737 in Linnaeus's Hortus Cliffortianus. It references a passage in Homer's Odyssey, in which the potion 'Nepenthes pharmakon' is given to Helen by an Egyptian queen. 'Nepenthe' literally means 'without grief', and in Greek mythology, is a drug that quells all sorrows with forgetfulness. Linnaeus explained:

'If this is not Helen's Nepenthes, it certainly will be for all botanists. What botanist would not be filled with admiration if, after a long journey, he should find this wonderful plant? In his astonishment, past ills would be forgotten when beholding this admirable work of the Creator!'


'Linnaeus had no idea of the carnivorous nature of the plant .. Like many others for years to come, he assumed the unusual pitcher leaves to be water-holding devices to help the plant survive drought.' (Peter D'Amato, The Savage Garden.)

In his belly you will find a new definition of pain and suffering as you are slowly digested over a thousand years...

This is very cool. I like the props to Attenborough, and the blue mushrooms are indeed trippy. I'd love to see a pic of the blood red plant described at the end of the article, too.

I've really been enjoying David Attenborough's Life Stories, 10 minute radio broadcasts By Sir David Attenborough about plants and animals and filled with personal anecdotes. That man has had an amazing life.

I wasn't imagining the rat climbing out, I was imagining it tearing its way out.

This could be a problem for the ultimate survival of the rat, but unless it's pretty fast it won't save the plant.

When I read this, I thought it can't be the first time this has happened, and it isn't:

Materpiscis attenboroughi
Zaglossus attenboroughi


Also, given the number of obit threads recently, I was a bit scared that the post was going to read '...after renowned British naturalist and broadcaster Sir David Attenborough was eaten by one.' Phew.

micketymoc, yep, and Palawan sounds even more exciting now. I want one of these as a mousetrap! And those bright blue mushrooms...

I wasn't imagining the rat climbing out, I was imagining it tearing its way out.

From verstagen's link: "The trap contains a fluid of the plant's own production, which may be watery or syrupy and is used to drown the prey.... The trapping efficiency of this fluid remains high, even when significantly diluted by water, as inevitably happens in wet conditions. ... The lower part of the trap contains glands which absorb nutrients from captured prey. Along the upper inside part of the trap is a slick waxy coating which makes the escape of its prey nearly impossible. Surrounding the entrance to the trap is a structure called the peristome (the "lip") which is slippery and often quite colorful, attracting prey but offering an unsure footing."

So provided that the rat doesn't drown in the fluid that's the pitcher is likely filled with, it's in a flexible, cone-shaped well with waxy coating on its walls. It's not hard to imagine that a rat would find it difficult to get a good enough grip on it to climb, much less sink its teeth into - and all while the viscuous fluid at the bottom (that a different article says doesn't mix with rainwater) is already trying to digest it alive.

I've grown Nepenthes. The pitchers are pretty leathery. I can believe that a rat would not be able to chew its way out before drowning.

I love hot Mr A creeps up on the plant in the video, as though he's trying to avoid it spotting him.

If there were an anthropomorphic God, I bet He'd be a lot like David Attenborough... the man describes nature with a sincere, joyous fascination with how awesome it is.

Is it just me, or does anyone else find those plants rather creepy looking? A friend and I owned Venus Flytraps as children. But these pitcher plants just give me a chill. They look a bit otherworldly.

Yeah I know, but plants that snap shut don't bother me. Go figure.
