Venus Flytrap Shows Off "Two Hair Trip" Mechanism

0

Ever wondered what a fly’s worst nightmare might be? No, nor have I, but I bet it looks something like Venus flytraps catching their dinner.

 

Despite their name, and the fact that they look like something from another planet, wild Venus fly traps (Dionaea muscipula) are actually only found in the wetlands that lie within a hundred-mile radius of Wilmington, North Carolina, Planet Earth.

 

And another thing - they don’t just eat flies. As long as its prey is roughly the right size, and touches two of its hairs within twenty seconds, then the carnivorous plant’s jaw-like leaves will snap shut on any insect or spider that comes its way.

 

If the meal is too small and is able to escape then the leaf opens up again within a few hours. But if dinner continues to struggle, the lobes close even further until the outer edges have sealed to form something akin to a stomach. Here, glands in the lobes secrete enzymes that break the dinner down into a fluid that the flytrap can then digest.

 

Ten days after dining on the soup in their fly, the trap pops open to reveal nothing but a dried out husk.  Despite the poor soil beneath it, the plant has just obtained all the nitrogen it needs.

 

As it can take two to three weeks for a new leaf to develop into a fully-formed trap, cameraman Tim Shepherd used time-lapse photography to bring the sequence to life. But there is nothing speeded up about the traps shutting on their prey. That takes just a fraction of a second.

What's up with the sound effects, seriously, I was expecting one of the flies to do the "Help me, help me" in a little voice. Seriously, the burp when the plant opens? Really??

I love the quality of BBC footage, especially the nature shots, but why do they have to foley in all the sound effects? It takes away from the production and overall quality of the production. I can understand if it was originally done for a kids segment or, but it's just insulting my intelligence otherwise.

You can't easily embed a YouTube video that has embedding disabled. There are ways to download that video and re-upload it, but that defeats the spirit in which the video was first posted (in this case, officially by the BBC).

I did get an explanation why embedding was disabled from the source, and though I disagree with the logic, it is what it is. :)

Still, it's a very neat video.

How does one go about embedding a video when the YouTube code says "Embedding disabled by request"? Is there a way to bypass that restriction, or was the limitation added later after the Queue submitter had obtained the code?
