Now that we’ve got 45+ followers, I think it’s time to start the first art contest. My original plan was for the winner to receive a print or t-shirt of their design, but since funds are limited, we may only be able to offer recognition (and possibly the prize in the future). With that in mind, here are the guidelines:
Can be any medium (digital, paint, pencil, etc.)
Must include at least 1 jellyfish image.
Must be submitted by April 6th at midnight.
Also, please let me know if you’re participating, just so I can know how many to expect. Thank you!
Don’t take it too seriously, and have fun! I’m really looking forward to seeing everyone’s submissions…
"The fluid dynamics of swimming jellyfish have provided a plausible mechanism for a once-wild notion: that marine animals, hidden from sight and ignored by geophysicists, may stir Earth’s oceans with as much force as its wind and tides.
Called induced fluid drift, it involves the tendency of liquid to “stick” to a body as it moves through water — and a little bit of drift could add up quickly on a global scale.
“The mere act of swimming implies that some water travels with the swimmer,” said CalTech engineer Kakani Katija, co-author of the study in Nature Wednesday. “Drift applies to all animals, to anything with a body.”
That the mere motion of animals could play a profound role in water-column commingling was once considered absurd. The sea would surely absorb the force of a flapping fin, to say nothing of a phytoplankton’s flagellae. It was a basic principle of friction, applied to water.”
I just wanted to say ‘thank you’ to all my followers. The blog is doing better than I thought it would! I’d love it if you guys submitted some things. Also, we should be starting the art contest soon, just waiting for a few more followers.
Below: The deadly, venomous Box Jellyfish. (Did you know that the venom from a Sea Wasp or Box Jellyfish is enough to kill up to 60 adults?)
"Sea Wasps or box jellies, are not aggressive. They don’t have to be. For jellyfish, they are pretty fast swimmers (up to 5mph), dangling their long tentacles in the surf behind them until something, usually a fish, gets caught in their practically invisible tentacles. That’s where all their nematocysts are located. (Most people who have been stung are Aussies who were swimming in the surf along with the jellies and never even saw the tentacles.) The poison is used to kill their prey as close to "instant" as possible in order to prevent a struggling victim from thrashing their delicate tissues. Makes sense. Then they can take their time devouring their meal without risking injury to themselves." - Extreme Science
"The body of a sea wasp can weight as much as 2 kg. The tentacles are armed with up to 5,000 nematocysts, or stinging cells. Certain chemicals on the surface of fish, shellfish and humans activate these. Contact with only 3 m of tentacles may be fatal for an adult. There are many (about 70) reported deaths that have occurred in northern Australia between November and April.” - Poisonous Plants and Animals
Here is a simple, 55 second video describing nematocysts and exactly how they work. Copy and paste, its worth it.:
maybe you could give people around 3 weeks ?
and 3 months for a big one ?
haha i dont know... do as you please. (:
Yeahhh, that should work. I didn’t think about doing a ‘big’ one, but now that I think about it, it sounds pretty neat. I seriously need to work on getting more followers at the moment, b/c all I want to do is start the contest. ;)
If anyone has existing jellyfish art that you will not be using for the contest, feel free to submit as a discussion topic or if you’d like feedback!
