Why I don’t go into the water: Jellyfish with both “medusa” and “gigantica” in their Latin names should be avoided on principle

I’ve seen a lot of pics of giant Jellyfish lately, mostly these Nomura’s jellyfish who inhabit the Sea of Japan like Godzilla’s own colon polyps. I fear them, of course, but I admit to cheering for them as they sank a Japanese trawler last year…nobody was hurt.

But looking up info on oarfish, I came across Mark Benfield‘s work at Louisiana State University. He’s working with oil and gas industry ROVs — submersible robots — to study wildlife. Hey, its the least the industry could do. No, seriously, the very least.

Last spring, Benfield published the first account of Stygiomedusa gigantea, a giant jellyfish, in the Gulf of Mexico. They aren’t trawler-eating big, but they are still fairly huge. They are apparently fond of grabbing onto underwater structures — such as pipelines or oil rigs — to use as a base for feeding. See, the oil industry is providing a valuable service!

Discover Magazine interviewed Benfield last month. Cool, shudder-inducing vid:

Why I don’t go into the water…Reason #1,768

I could not be in the same ocean as this creature and not be gripped by paralyzing fear (not to mention paralyzing tentacles!). Behold, a great big jelly, the likes of which are not meant to be seen.

As the Discovery News reports, monster jellyfish like this are becoming more common as fish populations dwindle.

They say climate change could also cause jellyfish populations to grow. The team believes that for the first time, water conditions could lead to what they call a “jellyfish stable state,” in which jellyfish rule the oceans.

The combination of overfishing and high levels of nutrients in the water has been linked to jellyfish blooms. Nitrogen and phosphorous in run-off cause red phytoplankton blooms, which create low-oxygen dead zones where jellyfish survive, but fish can’t, researchers said.

Just great. We’re doomed.
