Sea Slugs
I thought this was interesting and wanted to share it Smile

A green sea slug appears to be part animal, part plant. It's the first critter discovered to produce the plant pigment chlorophyll.

The sneaky slugs seem to have stolen the genes that enable this skill from algae that they've eaten. With their contraband genes, the slugs can carry out [url]photosynthesis[/url] - the process plants use to convert sunlight into energy.

"They can make their energy-containing molecules without having to eat anything," said Sidney Pierce, a biologist at the University of South Florida in Tampa.

Pierce has been studying the [url]unique creatures[/url], officially called Elysia chlorotica, for about 20 years. He presented his most recent findings Jan. 7 at the annual meeting of the Society for Integrative and Comparative Biology in Seattle. The finding was first reported by Science News.

"This is the first time that multicellar animals have been able to produce chlorophyll," Pierce told LiveScience.

The sea slugs live in salt marshes in New England and Canada. In addition to burglarizing the genes needed to make the green pigment chlorophyll, the slugs also steal tiny cell parts called chloroplasts, which they use to conduct photosynthesis. The chloroplasts use the chlorophyl to convert sunlight into energy, just as plants do, eliminating the need to eat food to gain energy.

"We collect them and we keep them in aquaria for months," Pierce said. "As long as we shine a light on them for 12 hours a day, they can survive [without food]."

The researchers used a radioactive tracer to be sure that the slugs are actually producing the chlorophyll themselves, as opposed to just stealing the ready-made pigment from algae. In fact, the slugs incorporate the genetic material so well, they pass it on to further generations of slugs.

The babies of thieving slugs retain the ability to produce their own chlorophyll, though they can't carry out photosynthesis until they've eaten enough algae to steal the necessary chloroplasts, which they can't yet produce on their own.

The slugs accomplishment is quite a feat, and scientists aren't yet sure how the animals actually appropriate the genes they need.

"It certainly is possible that DNA from one species can get into another species, as these slugs have clearly shown," Pierce said. "But the mechanisms are still unknown."

I don't know why but this site won't allow me to post a picture from photobucket. I don't usually have any problems posting pictures from photobucket so it doesn't make sense to me to not be able to now Sad

So I did the next best thing and made a picture clickable from the Live Science Website Smile


EDIT: if the other URL's don't work please don't ask me why `~`

Sinny: Thanks for posting it, even if the URLs don't work. Fascinating!
That's awesome. Loved the pic.

Thanks for the story Sinny.
's 'mazing!
I'll drink to that. Or anything else for that matter.
I'm glad you guys liked it....I was so fascinated by it and found it so interesting I just couldn't resiust.

Here's the sites that weren't clickable if anyone is interested. Most have nothing really to do with the sea slug except the last url I posted here which is where I finally got the picture from, I think that's where.




This s pretty coolSinny
