Random Quote
There are many extraordinary tales from antiquity, including women with snakes for hair, creatures whose gaze turns you to stone, creatures with equine bodies and human torsos, many accounts of people rising from the dead, lots of tales of magic, and numerous accounts of physical encounters with fantastic beings. Ancient people were a superstitious, scientifically primitive lot, and believed in many things that today we know are silly. I find it bizarre that so many people see nothing suspicious about the extraordinary or supernatural claims of the bible, yet don't hesitate to express disbelief in equally well documented claims of minotaurs, basilisks, and wizards.

weird, because most of them are aposematically colored in order to engender the exact opposite reaction from potential predators.
most of them are in fact, toxic to most predators (Navanax - another kind of nudibranch more closely related to bubble snails - excluded).

Now if we can only get hermaphroditic marriage recognized...
In Massachusetts and California it is. In striking down the marriage restrictions they did, both state Supreme Courts made it possible for people of intermediate sexes, and transgender folks as well, to marry.
Posted by: Avekid | May 15, 2008 6:42 PM
Those are some gorgeous specimens. Wow!
MAJeff:
Cool. I must not have read the stuff on the CA decision very carefully because I missed its recognition of transgendered folks too. Finally, the "T" is back in "GLBT". That really is a groundbreaking decision!
Posted by: TheWireMonkey | May 15, 2008 6:42 PM
@MAJeff
Can you imagine how fabulous a nudibranch wedding would be!
Actually, Chromodoris does sort of look like a bridesmaid dress I was forced to wear once...

MAJeff:
Cool. I must not have read the stuff on the CA decision very carefully because I missed its recognition of transgendered folks too. Finally, the "T" is back in "GLBT". That really is a groundbreaking decision!
They didn't name T people in the decision. They struck down gender restrictions. The redistribution to Trans folks took place without a specific legal recognition of them.
As I said in the thread below, the Court based its ruling on the right of the individual to choose a marriage partner, striking down laws that set gender restrictions in place.
That's another reason I think the CA decision is stronger than MAs. In the argument itself, it located the right in the individual and said that gender was irrelevant.
Does that make sense?

This must be the first time I've every seen a photo gallery of nudibranchs without one of them being a Spanish Dancer.

What? It's a link. He's not hotlinking the photo, y'know, he stored a copy on his own server--it's just that the photo is also a link. Do you object to the deep link? Is this some strange new rule of etiquette I wasn't previously aware of?

Hate to throw cold water, but photographically these things are oversharpened and oversaturated. The photographer used Photoshop with an unusually heavy hand: he should be called the Thomas Kincade of nature photography.

you are right to suspect such:
http://oceanexplorer.noaa.gov/explorations/05deepcorals/background/chemical_ecology/ecology.html
http://www.mrd.ucsd.edu/jf/
(there is a TON of work on the biomedical value of chemicals from marine invertebrates and algae done at Scripps Insitute, btw.)
Specifically though, it appears that the largest value of nudibranchs has been that they tend to concentrate the toxins of the things they feed on, which has lead to discoveries of the value of many chemicals from sponges for example.

MAJeff:
I only skimmed the comments in the thread below and I must have missed that one. Having gone back to it, now it definitely makes sense. Thanks. =)
I like the shift of emphasis to the right to choose. It makes sense, but it's still incredible that that kind of decision passed. That really is something to celebrate.

completly off topic but found no better place:
The Agenda (nice show on TV Ontario) had a nice discussion about scienctific research under attack
(http://www.tvo.org/cfmx/tvoorg/theagenda/index.cfm?page_id=3&action=blog&subaction=viewPost&post_id=7491&blog_id=323)
From the blog:
The proposal, led by Prof. Brian Alters and titled " Detrimental Effects of Popularizing Anti-Evolutions's "Intelligent Design Theory" on Canadian Students, Teachers, Parents, Administrators and Policymakers," was denied funding by the Social Sciences and Humanities Research Council.
What was surprising, was the reason for the denial. In a letter, the SSHRC responded:
"The committee found that the candidates were qualified. However, it judged the proposal did not adequately substantiate the premise that the popularizing of Intelligent Design Theory had detrimental effects on Canadian students, teachers, parents and policy makers. Nor did the committee consider that there was adequate justification for the assumption in the proposal that the theory of Evolution, and not Intelligent Design theory, was correct. It was not convinced, therefore, that research based on these assumptions would yield objective results. In addition, the committee found that the research plans were insufficiently elaborated to allow for an informed evaluation of their merit."
What do you think of this response and tonight's show?
not only in the US of A....

You're so flamboyant
The way you look
It gets you so much attention
Gorgeous. I saw some of these beasties in a video of my brother and sister-in-law's scuba diving off the coast of... the Philippines, I think. Called them "drag queen slugs".
Posted by: Bill | May 15, 2008 8:04 PM
Wow! At first glance, I thought the first piccie was a hand-painted tabletop miniature, maybe some kind of Tyrannid eater. The second one, Halgerda batangas, makes me think of shoggoths, and Flabellina exoptata looks like someone should be ecstatically shouting Ia! Ia PZ! Ia Shub-slimey!

Great Cthulhu! Such bizarre beauty! Some of those look like they'd be right at home in a Burgess Shale diorama...
Posted by: Chris | May 15, 2008 8:28 PM
It reminds me of the nudibranch I caught in Florida during a marine biology field trip. Unfortunately, the tank my professor set up to keep our specimens alive got clogged with sand overnight and every single specimen was dead when we came in the next morning. She was a decent lady, just terrible in the practical set up of an aquarium. Lesson learned. Kind of.

As long as slugs stay in the sea they are perfectly alright by me, but if they should venture, on their trails of slime, into my garden to dine - on my hostas, no less, I say DIE, DIE, DIE.

This has made my week. I love nudibranchs.
My partner and I frequently saw these Nembrotha last fall when diving in Malaysian Borneo. There are actually two color variations of the same species -- the one shown with green stripes, and another with green spots.
Posted by: SEF | May 15, 2008 9:21 PM
I came across some knitted nudibranches etc quite a while back:
http://www.etsy.com/shop.php?user_id=5162135
(and I'm so pathetic I kept the link).
Posted by: Bad | May 15, 2008 9:48 PM
God how I love these little critters.
Unfortunately, they are a real pain to keep alive and happy in captivity. They either have really picky, specific diets (and often of sponges or corals which would be very expensive) or are super sensitive to water quality, or, even barring all that, just don't live very long or reproduce very successfully in closed systems.
As is often the case, there are a few that can survive decently in captivity... and those are the notorious pest species like the Montipora eaters. :)
Posted by: Jams | May 15, 2008 10:02 PM
Slightly OT...
Ben Stein was on "The Hour", a CBC (Canadian sponsored) prime time "news" show tonight.
That's fine, except that the same show introduced Christopher Hitchens on the topic of his book "God Is Not Great", as being a particularly "controversial figure", while Stein was portrayed as a good man of conscious who, in spite of his relationship with Nixon, was a stand-up guy who's brought much needed light to the every-so-important theory of creationism. Kid gloves with the god guy, hell fire for the rationalist.
What a bunch of douches.
Wait, I mean... what a bunch of brainless Catholic douches (according to the host's advertised idiotic leaning). After all, we can generalize about these sorts of things.
Posted by: valor | May 15, 2008 10:10 PM
Am I the only one who got a weird "I've had that nightmare" sensation when they described how one of them eats algae alive and then farms them under its own skin?
Because that creeped me right the hell out.
Posted by: BMurray | May 15, 2008 10:19 PM
If you want your own nudibranch but don't want to keep up a tank, there are some wonderful knitting patterns here: http://www.etsy.com/shop.php?user_id=5162135§ion_id=5109482
Knitting's easy, so everyone should have all the nudibranchs they want in short order. Squid too. And jellyfish.

Bad: Ya, I know what you mean about closed water systems. At the Environmental center where I worked, I had an open system. I could keep things alive that the Skidaway Marine Institute couldn't. Sea jellies, Corals, You name it. I think our nudies were eating hydroids. But honestly, the worms were even cooler than the nudibranchs.

Posted by: Numad | May 16, 2008 4:11 AM
Jams,
I'm glad I'm not the only one who thinks The Hour is skewed in an ugly kind of way. At the end of the segment Ben Stein was all "all I want is the freedom to believe*!" and not a peep from The Host.
*And ask biology teachers questions about physics and the Holocaust.

i remember a few weeks ago reading a creationist comment that the platypus was too weird to have evolved......yes, you heard right, arguments from incredulity and general ignorance of biology rolled into one, just how does one define weird anyway? pathetic and demonstrative of the weakness of the creationist mind at understanding nature. Anyway hopefully that same person wont see these things or they might have ID meltdown.
looking at these is almost like tripping, its makes me think 'just how far can nature go??'.
amazing.

What's the deal with scubadivers and nudibranches? When my wife was diving in Australia last year, the divemaster would basically jizz everytime they saw a nudibranch. She didn't get it, either.

Here's a lovely video clip of a nudibranch species nicknamed the 'Spanish Dancer'.
This is the first nudibranch species I was ever introduced to as a child, so I guess I have a deep seated fondness for them.
When you watch the clip you'll see why they call it the Spanish Dancer.
The musical accompanyment also certainly helps to enhance the mood.
Just click on the link and enjoy.
