Friday Fluff #4: For when enough is enough

Enough is officially z'nuff and I pronounce this week over. It's been a long and pretty sad week as, amidst the national pain following the shooting in Orlando, the field of ecology lost a literally towering figure with the passing of Bob Paine. There's been a lot of opportunity to reflect on his contributions to the field, and I've spent time reading some of his interviews (including one I participated in) as well as pieces others have written about him. I think the best thing to do is to take some time to marvel at the ridiculously elegant nonsense that nature has come up with, and then get back to work.

With that in mind, here is some ridiculously elegant nonsense that is perfect.

Thing the first:

When mollusks collide, arthropods win.

Thing the second:

I meant to post this months ago when David Bowie died. I think the unintentional wait was worth it, because the content has kept growing. I have a soft spot for the sailor version of Onchodoris muricata...

Thing the third:

I also loved this recent video from Emily Graslie at the Field Museum. She meets with the Invert Collections Manager, Jochen Gerber, who pulls some of the coolest snails out to talk about with her. I know they are the coolest because they are my favorites too, including the Snail of Ice and Fire, Aviator Snails, and Conchologist's Conch. I also got some inspiration for a future Species species of the Week week...but more on that later.

PS!
I'm now on Twitter, because I heard it was a dying medium - so I think that makes me hipster? Follow @rahrahradula

Friday Fluff #3: For When Enough is Enough

Thing the first: Thar Be Snail Ogres!

Does this look like a beautiful lady to you?
What is the DEAL with sailors?!

I'm sharing a cool Echinoblog post I found in the only way anyone finds anything these days - Twitter. In time for halloween, Christopher Mah describes the mythology of and actual inspiration for several Japanese monsters. This being a Mollusc-centric blog, I will feature the Snail Ogre, Sazae-oni, here, which somehow transfigures into a drowning woman, or something convincingly enough like it to attract sailors, who become the snail's next meal. The real snail this legend is based off of is the horned turban snail (Turbo cornutus1). This image also reminds me of Aku.

There are a number of other monsters on there that are worth checking out and attempting at Halloween costumes, such as the Samurai crab, and/or Stephen Hawking, and the internet darling of the year, the dumbo squid.

Thing the second: Killer Whale Espionage

Because you know you want a giant orca photo...L94 and her baby nursing in BROAD DAYLIGHT! She's not even using a blanket, how indecent! Photo credit: NOAA Fisheries, Vancouver Aquarium

The world is all atwitter, quite literally, about the use of drones in research of the Southern Resident Killer Whales. I've blabbed about some of the recent population growth of this group (here), and there have been even more calves born this year. NOAA just released a video podcast show-and-tell of some recent photos obtained via hexacopter. The contraption, which is strapped to two pool noodles for flotation, flies above the whales to get good pictures of them without disturbing them. They can ID and measure the whales to track growth rates.

Surveillance photos indicate that the babies keep on coming (welcome, Baby L-122!), and the hexacopter provides insight into family life of the growing pods. This year has been a good year for the whales, lots of babies and seemingly well-fed whales. Hopefully that trend lasts.

Thing the third: See Slug Day!

Yesterday was Sea Slug Day! I don't really even have that much to say about it, except that it's worth trolling #SeaSlugDay for the photos, but don't say I didn't warn you that it was a black hole of a time suck! You sort of start to wonder if this group isn't really just an alien race living among us. Or we are a prison planet for all of some other planet's criminals: what with kleptoplasty, and kleptocnidae - they're evidently really just into stealing things, evidently.

Super cutie: O. muricata on E. pilosa

As an undergraduate, I did research on what is the least colorful species in the most colorful group of organisms in the world - Onchidoris muricata. That doesn't mean it wasn't charismatic! I was researching whether this tiny white blob, which you would be well within your rights to assume was some previous beach walker's snot rocker, was interested in eating an invasive bryozoan(2), in the Gulf of Maine. The bryozoan, Membranipora membranacea, was super abundant there, growing all over rocks and kelps. We gave the snot rocket nudibranch a choice between it's presumed preferred food (a native bryo Electra pilosa) and the new bryozoan (which they are probably serving at that gastro street-food from around the world fad place down the street from me), and found that the slug preferred to eat the fancy new food, and could eat it faster.

This was back in 2004, when we wondered, what could this mean for future slugs? Just this year, people are starting to think about whether invasive species are good food for native species - they could be right? Well it turns out that in a lot of cases, they are often beneficial as a supplement to a balanced diet, so they don't harm native species. But on their own, they aren't as good as the diet the predator evolved to eat. So, no you can't have Doritos for breakfast, lunch, AND dinner.

Phew, for Friday fluff, that really was some academic non-sense I just prattled on about(3)! Here's a palate-cleansing video... 

Check out this video I found in my archives. Marney Pratt, my Advisor on the project, grew some bryozoans onto a microscopes slide, and fed them a red algae so that they would show up clearly against the background: the red dots you see are individual bryozoans, called zooids. The big white blob is a single Onchidoris, and you're looking at it from beneath, through the side of a tank and the glass slide. Marney filmed this time lapse of the slug eating a single zooid. If you watch closely, there is one zooid that gets slurped out of its little house toward the bottom right. This is sort of like how an oyster drill (predatory snail) consuming an oyster in that "sucks-his-guts-out" is still an applicable description.

SEE! I told you they were charismatic!

Friday Fluff #2: For When Enough is Enough

Thing the First: Blue Tide hits Washington Coasts

What a freaking mess! Someone should do something about this! Photo: Tiffany Boothe, Seaside Aquarium

This is old news now, but I was resisting putting it on the blog for a long time. Really strong westerly winds have pushed literal heaps of everyone's favorite blue tautonomical cnidarian onto coastal beaches in Washington and Oregon over the last month. Is it called a "blue tide"? I don't know. Should it be? Maybe, "blue tide" is kind of redundant. In any case, yes, Velella velella has become a victim of its own ingenious dispersal ability (1), and create just endless fields of rotting blue mesoglea (2). The most stunning statistic coming out of this whole ordeal is that only 50% of science journalists know how to capitalize latin names. Editorial Fails include: USA Today, The Weather Channel, KOMO news (local, and having the opposite problem as the others). CNN did get it right, but then lost points for referring to "something fishy going on in Washington" which is as original as it is semantically correct - not at all. Anyway, there's a lot of cool pictures. This isn't really something anyone is concerned about, they aren't a huge health hazard, or an endangered species, and this isn't some major environmental catastrophe. This happens from time to time to these guys, and could happen more frequently as climate change alters the frequency of certain weather patterns.

Thing the Second: Pretty Subtidal Seattle OR Pretty (Subtitle: Seattle)

If you think it's beautiful above the waterline in Seattle this time of year (and you're right, it's ridiculous), check out this video my very talented friend Eliza Heery made celebrating our green waters! Eliza does what she calls Urban Marine Ecology, exploring how marine ecosystems function so closely to an extremely dense urban environment.

Thing the Third: Foaming with rage and bruised all over the chest

Just some old crummy boat...wait it looks familiar! Photo: Richard Rodriguez, Bitter End Blog

The most faithful molluscophiles among you will remember my reference to John Steinbeck's (and Ed Ricketts', cough cough) description of the infuriating intractability of the the Sally Lightfoot Crab (Grapsus grapsus, naturally). The vignette was from the Log from the Sea of Cortez, detailing a whimsical collecting trip the likes of which will never occur again. Some have tried, like really tried, down to the brand of beer, which was evidently a crucial aspect of the trip. But I suspect we won't get narrative like Steinbeck out of it(3). Anyway, the point is that the boat Steinbeck and Ricketts took, the Western Flyer, is still in existence, sort of, in Port Townsend, WA. It's sunk more than once, and certainly has some tragedy in its history, but the new owner hopes to restore it and potentially return it to Monterey - hopefully not as a restaurant...A book about the post-Steinbeck/Ricketts history of the Western Flyer recently came out - in time for father's day, score.

Happy weekend!

Friday Fluff: For when enough is enough.

It's after 4 on Friday, and I just spent a few hours trying to teach myself sql. Soooo ... brain. Because. But three easy pieces did cross into my field of view recently, and so:

1. Even extinct cone snails get all the attention!

Cone snails get a disproportionate amount of attention, mostly, I suppose because they are so diverse. Admittedly, they have some cool ecology, but nonetheless, those of us who don't work on them (or maybe just me) are sometimes a bit jealous of all the hubbub about a single group. So it was unsurprising when I saw this post from the Smithsonian blog about how entrancing even extinct cone snails are. A researcher from San Jose State University used UV light to show the color patterns on fossilized cone snail shells. Some of the pigmentation was no longer visible to the naked eye, but using this technique, this guy identified more than 10 new species! I feel like there should be some comment here about inspiration coming from the strangest places - like raves and velvet posters. Here's the original paper, with more cool photos.

how UV light can be used to reveal historic coloration of fossil cone snail shells

2. Between a rock and a limpet radula

Well, Rah rah radula indeed! In fact, we had better hail the radula or it will come for us, and we will not come out on top. Engineers at the University of Portsmouth (also in Science Daily) have proclaimed that limpet teeth are made of the strongest naturally-occurring material known to man. Here, "strongest" refers to highest tensile strength and has nothing to do with towing a 767. For those of you who still think terrestrial systems have anything to offer ("But, but, what about spiders?") it turns out these fangs have toppled spider silk as the champion of natural material strength. 

No, this picture does need to be this big. If the last post on attack snails wasn't enough to give you nightmares, this should be. Image from the University of Portsmouth. 

All of that from this:

Patella vulgata, the common limpet. Just think about how
strong teeth would be from an UNcommon limpet.

3. Beauty abounds thanks to El Nino!

California faces drought unprecedented in recorded history and John Steinbeck wishes he were alive to document it. But Californians have something positive to look forward to - population booms of this beautiful slug, Okenia rosacea, which benefits from warmer temperatures. The Hopkins rose nudibranch is being spotted much further north than is usual. More from Science Daily and the primary literature.
