The Barnacle’s Fantastic Elastic Plastic Penis.
June 18, 2008
My buddy J. Matt studies sex allocation in hermaphroditic marine intertidal barnacles. In other words: How much should wet, salty, crusty she-males that live on the rocks invest in each of their naughty bits?
Barnacles are sessile (permanently fixed to a location, like a tree) crustaceans that maintain both male and female reproductive organs throughout the year, but they make their penises bigger in the fall when mating gets hot and heavy. But in addition to this seasonal change in the size of their trouser snake, barnacles can also sense features of their physical environment and use that information to change the dimensions of their John Thomas. If their neighborhood is crowded, they presumably needn’t invest much to fertilize their neighbors. When potential mates are distantly scattered, getting action can require quite a stretch. So barnacles make tiny tadgers when they’re rubbing against their consorts and lengthy dongs when their lovers are far.
The motion of the ocean can also affect how barnacles get it on. In protected coves, barnacle sex occurs unfettered by the destructive force of incoming waves. But when barnacles expose their Willies to crashing waves, they risk a fate I’d wish upon no functional male: breaking off the wang. Changing the length of the penis doesn’t necessarily mitigate this monstrous consequence, but making it sturdier at the base may help. Barnacles growing where the sex is ho-hum have a smaller diameter at the base of their schlong, while those growing where the sex is rough give it girth.

Some of the euphemisms for male sex organs were inspired by the Monty Python Song:
“Isn’t Awfully Nice to Have a Penis”
More Cephalopod

On my flight back from Seattle, the tv screen on the back of the seat in front of me kept replaying this video of Mark Bittman on NY TIMES. I have also heard from two people (independently) today that grilling octopus is worth a try.
I like Mark Bittman’s writing for the TIMES so far, and I am looking forward to reading this. As I stated in the last post, I am looking to reduce my intake of animals to balance out the last two weeks!
UPDATES:
Yep. My lifestyle makes it easy to drop meat pretty quick, based on his suggestions. Nothing new.
Also, Erik from MMMMMmmmmm DONUT… suggests this Bittman vid at TED. Its great.
UPDATE UPDATE: a good companion article to the vid
Seattle Eats and Cephalopod!
June 11, 2008
Just got back from the west coast, where I got to enjoy a variety of good food. One highlight was the restaurant Senor Moose in Ballard, WA which serves an amazing variety of authentic Mexican flavors. Agave margaritas, salsa verde, salsa puya, marinated chipotles, esquites (corn with epazote herbs and cream, YUM). I had slow simmered pork with zucchini and panela cheese.
I also had to hit up my favorite sushi place in Seattle, Shiro’s. I ate crustaceans, echinoderms, cephalopods, and fish. I had live sweet shrimp, which was brought out in two parts, the raw body, and the tempura fried head, antennae, and legs. This was the first time I ever ate those parts of the shrimp before. They were crispy and delicious.
I also had a tako salad. That was octopus tentacles with some yummy sprouts… and I can’t remember what else. Darn. I always go to Shiro’s when I am in Seattle. I sit at the bar and ask them to feed me whatever they want. Its always worked out well, I love that place.
I went a little overboard with eating out, but I really enjoyed a lot of it. I also went overboard with eating animal, and I am looking to get into eating a lot of vegetable matter now that late spring and summer produce are coming on the scene!
The Stained Glass Window of Life

Sometimes a good thing is hard to improve upon.
Hierarchical classification schemes for living things go way back in Western throught, evolving from Aristotle’s Scala Naturae to Carolus Linnaeus’ Systema Naturae in the 1700s. Later, phylogenetic trees were used to represent the evolutionary relationships among organisms and like many concepts in evolution, their use dates to Darwin’s time. In fact, Darwin scrawled something of a phylogenetic tree in his notebooks and published a tree in the Origin of Species. Read the rest of this entry »
Aquabats - Worms Make Dirt

Speaking of vermicomposting, this is my favorite song by the Aquabats, “Worms Make Dirt!” and here is a silly video with some sweet MS Paint and sock puppetry set to that music.
Of Worms, Oysters*, Home Brew, Birch Beer

I compost my food with worms, which I then feed to my pet box turtle. This week I got an invitation to post my worm bin on the map of vermicomposters around the world. Haven’t added a picture yet, but there are some good ones on there, like this one: http://flickr.com/photos/robindegrassi/2042100224/
If you compost with worms, check out these links: add yourself to the Vermicomposters.com map or join the Vermicomposters.com Ning ! These sites will also take you to more information on composting with worms… there’s a lot out there.
Right now I am composting with a species of worm that isn’t a very efficient composter. I’m not sure what species it is, but it is not the Eisenia fetida that is commonly used for composting. The worms are much larger, and they don’t reach the high densities that the E. fetida can achieve. We’ve also been having a problem with fruit flies in our bin (and in our house). The worm bin got moved to the porch, I recently split it into two bins, and now they are both sitting next to the bucket of Starbucks (R) coffee grounds that serve as growth media for Oyster* Mushrooms (currently on their third crop)! The Oyster mushrooms came from spores and media from Fungi Perfecti. We got an enokitake kit from them that sprouted a lovely crop in December.
This weekend I’ll be picking up home brew from my friends house. Steam Beer! The kit came from Karp’s Home Brew.
Also, I am thinking about making Birch/Sassafras Beer. I’m looking at recipes from the usual suspect: Stalking the Wild Asparagus by Euell Gibbons. Do you have a birch beer recipe to share? Leave a comment!
