Thanks in large part to this blog and to professional connections in the Sea Grant network, I had the amazing privilege of being a guest naturalist the April 3rd performance of the the nationally syndicated radio show A Prairie Home Companion. The show was broadcast live from the Paramount Theater in Seattle on April 3rd. I was referred as a potential guest for the show on Wednesday March 31, had a conversation with Garrison Keillor (host of Prairie Home Companion) on April Fools Day (the voice make and date prompted a double take) and on Saturday enjoyed a casual conversation about marine life in front of 4000 people and 4,000,000 listeners.
It was a fabulous feeling and an honor. I have to admit though… I couldn’t help but be a bit nervous. In the past, my musical alter-ego has been on stages big and small, singing everything from country to opera. This was different. I was going to be talking about something I loved, both personally and professionally, with a master of wit and improvisation… with no real preparation. Eek!
However, after watching everyone else in the show, my nerves eased and it felt natural once the time came to step up to the mic. Oddly enough, the curtain call felt even more comfortable, when I could join in a chorus of Johnny Cash’s I Still Miss Someone.
Orcas, octopuses and geoducks were the sea life we spoke most about on the show. Since a geoduck (Panopea generosa) was my companion on the show, I’ll give them a bit of attention here.
You can’t help but be immediately struck by the obscene enormity of its neck and its resemblance to something you might see in the pasture. Yet, there’s so much more to this Salish Sea icon.
This clam’s name originated from the Nisqually tribe in South Puget Sound as “gweduc”, meaning “dig deep”. As Europeans transcribed the name, they manged to go from gweduc to gooeyduck or goeduck to geoduck. Gee-o-duck? No matter how it’s written, Salish Sea residents still call them by their proper name, while those outside our region tend to be confounded by the matter.
The geoduck can be found from Kodiak, Alaska to Newport Bay, California, but it’s probably best known from the Salish Sea. The geoduck wins the title of “world’s largest burrowing clam”, averaging over 2 pounds but sometimes weighing 10 pounds or more with necks over a yard in length. They are also among the oldest animals in the world, living in excess of 140 years
A geoduck’s long neck actually consists of two hose-like siphons. The incurrent siphon brings plankton and detritus rich water to the body, 3 or 4 feet down into the muck. The water passes across the gills which extract oxygen but also use mucus to glean food from the water before it makes the long journey through the excurrent siphon, back up out of the sediments.
Of course, you’d never know any of this from what you see on the beach. Only the tip of their siphons extends above the seafloor, though it may be several inches of the tip.
Digging a duck is a challenge since they’re so deep and so low in the intertidal. You have to race against the tide to dig deep before the tide overtakes your hole.
If you do manage to get one (from the beach or the market), you’re in for a treat. There’s a lot of meat to a geoduck, and amazingly enough, the meat is quite sweet. Tenderize it a bit, slice it up, role it and flour and toss it in a frying pan. Mmmmm. You can find several recipes and a everything else you could want to know about geoducks in Field Guide to the Geoduck by David Gordon, who is now Washington Sea Grant’s science writer.
You may also enjoy the lyrics and sheet music of Dig a Duck a Day. More recently, a Canadian band called the Bottomfeeders and a Seattle area Band called the Whateverly Brothers both have great geoduck songs. You can here the Bottomfeeders and Dig a Duck a Day on the fabulous duckumentary 3 Feet Under: Digging Deep for the Geoduck (trailer). So much great stuff about geoducks! Enjoy and may the force be with you if you hope to dig a duck a day. JEff
