A Mote scientist received an unidentified floating object (U-FL-O?) last week. It was a squid found at the surface by a sharp-eyed fishing captain southwest of Key West last Tuesday. The story made the news and now there are some updates. There is still a chance it is a new species but all the major characteristics point towards Asperoteuthis acanthoderma.
A. acanthoderma reaches a rather large size. The largest specimen known has a mantle length of 78 cm and long, slender tentacles. In one squid (45 cm ML) the tentacles were over 12 times longer than the mantle (i.e., about 5.5 m) (Tsuchiya and Okutani, 1993). The most distinctive feature of this species is the presence of very small, pointed cartilagenous tubercules over the surface of the head, mantle and arms.
The really interesting thing is that if this is A. acanthoderma, then it may be the first time it has been documented in the Atlantic Ocean. Up until now, all specimens have been found deep in the Pacific. So where has this one been hiding? How did it get here? Many mysteries remain.
In the tradition of Internet adages, I’d like to add another. In any discussion of sea life, no matter how rare, strange or disgusting, some knucklehead will always ask how well it goes with lemon or butter. I am calling this Gorton’s Law.
Now the more compelling question is to ask why this happens. Why do so many people consider the sea to be a smorgasbord? What difference is there between animals in the ocean and ones on land? For many, I suppose there is none. For example, on a swamp tour in Louisiana, our guide was kind enough to remind us that in his great state, if it bleeds, they eat it. However, Sylvia Earl, in her book Sea Change
, makes the point that we often eat higher up on the oceanic food chain than we do on the terrestrial one. She equates eating tuna with eating bushmeat. But it is true that many cultures do not eat large carnivores. Is this just because lions, tigers and bears are comparatively rare in the environment? Is that just because we have already extirpated them in our past? Obviously, it is certainly more dangerous to tangle with them than a herbivore. And perhaps that is the key. Even the fiercest of oceanic predators are manageable once landed. It can be a struggle to get a grouper on board, but once on deck it doesn’t take much to subdue it. So maybe it’s just a matter of buoyancy.
Many who would recognize the absurdity of a plan to sustain large and growing numbers of people by hunting and gathering from the land buffalol, deer, wild birds, rabbits, squirrels, roots, and berries seem to disengage their power of reason when it comes to the sea, apparently believing, somehow, that ocean systems are fundamentally different from those on the land, that they can year after year yield huge, comercially viable takes of wild-caught organisms and rebound indefinitely.

I don’t talk too much about my day job (seatrek.org) here on my personal site*, but I get to do some pretty neat things and work with some really great people. And today, CBS’ The Early Show did a segment on virtual fieldtrips that featured us. You can’t see me (I’m the one behind the camera) but you can see our studios at Mote Marine Laboratory.
Virtual Field Trips Take Off
Thanks to virtual field trips, students can visit far-away places without ever leaving the classroom. Susan McGinnis reports that the idea is catching on in many schools.
If you have any questions about videoconferencing or would like to schedule a program, let us know.
The Great Backyard Bird Count starts today and runs through this weekend, February 16-19, 2007.
The Great Backyard Bird Count is an annual four-day event that engages bird watchers of all ages in counting birds to create a real-time snapshot of where the birds are across the continent. Anyone can participate, from beginning bird watchers to experts. It takes as little as 15 minutes. It’s free, fun, and easy—and it helps the birds.

The Alliance for Science is running an essay contest for high school students with the topic: Why would I want my doctor to have studied evolution? Essays are due March 31, 2007. First place prize of $300 to the winning student. And the teacher of the first place student gets $250 to “purchase laboratory equipment, supplies, or other teaching materials.”
On this day in 1809, a couple of significant figures were born: Charles Darwin and Abraham Lincoln. And even though it’s still a couple years off, it’s not to early too start planning for their 200th Birthday celebration. It will also be the 150th Anniversary of the publication of Darwin’s On The Origin of Species.
The objective of Darwin Day Celebration is to encourage existing institutions worldwide, such as municipalities, public and private schools, colleges and universities, libraries, museums, churches, private organizations and individuals to celebrate Science and Humanity every year, on, or near, February 12, Darwin’s birthday!
There is also an effort afoot to build a recreation of Darwin’s famous brig, the HMS Beagle. His trip around the Galapagos while onboard provided much of the inspiration for his theory of evolution.
[T]he Beagle Project…aim[s] to provide the most compelling events of Charles Darwin’s 2009 anniversary by building a sailing replica of HMS Beagle and sailing in Darwin’s wake. The build and Beagle’s arrival in the Galapagos in 2009 will be two of the most striking, iconic media events of the 2009 celebrations, aimed at firing the scientific imaginations of a new generation and celebrating the life and work of Charles Darwin, one of the greatest biologists ever.

A couple of weeks ago the world got to see stunning video of a rare deep sea frill shark. Another bizarre looking customer is the goblin shark (Mitsukurina owstoni). You can check out some amazing photos and videos of a live goblin shark at this website:
We eagerly await to see if the fine folks from Pink Tentacle can help with a translation. In the meantime, here is Google Translates robotic effort.
UPDATE: According to the Underwater Times, the shark did not survive for long.
A goblin shark — a rarely seen species often called a “living fossil” — was caught alive in Tokyo Bay but died after being put on display, an aquarium said.
The grey, long-nosed shark was caught in fishermen’s nets around 150 to 200 metres (500 to 650 feet) deep. It was discovered by officials of the Tokyo Sea Life Park when they took a boat with local fishermen on January 25.
But the shark died on the morning of January 27.
The Reuters report repeats the misconception that these deep sea creatures die primarily because of a sudden pressure change. Deep sea animals have bodies composed mostly of water, with no gas pockets. Because liquids are virtually incompressible, these animals seem to suffer little pressure-induced effects from dramatic depth changes. It’s far more likely that the change in temperature is more stressful (from 4°C to ~30°C).

OceansLive.org is a NOAA outreach program affiliated with Bob Ballard and company. It’s difficult linking directly to their content because it’s partly tied up in Flash. But one of the videos worth noting is under their ARCHIVED VIDEO section. It is a dissection of a dead Laysan Albatross chick on the Kure Atoll. It’s a pretty graphic depiction of the problem of plastic in our oceans. The parents mistake the floating debris for food items and instinctively regurgitate them to the young. The chicks can become so impacted that they die of malnutrition. Or in the case of the bird in the video, the plastic punctured the stomach and acid burned the liver and blackened the lungs.
It is remarkable and sad how much garbage the researchers pull from one dead chick. The other absurdity is just how remote Kure Atoll is from the rest of civilization. It’s literally in the middle of nowhere, but still affected by our conspicuous consumption.
