Raimondi had recently found himself undergoing an unexpected and not entirely desirable career shift: He had been thrust into the role of sea star detective. Though he is a marine biologist who divides his time between analyzing data and conducting research trips along the Pacific Coast, Raimondi is not entirely ill suited to the part. There is a private-investigator quality to his round, inquiring face, active eyes, and urgent, impatient voice.
Leafy, verdant Elysia chlorotica (the Eastern Emerald Elysia) is a sea slug with a secret: they photosynthesize. These marauding mollusks slurp up chloroplasts from their favorite algal snack, Vaucheria litorea, incorporating them into their own digestive cells and putting them to work soaking up sunshine (and, incidentally, acquiring a healthy green glow). But how? [more inside]
Scientists find translucent fish in a wedge of water hidden under 740 meters of ice, 850 kilometers from sunlight
Researchers sneak up on sleeping sperm whales (.mpg video, hosted by Current Biology.) Matt Kaplan, writing in Nature, summarizes a 2008 article in Current Biology: "An accidental encounter with a pod of sleeping sperm whales has opened researchers’ eyes to some unknown sleep behaviours of these giant sea creatures . . . A team led by Luke Rendell at the University of St Andrew’s, UK, were monitoring calls and behaviour in sperm whales (Physeter macrocephalus) off the northern Chile coast when they accidentally drifted into the middle of a pod of whales hanging vertically in the water, their noses poking out of the surface. At least two of the whales were facing the boat, but not a single animal responded." [more inside]
I am a giant squid. I swam up from the briny ocean depths. I have a computer, with a specially-modified tentacle-friendly interface. I have a fast internet connection. I seek to learn about humans and about the world. I have read much on the internet. Yet still, I have many unanswered questions. And you must have questions of me. We have much to learn from one another. To this end, I have developed the assortment of quizzes, games and activities you find before you. They form part of my ongoing campaign to facilitate improved human-squid relations. Try them out, you will most certainly learn something about squid.
Scientists at the Auckland Museum will be performing a necropsy of a great white Shark between 11am and 1pm New Zealand time on Thursday. Though they will be examining the contents of its gut, they will also, among other things, look at its sex organs (female) and jaw. The necropsy will be viewable on the web from 2pm NZ time (when's that?). [more inside]
Hundreds of New Reef Creatures Found in Australia. Hundreds of new marine creatures have been discovered in three Australian reefs by CReefs, a census of coral reefs which is part of the Census of Marine Life, a ten-year initiative to assess global ocean diversity.
Dolphin intelligence is under fire, but are these arguments over brain size relevant in the face of overwhelming behavioral evidence? Dolphins have been known to display almost all of the qualities which we would consider uniquely human, qualities that we would consider a mark of ‘higher’ intelligence. They are tool users, they are highly creative (perhaps even artistic), they enjoy recreational and social activities, from surfing (either on waves or around the prow of boats) to sex, and they have proven time and time again that they are self-aware. They’ve also formed symbiotic relationships with fisherman, and recent reports suggest that dolphins even have names for each other. But perhaps Douglas Adams said it best in the Hitchhiker’s Guide: “Man had always assumed that he was more intelligent than dolphins because he had achieved so much... the wheel, New York, wars, and so on, whilst all the dolphins had ever done was muck about in the water having a good time. But conversely the dolphins believed themselves to be more intelligent than man for precisely the same reasons.”
The Starving Ocean : A large collection of articles by Debbie MacKenzie on the death of the ocean. The idea is that removing most of the fish from the sea might be sort of bad for the marine ecosystem as a whole. Her writing style is a bit kooky, but she has been right on some points (ie. the Grey Seal thing). Oh, and fishing is also responsible for the rise of atmospheric carbon dioxide.
