The End of Fish - maybe it's finally time for an environmental accounting, cuz the 'bill' is coming due; stocks and flows, folks.

The amazing story of the coelacanth is one of the wonders of the living world that inspires marine biologists such myself. Coelacanths, part of the offshoot lineage of fishes known as "lobed finned ", are very different from typical "ray finned" fishes that you usually think of. Their bizarre lobed fins are thought to be an intermediate step between fish fins and amphibian legs. Scientists had known that these weird fish existed because of fossils for over a century, but we believed that they went extinct 65 million years ago... until a South African fisherman caught one in 1938.

Most people have heard about how rising CO2 levels are resulting in a changing global climate. Fewer have heard about the other consequence of rising CO2 levels- when the CO2 is absorbed into the oceans, it disassociates into carbonic acid. This alters the pH of our world's oceans, and it's called "Ocean Acidification". This changing ocean chemistry has many important and devastating consequences. [more inside]

By popular demand, your new resident marine biology nerd has compiled some cool information about the Giant Pacific Octopus.The Giant Pacific Octopus (Octopus dofleini) is one of the strangest animals in the sea- and one of the smartest. Though it is commonly believed that vertebrates are always "smarter" than invertebrates, these guys defy that convention. As this video shows, they are able to easily open jars and retrieve food from inside. They are also, as the "Giant" implies, enormous- the biggest one on record was 30 feet across (according to National Geographic) [more inside]

Is salvaging sunken treasure a form of piracy or the preservation of history? Does commercial for-profit exploration of historical shipwrecks taint the historical legacy of these naval graveyards? Who owns the treasures lost for so many centuries? Marine archeology is testing its legal limits with one man's work. [previous]

The Jupiter Foundation and the Whalesong Project are both organizations which record humpback whale songs from floating buoys; some of their archived recordings can be found here, here, and here. (Warning, last two may resize your browser.) DOSITS hosts a more comprehensive collection of oceanic sounds, with seals and fish along with its whales and dolphins. It also has a couple of nice sections on how animals use sounds in the ocean. (Previously.) [more inside]

A Global Map of Human Impacts to Marine Ecosystems "What happens in the vast stretches of the world's oceans - both wondrous and worrisome - has too often been out of sight, out of mind. The goal of the research presented here is to estimate and visualize, for the first time, the global impact humans are having on the ocean's ecosystems."

An "order of magnitude older than the dinosaurs," even older than clams, bugs, vertebrates, are jellyfish. At almost 600 million years old, jellyfish are some of the oldest animals on the earth that have survived the test of time. Dr. Lisa-ann Gershwin, (yes, of that Gershwin family) is a scientist studying jellyfish in Queensland, Australia and was recently interviewed by the ABC. I was particularly disturbed by her gripping description of the tiny Irukandji jellyfish and how the venom affects humans. This summer, swim at your own risk.

Heavy Seas is an all too brief gallery of terrifying photos of huge waves crashing down around large boats & drilling rigs. I wish it were a little longer, but I did think the photos were impressive, as one who has never been at sea in very rough weather.
