A research crew from Japan’s National Science Museum have managed to capture on film for the first time a giant squid (Architeuthis) in its deep sea natural habitat. Working with Japanese public broadcaster NHK and the US Discovery Channel, the researchers found the massive invertebrate at a depth of a depth of 630 metres as the animal was holding on to bait swimming against the current in the depths. The footage was filmed in the Pacific Ocean near the Ogasawara Islands, 1000 km south of Japan, an area where two previous sightings in 2006 and 2012, have been reported. Continue reading
The appearance of the world’s rarest whales has been recorded for the first time after a mother and her calf washed up on beach in New Zealand in 2010. Spade-toothed beaked whales (Mesoplodon traversii [IUCN]), aka Bahamondi’s or Traver’s beaked whales, are so rare that they have yet to be seen alive and only recently have scientists confirmed that a five-meter specimen found alongside its male offspring two years ago belonged to the rarest species of whales.

The following outstanding 2 hour video shows the amazing biodiversity of the marine life in the Andaman Sea (in the northeast Indian Ocean). Produced by Nick Hope at Bubble Vision, he again amazes us while introducing us to many rarely seen marine species the way they should be met, in their home under the sea.
“The BP oil spill, the largest ever oil spill on open water to date, contributed significantly to the historically high number of dolphin deaths in the Gulf of Mexico, says a two-year scientific study released July 19. A variety of other environmental factors contributed.
A research team of biologists from several Gulf of Mexico institutions and the University of Central Florida in Orlando published their findings in the journal PLoS ONE.”

If the pictures of those towering wildfires in Colorado haven’t convinced you, or the size of your AC bill this summer, here are some hard numbers about climate change: June broke or tied 3,215 high-temperature records across the United States. That followed the warmest May on record for the Northern Hemisphere – the 327th consecutive month in which the temperature of the entire globe exceeded the 20th-century average, the odds of which occurring by simple chance were 3.7 x 10-99, a number considerably larger than the number of stars in the universe.
Meteorologists reported that this spring was the warmest ever recorded for our nation – in fact, it crushed the old record by so much that it represented the “largest temperature departure from average of any season on record.” The same week, Saudi authorities reported that it had rained in Mecca despite a temperature of 109 degrees, the hottest downpour in the planet’s history.

This March, a Seattle-based federal judge issued a decision dealing with the continued practice of whaling in Antarctic waters. The court’s ruling, arising from a dispute between whalers and the activists depicted on the TV show, “Whale Wars,” stopped short of declaring whaling to be a violation of international law, but nevertheless declared it to be against the public interest of the United States as reflected in U.S. marine environmental legislation. The court also highlighted the potential importance of a dispute concerning this issue between Australia and Japan, currently pending before the International Court of Justice (“ICJ”).
The International Ban on Commercial Whaling
The hunting of whales, once a major industry in several maritime states, became subject to international regulation in 1946, through the International Convention for the Regulation of Whaling (“ICRW”). By that treaty, which gained widespread adherence, an International Whaling Commission (“IWC”) was established, with power to set annual catch quotas for each member state. Continue reading
Paul Gilding: The Earth is full
“Let me begin with four words that will provide the context for this week, four words that will come to define this century. Here they are: The Earth is full. It’s full of us, it’s full of our stuff, full of our waste, full of our demands. Yes, we are a brilliant and creative species, but we’ve created a little too much stuff — so much that our economy is now bigger than its host, our planet. Continue reading
“In the deepest, darkest parts of the oceans are ecosystems with more diversity than a tropical rainforest. Taking us on a voyage into the ocean — from the deepest trenches to the remains of Titanic — marine biologist David Gallo explores the wonder and beauty of marine life.

More about David Gallo:
The video above is of a sea cucumber feeding. Within the ocean, organisms have adapted many different methods of gathering food. It’s not as easy to find food in water as on land, even within the same species there can be many different methods, just look at fish! You have gigantic whale sharks that filter feed on tiny planktonic creatures, to deep sea angler fish that use a flashing lure that brings food close enough to grab or even the awesome gulper eel that’s stomach is bigger than the body so it can eat a meal of any size.

Sea turtles have been making it to the top of the headlines recently, all positive for a change and I thought I would use this blog to draw attention to this. Additionally, I feel it’s always nice to give some attention to the turtles.
So the first piece of news, the secrets of the sea turtle migration have been uncovered. It turns out that the reproduction migration (females returning to their nesting beaches) is not the longest migration that sea turtles carry out. It has been found from the compilation of long term capture programs that the migration of immature turtles, termed “developmental migration”, is longer than the reproductive migration. Also this migration is only carried out once in their life time rather than every few years. On the migration topic as well, a study was carried out to determine the migration of juvenile leatherback sea turtles. However, due to the size and the weight of the juveniles it is impossible to attach a satellite tag to their shells without them sinking. So instead of following the hatchlings the scientists followed the currents. The “lost years” of a turtle’s life, the age between hatching and returning to foraging grounds can be anywhere between 3 to 5 years after they hatch. These years are the least understood part of a turtle’s life. Knowing more about where the turtles swim before they reach adulthood could be critical in protecting the species. Continue reading
So I should probably begin with part 1…. Back in 1960, January 23rd to be precise, the first ever deep submersible dive occurred by two oceanographers, Don Walsh and Jacques Picard. Using the Bathyscaphe Trieste (above) they reached a depth of 10,911 m (35,797 ft) at the Challenger Deep section of the Mariana Trench, the deepest part of the ocean (11 km or about 7 miles deep). This so far, is still the only time this depth has ever been reached in the ocean by humans with it taking the Trieste five hours to reach the bottom and only being allowed 20 minutes at this depth due to the constraints of technology at the time.

The Smithsonian Tropical Research Institute has released a free iPhone app, for the identification of Pacific fish species. The species covered spans from Baja California to Ecuador, including the Galapagos.
The app evolved from the book, “Fishes of the Tropical Eastern Pacific” published in 1994. However, the app covers over 1,300 species allowing the identification of 10% of the world’s tropical fish species whereas the book only has 700. The app is free on iTunes: here and is potentially one of three apps according to iTunes descriptions.
Having downloaded and played around with this app it is very easy to use. It has a clear lay out containing a notebook section where you can compile your own lists and each page comes with a glossary section for any words used that aren’t understood. When you click on one fish you will also see other members of the family before it goes directly to the profile page, allowing for a perfect match. I like the feature of being able to find out the IUCN red list status which is available on each profile page. A useful little app that I would recommend to anyone needing to identify any pacific fish species!
This remarkable behavior was discovered just a few months ago; a black-marble jawfish (Stalix cf. histrio) following and mimicking a mimic octopus in one of my all-time favorite places at the center of marine biodiversity: the Lembeh Strait, Indonesia.
An outstanding find which shows just how much marine life has yet to teach us….
