Dear Shark Week, Your official motto is “Be careful what you fish for.” That is some witty wordplay! Were you aware that over 30 percent of shark species are endangered due to overfishing? Not as c…

UK’s Deep Sea Mountain Life Filmed
by Victoria Gill, BBC
Scientists have sent a remotely operated vehicle to film one of the UK’s three undersea mountains, known as seamounts.
The Hebrides Terrace Seamount, off the west coast of Scotland, is higher than Ben Nevis, but its peak is 1,000m beneath the surface.
Prof J Murray Roberts, from Heriot-Watt University, and his colleagues filmed more than 100 species on its slopes.
They published their findings in the open access journal Scientific Reports.
Prof Roberts has now shared the footage from the dive exclusively with the BBC.
He and his team used a remotely operated submersible vehicle to explore and film the aquatic mountain slopes.
"These are vast structures in the ocean," Prof Roberts explained to the BBC.
"They’re exciting because they grow up through the ocean and have steep sloping sides. [When] the currents hit the sides of the seamount and they stir up nutrients, they become really productive areas."
Prof Roberts and his colleagues watched from a ship-based laboratory while their rover explored the depths.

The tiny plastic particles polluting our seas are not only orally ingested by marine creatures, but also enter their systems through their gills, according to a new study. When microplastics are drawn in through this method they take over six times longer to leave the body compared with standard digestion.
Our poor friends with gills…
It’s a normal part of every summer vacation: Head to the beach, pick up a few seashells, and take them home as keepsakes.
S/he should’t sell (or collect) seashells from the seashore.

Me and Photoshop/ Illustrator have been best friends lately. What do you guys think? Do they show how awesome our volunteer programme is? Because it is. Or I wouldn’t be here.
Slow Life of Corals and Sponges by Daniel Stoupin
”To make this little clip I took 150000 shots. Why so many? Because macro photography involves shallow depth of field. To extend it, I used focus stacking. Each frame of the video is actually a stack that consists of 3-12 shots where in-focus areas are merged. Just the intro and last scene are regular real-time footage. One frame required about 10 minutes of processing time (raw conversion + stacking).”
Where Sea Turtles Spend Their ‘Lost Years’
ERIK STOKSTAD | Science NOW
Now, researchers have published the first satellite tracking data from young sea turtles, charting a leisurely voyage under the sun. The youngsters idly float north along the Gulf Stream, then head toward the Azores. Along the way, they spend most of their time riding the waves, and the sun helps raise their body temperature. “The data from this handful of turtles could lead to some really important developments” in understanding turtle populations, says Nathan Putman, a turtle biologist at Oregon State University, Corvallis.
The early life of loggerheads and other sea turtles used to be called “the lost years,” because no one knew exactly where they went. But over decades, researchers pieced together the animals’ natural history from ship observations, the pattern of ocean currents, and other data. More recently, other scientists have studied isotopes from turtle tissue to analyze their diet and past locations and created computer simulations of their journey. The basic picture is this: Hatchlings head out to sea to avoid fish, sharks, and other predators. Once off the continental shelf, they eventually end up in a current, called the North Atlantic subtropical g. A few years later, they come back to their birthplaces on the East Coast of the United States.
The transmitters survived between 27 and 220 days, during which some turtles roamed as far as 4300 kilometers, the team reports today in the Proceedings of the Royal Society B. As expected, the turtles all headed north with the Gulf Stream, then most turned eastward around Cape Hatteras in North Carolina. The paths were consistent with what Putman’s computer models had predicted. The turtles weren’t single-mindedly heading toward the Azores, but looping around in small eddies and trying to avoid the coldest water. They also spent almost all of their time on the surface, and Mansfield suspects that this is to help stay warm. “It’s kind of a common sense thing,” Mansfield says. (They may also be waiting to develop the lung capacity for diving.)
Baby Black Ribbon Moray Eel
There are over 200 species of Moray eels. Worldwide, not one of them had been successfully bred until recently. At Zoo Vienna Schönbrunn in Austria, a Black Ribbon Moray laid a clutch of fertilized eggs. This fact alone is quite a sensation. But it gets better: some larvae even hatched!
"It is the first time that the hatching of Morays could be observed. Up to now, nobody knew what the larvae look like, what they eat and how they behave“, explains the zoo’s director Dagmar Schratter.
The breeding of Morays is completely new territory. The successful event in Schönbrunn Zoo supplies the first information - completely unknown up to now - about the development of their eggs and larvae.
Crowd-funding is the coolest new way to fund science research. I even got an email through coral-list about it this morning.
JR here is looking into the sex of (critically endangered) sea bass. The funds will pay for a data-logging hydrophone (underwater camera) that costs $6000 + and is crucial for the research.
Put good out in the world, you never know when you’ll need it in return. And who doesn’t want to know more about Giant Fish Sex?
