Australian scientists are seeking a "mystery sea monster" that likely swallowed a 9-foot great white shark. Most likely, it was an even bigger great white shark, specifically a 2-ton "colossal cannibal great white shark."

Scuba diver Jason Dmitri's encounter with a shark was caught on film, but he bears no grudge for the beast that tried to get a piece of him.
"The shark was acting in his natural environment," Dmitri wrote on his YouTube page. "I have no ill will toward him and will get back in the water and continue to protect the reef for future generations."

Marine Biologist, blogger, and science-tweeter
David Shiffman sends word to Boing Boing readers of a wonderful opportunity to support shark research, and have a close encounter of your own with these beautiful creatures:
Have you always wanted to be a marine biologist? Have you been fascinated by sharks since you were young? For me, the answer to both questions is yes...and I'm currently living my childhood dream! I'd like to invite you to join me for a day of shark research with my lab, the University of Miami's RJ Dunlap Marine Conservation Program (SharkTagging.com and Facebook.com/SharkTagging). I'm participating in the 4th SciFund Challenge (SciFundChallenge.org), a crowd-funding event for scientific research.
The reward for a $400 donation to my project is a day on our lab's shark research boat!

Last week, scientists described a new species of hammerhead shark, the Carolina hammerhead. Though slightly smaller than the scalloped hammerhead species it was previously thought to be a part of, the Carolina hammerhead was ID'd as something different with the help of DNA samples, not visual descriptions. This, courtesy shark blogger David Shiffman, is the Carolina hammerhead's head, in beautiful x-ray vision.

At Slate, shark scientist and blogger David Shiffman breaks down the risks that swimmer Diana Nyad was really taking this week when she swam from Cuba to Florida
without a shark cage. The mere phrase "without a shark cage" makes this sound like a huge risk
, Shiffman writes. But the historic swim, itself, is the real achievement. The sharks weren't actually that big of a danger. (BONUS: An explanation of how, exactly, one is supposed to swim long distances inside a shark cage, to begin with.)
Researchers from the University of Delaware snapped this fantastic photo of a dogfish swallowed by a sand tiger shark. The scientists were in the Delaware Bay seeking tagged sharks to better understand their behavior.
"This unlucky smooth dogfish couldn't resist the menhaden used as bait and, unfortunately, fell victim to one of the top predators in the bay," according to a posting by the University's Ocean Exploration, Remote Sensing, Biogeography (ORB) Lab. "The dogfish was about 3 feet (1 meter) long and completely swallowed by the sand tiger shark."
David Shiffman, a fantastic scientist and ocean blogger, has spent the past week correcting the errors of Discovery's increasingly misleading Shark Week
programming. Tomorrow, at noon eastern, he'll be on Reddit for a shark-centric round of "Ask Me Anything"
. Got shark questions? David Shiffman will have sharp answers.
Psst, hey kid. You wanna see some clips from the dissection of one of the largest mako sharks ever caught? Sure you do.
This NOAA video has amazing footage of the shark's stomach — so big it fills a tall Rubbermaid tub — and the even more amazing footage of scientists lifting an almost completely intact sea lion head out said shark's stomach.
What's the benefit? Studying the stuff in a shark's stomach helps us understand how different species are interrelated — which helps scientists figure out how to better manage the conservation of whole ecosystems. Essentially, write the good folks at Smithsonian.com, this is an example of scientists making valuable use out of a not-exactly-ideal situation. The shark was legally caught and killed by fishermen filming a scene for a reality TV show.
Shark attack stats

: "The real threat is humans. For every one human killed by a shark, there are approximately 25 million sharks killed by humans."
About 200 million people go to U.S. beaches each year. About 36 of those hundreds of millions are attacked by sharks. Most of them survive. In contrast, more than 30,000 of those millions of beach-goers are to be rescued from surfing accidents. And many of those humans each year die, or must be rescued, from drowning incidents in which no other creature is to blame.
So, will we see Human Week, or Human-nado mockumentaries any time soon?
Your chances of being killed by a shark are 1 in 3.8 million. But, you know, just in case
, here's what you do to survive a shark attack
Megalodon is dead, to begin with. (Not that you'd know that from watching the Discovery Channel's recent intentionally fake, but presented as factual, documentary on the subject.) But the extinct giant shark — 3x the length of a Great White and 10x the mass — is still pretty damn fascinating. Check out this actually factual treatment of the biggest shark that ever lived
at The Contemplative Mammoth blog.
This Shark Week, the seals of the world would like to take a moment to remind you that appearance isn't everything. Scary-looking creatures might not actually be that much of a threat to you. Adorable ones are not necessarily as cuddly as they let on.

A fisherman from Victoria, Australia, climbed inside the shark he had captured, poked an arm through its lifeless gills, and staged this incredible shot for posterity. From Perth Now:
First reported by 3AW, a radio station in Australia
"An American couple have turned up at the Metung Hotel to see this photo and their immediate response from the wife was 'Did he survive!?'." The fisherman was standing right behind her at the time. Presumably, his answer was "yes".
, the fisherman isn't named. But show host Ross Stevenson declared it their "photo of the year" on the spot. [via Gawker
This is an older piece, but given that we're into hurricane season, I expect it will come up again. How do you tell if the photo you've been forwarded, showing sharks swimming through flooded urban landscapes, is real or fake? Marine biologist (and shark expert) David Shiffman has a simple 5-step process. In fact, it's so simple that I'm sure many of you will already be familiar with these tricks. But, here's the thing, it's helpful to be reminded that the tricks are necessary. They're very easy to forget when a hurricane is crashing into shore and social media is blowing up. Besides which, this will make a handy link to forward to friends and family passing questionable photos of all sorts.
