On Saturday, Danny McDaniel was kayaking near Santa Catalina island off the southern California coast when he felt something big strike the side of his boat. It was a great white shark that Ben Frable, Marine Vertebrates Collection Manager at the Scripps Institution of Oceanography later estimated to be 17-20 feet long. How did they know how big it was? They measured the teeth left lodged in the kayak. From CNN:

"I felt like I was being pushed like a toy in the water," said McDaniel, who lives in San Diego.
The shark had sunk its teeth into the back end of the boat and pushed McDaniel around till he was face-to-face with (his kayaking partner in another boat).
"The whole upper body of the shark was out of water," he said. "It was humongous."
The shark soon let go and went deep into the water, according to McDaniel, who said the whole ordeal lasted about five seconds...
"It is pretty amazing and encouraging that such large animals are still able to exist out there with fishing activities and human encroachment and environmental change," Frable said.
"Big individuals like these, especially if they are female, are very important for species' health and survival as they can produce and have produced more offspring than others."
Jeff Crilly and his friends were participating in a mako shark fishing tournament off the Jersey Coast when a different kind of shark came by for a snack of chum. Yes, they're gonna need a bigger boat. John Chisholm, a shark expert at the Massachusetts Division of Fish and Wildlife, estimates the 16- to 18-foot Great White weighs as much as 3,500 pounds.
From the Asbury Park Press:
Chisholm keeps a running database of great white sharks he's identified by certain features, such as markings. Crilly's shark had white markings on its gills, which Chisholm found no matches for in the hundreds of sharks logged in the database.
"She wasn't in there. I was able to determine it was a new shark and if we ever see it again, we'll be able to identify her," Chisholm said.
Chisholm invited Crilly to name the animal and he dubbed her Sherri. After his mom. Read the rest
Yesterday, a guest on the 28th floor at the Tidewater Resort on Panama City Beach caught this video of a big shark circling a lone woman who had no idea the animal was nearby. Eventually people on the beach noticed the shark and yelled to the woman to return to shore. I don't know what kind of shark it was, or whether it was hungry, but I am certain that this video would be more interesting with the soundtrack below. (News Herald)

An astonishing school of hammerhead sharks surprises divers at Darwin's Arch in the Galápagos Islands in this majestic video from the BBC's Mission Galápagos series. In an article at Wanderlust, Mission Galápagos host and animal biologist Liz Bonnin lists this adventure as one of her "most amazing wildlife experiences":
The hammerheads come from all different directions and gather, swim around each other in big circles in a wonderful sort of balletic association. At the very centre of this big mass of hammerheads are the oldest, most mature females. The younger sharks swim around them. When the males come in to mate, they’ve got to weave and wind their way through this mass of hammerheads, so only the strongest, fittest males will get to mate with the females in the centre.
We are only just beginning to understand the purpose of this mass congregation, so the more scientists dive down there, the more they’re understanding its importance. It’s a very special place, and a very important behaviour, that needs to be protected. The Galapagos is one of the last jewels of this blue planet of ours. It really needs extra protection of ours oceans to make sure that that doesn’t disappear for ever. It was extraordinary.

TIL: Sharks are attracted to the sound of death metal. Apparently, the "dense tones" of it mimics the "low frequencies of struggling fish." (Damn.)
In 2015, a Discovery Channel crew -- hoping to attract a large great white named "Joan of Shark" -- dropped a speaker underwater and played some.
Desperate to feature the 16-foot, 1.6 tonne shark in their documentary, they submerged a speaker to see if the shark would react. Unfortunately they didn't manage to attract Joan, but did catch the attention of two others, one of which was 12 feet long.
Sharks 'hear' by picking up vibrations from receptors on their bodies, meaning they can be attracted to the low-frequency vibrations of heavy music, which apparently sounds like struggling fish.

Watch marine biologist Ocean Ramsey (yes, Ocean is her first name!) swim with a 20-foot great white shark off the coast of Oahu, Hawaii. First spotted off Guadalupe in 2014, this animal, nicknamed "Deep Blue," is thought to be the largest great white in the world. They're definitely going to need a bigger boat.
“We never would have imagined we would be fortunate enough to be graced with the presence of this massive, big, beautiful, female white shark," says Ramsey, who at the time was observing tiger sharks with her One Ocean Research team. “It fills my heart with joy and takes my breath away.”

A fantastic behind-the-scenes clip from Blue Planet II:
The Blue Planet II team dive to over 700 meters to see what happens to a whale carcass on the seabed. Whilst filming sharks as they feast, the sharks start to take a worrying interest in the submarine!

A great white shark washed up today on a popular Sydney, Australia beach. Manly Sea Life Sanctuary transferred the juvenile shark to a nearby swimming pool to recover before they release it into the ocean in the next couple days. According to The Independent, "The pool will remain closed until the shark is released."

Lagrangeville, New York police found seven live sharks and three dead ones in a basement pool inside a home. The sandbar, leopard, and hammerhead sharks were between two and four feet long.
According to the Associated Press, "marine wildlife experts took blood samples and measured and tagged the sharks before transferring them to the Long Island Aquarium in a truck equipped with water tanks, oxygen and climate control."
An investigation is underway. Sounds to me like a low-budget supervillain's lair. Read the rest

Terry Selwood, 73, was fishing near Evans Head, New South Wales, Australia when a nine-foot great white shark jumped onto the deck of his boat.
"I caught a blur of something coming over the boat … and the pectoral fin of the shark hit me on the forearm and knocked me down on the ground to my hands and knees," Selwood told ABC. "He came right over the top of the motor and then dropped onto the floor... There I was on all fours and he's looking at me and I'm looking at him and then he started to do the dance around and shake and I couldn't get out quick enough onto the gunnel."
According to the Evans Head Marine Rescue Unit, they arrived to find the shark on the on the boat and Selwood "covered in blood with numerous lacerations on his right forearm."
Selwood received stitches and is now fine. The dead shark was delivered to the Department of Primary Industries for study.

Never be caught unawares by a shark again with the Global Shark Tracker. There are apps for mobile platforms, but it doesn't work very well on a small display. Always go with a bigger boat.
In a collaborative environment established by Founding Chairman and Expedition Leader Chris Fischer, OCEARCH shares real-time data through OCEARCH’s Global Shark Tracker, inspires current and future generations of explorers, scientists, and stewards of the ocean, and enables leading researchers and institutions to generate previously unattainable data. OCEARCH has completed 26 worldwide expeditions.
In 2015, OCEARCH open sourced the data on the Global Shark Tracker to 2.3 million users, achieved an annual global reach of more than 12.2 billion media impressions, a Facebook reach of 150 million impressions, and a Twitter reach of 36 million impressions.
OCEARCH expeditions and digital outreach platforms are enabled through the support of Costa Sunglasses, YETI, Yamaha, Contender, SAFE Boats, and oneQube.
You can follow the OCEARCH tagged sharks by accessing the near-real time, free online Global Shark Tracker, by downloading the Global Shark Tracker App available for Apple and Android platforms, or by following OCEARCH on all social media platforms: Facebook, Twitter, Instagram, and YouTube.
As fascinating as the map is, its creators are described as unscientific Jacques Cousteau wannabes whose methods of tagging sharks are held in some disrepute.

“Shark Wranglers” is the same crew (minus Dr. Michael Domeier) formerly featured on the show “Shark Men” on the National Geographic Channel, which itself used to be called “Expedition: Great White.” These guys specialize in a unique, possibly unnecessarily-invasive procedure to catch and tag large sharks.
