Great white sharks are only cool when they are gnawing on someone else’s boat. This week, tourists on a South African shark-diving tour got the shock of their lives when they watched one great white take the bait next to their boat – just as a second great white leapt out of the water behind it! I knew sharks couldn’t take selfies, but apparently photo-bombing isn’t out of the question.

In honor of this weeks gnarly shark footage I’d like to post a few amazing pics from Chris and Monique Fallows – who spend 200 days a year at sea.
Photographing great white sharks for 20 years gives Chris and Monique Fallows front row seats on the amazing behavior and secrets of formidable predators few people see. In this post they share ten of their favorite images of great whites.
This adorable seven-inch, deep sea octopus is a species rarely seen by humans. In fact, very little is known about the life history of these animals. They are small, fragile, and gelatinous, with relatively large eyes. The funny thing is they don’t have a name yet!

Stephanie Bush, a postdoctoral fellow at the Monterey Bay Aquarium Research Institute (MBARI), is researching this cartoony creature and has the difficult task of finding it an appropriate name. Until they know what to formally call it, researchers are simply referring to it as the “flapjack octopus,” which belongs with its cousins in the Opisthoteuthis family.
“I was thinking about what my options are [for naming it], and I wanted it to be something indicative of the characteristic of the species. Since they’re so cute, I thought I could name it the Opistoteuthis adorabilis,” Bush told ABC News.
They have a well defined web just under their tentacles that allows them to parachute around the water. The fins above their eyes helps them steer!
In their exhibit at the Monterey Bay Aquarium, these un-described cephalopods live in a tank specially designed to imitate the cold, low-oxygen environment of their deep-sea habitat.
The image below shows the flapjack octopus (Opisthoteuthis sp.) on exhibit. Researchers use a red light to display this species because the octopus can’t see red light. This makes it think it’s safe in the darkness of the deep sea, just like its natural habitat.

Bush and her MBARI team collected about 15 specimens last year using a remotely-operated vehicle along Monterey Canyon in the eastern Pacific. Those little guys now live at the Monterey Bay Aquarium.

I have to admit, I’m a bit terrified of deep sea creatures. I mean, 95% of the ocean floor remains unexplored. That is A LOT of room for giant squid to roam. Lucky for me, NOAA decided to explore the waters off of Puerto Rico in search of the deep sea life that haunts my dreams.
From April 9 to April 30, 2015, NOAA Ship Okeanos Explorer explored largely uncharted deep-sea ecosystems and seafloor in the vicinity of Puerto Rico and the U.S. Virgin Islands. What they found – using state of the art technology – will amaze you!
Quartz posted this incredible video to their Facebook page, using footage gathered from NOAA. Some of these creatures are so new – they don’t even have names.
Océano Profundo 2015
Legs 1 and 2 of the mission focused on mapping the seafloor where primarily only low-resolution satellite or topographic data existed previously. Leg 3 of the expedition featured some of the deepest remotely operated vehicle (ROV) dives ever conducted in the region and collected critical deep-water environmental data that will improve ecosystem understanding and inform federal and local resource managers.
Why Puerto Rico?
According to NOAA, a diversity of seafloor features lie just offshore Puerto Rico and the U.S. Virgin Islands that include trenches, seamounts, numerous submarine canyons, valleys, and troughs. These features likely contain valuable and vulnerable ocean resources, but very little is known about them, making this an important area to survey.
It is crucial to explore this area for several reasons:
It is tectonically active, with seismic hazards
It includes a large section of U.S. Exclusive Economic Zone
One of the major fisheries in the area is deepwater snapper, but little is known about snapper populations there
It is of potential interest for marine protected area managers, those creating ocean usage planning maps, and sanctuary managers

Communication Technology
NOAA did a fantastic job of documenting their journey, allowing scientists and the public access to mission logs, daily reports, photos, video, and live underwater video feeds.
During the dives, Okeanos Explorer’s two-body ROV system continuously captured high-definition video, which the ship transmitted to the Office of Ocean Exploration and Research’s website, www.oceanexplorer.noaa.gov, where anyone could follow along in near-real time!
NOAA Ship Okeanos Explorer uses telepresence technology to transmit data in real-time to a shore-based hub where the video is then transmitted to a number of Exploration Command Centers located around the country as well as to any internet enabled device. Access to the video and a suite of Internet-based collaboration tools allow scientists on shore to join the operation in real-time and allows the general public to follow along with the expedition.

Okeanos Explorer
NOAA Ship Okeanos Explorer, “America’s Ship for Ocean Exploration,” is the only federally funded U.S. ship assigned to systematically explore our largely unknown ocean for the purpose of discovery and the advancement of knowledge. Telepresence, using real-time broadband satellite communications, connects the ship and its discoveries live with audiences ashore.

Her name is Rambo, she lives in New Zealand, she takes pictures, and, oh yeah… she is an octopus! In a new viral video released by Sony, you can see Rambo in action, snapping pics of excited guests in exchange for treats – using Sony’s underwater Cyber Shot TX30 camera.
Rambo, who was given the name based on the amount of destruction she caused the first few camera set-ups, lives at the Kelly Tarlton’s Sea Life Aquarium in Auckland. Rambo may be the world’s first professional ‘octographer,’ given the fact each photo costs $1.50 a pop!
The truth is, octopuses are highly intelligent. They open jars, make daring escapes from their tanks, and even dismantle high tech equipment! Click here to watch an octopus break apart a camera.
Mark Vette, Rambo’s trainer, told Cult of Mac, “When we first tried to get her to take a photo, it only took three attempts for her to understand the process. That’s faster than a dog… Actually, it’s faster than a human in some instances.”
Octopuses learn quickly and are highly motivated by food. Rambo was first taught to respond to a buzzer – which meant snack time. Then Vette had to teach her the buzzer meant to take a picture, which resulted in food.
Vette told NPR the hard part wasn’t training Rambo to shoot pictures; the hard part was creating an underwater set-up for the tank that the curious cephalopod wouldn’t destroy.
He told NPR, “She took the camera, ripped it off its hinges, ripped it off everything, smashed it to bits and spat it out.” Hence the name Rambo 🙂

How Does the Octopus Seamlessly Co-ordinate Its Eight Arms?
Good thing octopuses don’t dance, because according to a new study, they have no rhythm.
Scientists found that the octopus moves by shortening and elongating its arms, which creates a pushing thrust. The animal does not move by bending or pulling its arms, as previously thought.
Octopuses have bilateral body symmetry, which means their left side is a mirror image of their right. Most bilateral-symmetric animals face forward when they are moving (except the crab, which walks sideways.) But, octopuses can move in ANY direction without needing to turn their bodies. They just push off a surface and propel themselves wherever they’d like.
“So the octopus only has to decide which arm to use for the pushing – it doesn’t need to decide which direction this arm will push,” explained Dr Levy. “[It has] found a very simple solution to a potentially complicated problem – it just has to pick which arm to recruit.”
While, the octopus clearly has some rad moves, researchers have not been able to spot a pattern, or rhythm to their movement. Levy believes there either is no pattern to discover, or their movement is too complicated for the studies they conducted.
The findings are published in the journal Current Biology.
