Hooked white shark bites swimmer off Manhattan Beach

The AP reports, that a long distance swimmer suffered injuries as the result of a bite from a sub-adult white shark (Carcharodon carcharias) of off Los Angeles County’s Manhattan Beach yesterday morning. According to an NBCLA report, the shark had been hooked by a fisherman on Manhattan Beach Pier and had been on the line for about a half-hour when a group of swimmers intersected the hooked shark’s path.

Steve Robles of Lomita, CA was bitten in the chest area and also suffered injuries to his right hand. A paddle-boarder helped Robles to the shore where he was treated by paramedics and transported to a nearby hospital. Thankfully, Robles injuries were not life-threatening, and he is currently recovering at home.

The fisherman told NBCLA that he was fishing for bat rays when he hooked the shark. He said he didn’t realize it was a white shark until after it had been on the line for 15 minutes. California law dictates that the line must be cut if a white shark is hooked, but he said the shark was close to a surfer when he recognized the species, and he didn’t want it to attack the surfer.

It should be noted that a white shark of this size, which was estimated at 7′ (about 2m) in length, does not typically feed on marine mammals or large prey items.

NSU Shark-tracking Website Helps Viewers “Dive Into Shark Week”

HOLLYWOOD, Fla. – Nova Southeastern University’s (NSU) Guy Harvey Research Institute (GHRI) will help shark enthusiasts take their Shark Week 2013 to the next level with an interactive website that tracks four shark species (mako, tiger, oceanic white tip and sand tiger) around the world. Users can interface with the technology to see where and how far the sharks travel over time.

The NSU Guy Harvey Research Institute shark-tracking website can be accessed at:
www.nova.edu/ocean/ghri/tracking/.

“This multi-species shark tracking site provides an eye-opening perspective on the secret pathways and enormous distances that some sharks can cover during their seasonal migrations,” said Mahmood Shivji, Ph.D., director of NSU’s Guy Harvey Research Institute and the Save Our Seas Shark Research Center.

Eighteen sharks (makos and oceanic white tips – see names below) are currently reporting their whereabouts in the open ocean almost daily, and their wanderings can be followed in near real time on the web site, revealing novel information about their movements.

“Understanding where these animals migrate to and when they do it is crucial to their conservation,” says Guy Harvey, Ph.D. “The Guy Harvey Research Institute is a worldwide leader in shark tagging and research. Dr.
Shivji and his GHRI team have been able to record some of the longest tracks in the modern history of shark research.”

The longest recorded track is a Tiger Shark affectionately referred to as Harry Lindo. Harry was tagged in Bermuda in 2009 and tracked for more than 3 years, providing an unprecedented long-term and detailed view of its migrations. During that time, Harry covered a remarkable distance of over 27,000 miles.

The NSU/GHRI shark tagging program, which began in 2009, has now gone worldwide, and includes New Zealand and West Atlantic mako sharks; tiger sharks in Western Australia, Bermuda, Grand Bahama, Bimini Chub Cay, and Grand Cayman; oceanic white tip sharks in the Bahamas and Caribbean; and sand tiger sharks in the Atlantic. Shark researchers at NSU have discovered interesting patterns while tracking the various species, including:

Seasonal Patterns:

Tiger sharks tagged in Bermuda that were tracked for 2-3 years show a seasonal pattern that they repeat year to year. They move to Bahamian and Caribbean waters during the winter, and then move to open ocean in very deep waters northeast of Bermuda where they spend a couple of months each summer before returning to warmer locales for the following winter.

Deepest Dives:

Pop-up tags allow researchers to look at swimming depth as well as location data. At least one tiger shark and a shortfin mako shark were recorded swimming at depths of nearly 900 meters (nearly 3,000 feet).

Fastest Shark Species:

Shortfin mako sharks can reach speeds of approximately 60 miles per hour for short bursts. Long-term movements for this species are not well known, but current tracks on animals tagged by the GHRI team off Ocean City, Maryland, monitored one animal as it traveled nearly 2,000 miles in the first 42 days after it was tagged. A mako named JoAnn (tagged off Isla Mujeres, Mexico) traveled approximately 3,200 miles in 91 days since she was tagged. And yet another mako named Carol (tagged off New Zealand) travelled to Fiji and back, covering at least 10,000 miles over the course of just over 11 months.

The equipment – Two types of transmitters

SPOT Tags

SPOT Tags are mounted to the fin of the shark and have an antenna that extends upward. These tags have a saltwater switch/sensor that tells the tag when it is out of the water. When the tag breaks the surface of the water, it transmits its location to a satellite, allowing researchers to track the animal over the life of the tag’s battery (typically 10 to 30 months).

Pop-up Tags:

Pop-up tags are archival satellite tags that are typically inserted into the shark’s top surface by its dorsal fin and collect and store data within the tag. After a pre-determined amount of time, the tag releases from the shark, floats to the surface and transmits the stored data to a satellite from which scientists can determine the position of the shark, its depth and the temperature of water in prefers to spend its time in.

Newport Aquariums newest shark ray dies of mating injury

The Newport Aquarium boasts having the “largest collection of shark rays on display in the world.” However, the aquarium is down one shark ray after their latest addition, a 6-year-old female, died on Monday, according to a USA Today report.

Shark rays (Rhina ancylostoma), also known as bowmouth guitarfish, have a distinctive appearance with broad rounded head like a “traditional” ray with dorsal and caudal fins similar in appearance to sharks. The species is typically found in Indo-Pacific waters and spends most of its time on the ocean floor. The shark ray is listed as “vulnerable” on the IUCN red list.

The Newport Aquairum’s newest shark ray was recently added to the “Shark Ray Bay” last week. The mating process for the species typically involves the biting down on the female’s pectoral fin to hold her. The aquarium’s curator said the in this instance the male bit the recently added female in the abdomen. She was removed from the exhibit when aquarium staff noticed she was in distress. An ultrasound revealed internal bleeding which resulted in the shark ray’s death.

Sharknado premieres July 11 at 9/8c on SyFy.

Discovery’s “Snuffy the seal” Shark Week promo

DiscoveryNetworks YouTube channel recently added the first promo for its 2013 Shark Week. The over-the-top style ad features the fictitious “Snuffy the seal” as his return to the wild is being celebrated following his rescue and rehabilitation. Poor Snuffy doesn’t make it very far, though, as a breaching white shark snaps him out of the air before he ever makes it back to the sea.

It looks like Discovery is going with the tagline of “it’s a bad week to be a seal” for this year’s edition of the much celebrated week of shark-themed programming, but they go on to say that “it’s pretty awesome” for the rest of us. I guess the rest of us will just have to wait until August 4 to see for ourselves.

What do you think of Discovery’s latest promo for Shark Week 2013? Sound off in the comments below!

Video: great white shark filmed off New Jersey coast

WARNING: Video features language that some may find offensive.

YouTube user Rob Pompilio recently posted a video featuring a white shark (Carcharodon carcharias) off of the coast of New Jersey. According to the video description, the footage was shot on January 9, 2013 about 30 miles from shore. Atlantic white sharks are known to travel north along the east coast of the U.S. during the summer months seeking cooler waters, as temperatures rise during the summer months.

“Great White Shark” opens in IMAX 3D

A new IMAX 3D film titled “Great White Shark” premiered over the weekend in select cities. The film aims to “unravel the mystery” of the great white shark (Carcharodon carcharias) and tell the true story of its role as an apex predator in the ocean environment. The mission of the film is to change the public’s perspective and attitude toward the great white shark.

You can visit the film’s official website for a list of upcoming locations and release dates of “Great White Shark.”

Researchers test new “eco-friendly” shark barriers

eNCA reports that researchers from Stellenbosch University are performing a test trial of a new “eco-friendly” shark barrier near Dyer Island off the coast of Gansbaai, SA.

The Sharksafe Barrier System consists of connected rigid pipes that span from the ocean floor to the surface. The system is designed to resemble kelp and emits a “magnetic barrier,” which will deter sharks from attempting to swim through the artificial barrier, according to the team who developed the system.

Unlike “traditional” shark nets that indiscriminately kill various forms of marine life, the Sharksafe Barrier System is designed to serve as a physical barrier to merely deter sharks from passing through. The system will span from shoreline to shoreline, as well as from the sea floor to the surface, to create an all-encompassing barrier, unlike traditional nets.

In addition to researchers from Stellenbosch University, PhD candidate Craig O’Connell (University of Massachusetts Dartmouth) and renown diver and white shark conservationist Mike Rutzen have collaborated on the project, which has been under development since 2011. The team plans to finish testing the barrier within the next month before submitting requests for permission to use the barriers at Cape Town’s Muizenberg and Fish Hoek beaches.

MA great white shark license plate campaign nears halfway mark

The Atlantic White Shark Conservancy’s 60-day campaign for Massachusetts great white shark license plate pre-orders is about at the half-way mark. The minimum number of pre-orders required to make the license plate a reality is 1,500. Unfortunately, the current number of pre-orders sits at 245, according to the white shark license plate campaign site.

If you’re a Massachusetts resident who would be interested in adorning your vehicle with a snazzy-looking great white shark license plate, head on over to the campaign site and reserve your plate for $40 before time runs out. If you know a Massachusetts resident who might be interested in the plates, please spread the word.

For non-Massachusetts residents, would you be interested in a similar shark-themed license plate if your state/province offered it? Sound off in the comments below.

Kayaker has close encounter with mako shark off Perth, WA

Grant Bond got a little more than he bargained for off of Perth, Western Australia earlier this year. Bond was fishing from his kayak when a shark decided to get up close and personal with him. He thought at the time of the encounter that it was a white shark (Carcharodon carcharias) giving his kayak a workout, but after reviewing the footage he was able to identify the species as a shortfin mako (Isurus oxyrinchus).

When Bond first encountered the mako, it was circling his kayak, and after about five minutes he thought the shark had left the area. It was at this point that the shark, estimated at 3m in length, starting bumping the kayak. Rather than playing a game of bumper-boats with the shark, Bond decided to call it a day and head back to shore. Bond believes that the shark was attracted to his kayak by some herring in the foot well. He threw the herring as far from the kayak as he could, cut his anchor line, and headed in under sail.

Bond went on to point out that even though the mako nudged and rubbed up against his kayak multiple times, it never bit the vessel. He said the old adage about the worst day of fishing being better than the best day of work turned out not to be true, after all. Thanks to Grant for sharing this video!

Note: There was a typo in the date on the video, which was shot on March 10.
