The Dorsal Fin

MyFoxNY.com has reported that conflicting accounts of “small” or “baby” sharks seen around Rockaway Beach resulted in lifeguards clearing the water for about an hour on Saturday. Accounts of the shark sightings ranged from one to three sharks being spotted. One witness told NY1 that a shark was tugging on the leg strap of a female surfer and that two more sharks were “circling her.” The scare resulted in swimmers and surfers evacuating the water, but they were allowed to return after an hour. No other subsequent incidents were reported after beach goers were allowed to return to the water.

New York Aquarium‘s Jon Dohlin was quick to point out to the news anchor in the clip above that the sharks are always out there, and the ones that are being reportedly sighted do not pose a real threat to swimmers and surfers. Despite the fact that the sharks being reported are considered to be generally harmless, it hasn’t slowed other media outlets from over-hyping the animals. The New York Post referred to the sharks as “finned fiends” and “toothy terrors,” while the New York Daily News ran with a headline referring to the sharks as “deadly fish.”

Update:Patti Banner, the radio personality seen reluctantly eating the shark meat in the video, has posted a response in the comments section of this post. Please, visit the comments for her take on the event.

Apparently, Discovery Networks’ attempted shark conservation message was lost on KOLA 99.9′s Wake Up Bunch, as radio personality Patti Banner ate shark meat on the air “in honor of Shark Week,” according to the YouTube video information posted by the radio station.

Fox Providence’s The Rhode Show talk about recent unconfirmed shark sightings which close Westport’s Horseneck Beach. There are plenty of opinions going around on both sides of the argument The Rhode Show’s The Buzz ranging from the “Jaws scarred me for life” mentality to the “sharks are always in the ocean” mentality.

Horseneck Beach has been closed twice this week after shark sightings were reported. On Monday a shark was spotted by a fisherman. On Wednesday lifeguards spotted what “appeared to be a shark” less than 100m from shore. A decision will be made this morning on whether to re-open the beach after police and “shark experts” inspect the waters around the beach via helicopter.

The U.S. Coast Guard has issued a shark advisory for boaters in northeast waters.

The Associate Press is reporting that the Coast Guard has issued an advisory for boaters off northeast coast of the U.S. The article features several quotes from Al Johnson, the 1st Coast Guard District’s recreational boating specialist. There is no mention of Johnson’s expertise on white shark behavior, although the article does quote him on the subject. While Johnson does say that predation is generally not a concern for boaters and paddlers, he goes on to state…

“But I have no doubt that a great white shark that swims into your comfort zone would surely find a splashing paddle or dangling hand inviting. I also expect that same passing shark would spend little time differentiating between boater, paddler and prey.”

While it’s certainly prudent (for multiple reasons) to make boaters aware of the presence of white sharks in the area, the statements from Johnson seem to be a bit off-base. There are multiple first-hand accounts of people kayaking around large white sharks without the “splashing of a paddle” causing aggressive behavior from the sharks. The most well-known white shark encounters involving kayaks was documented by Michael Scholl and Thomas Peschak for Africa Geographic.

That being said, just because other people have kayaked with white sharks without incident does not necessarily mean that it’s something that is recommended for everybody to do. In fact, just last year there was a case of a kayak being bumped by a white shark in Australia that resulted in the kayaker being tossed into the water. The kayaker was unharmed and swam to a nearby boat.

However, to say there is “no doubt” that a shark would consider a dangling paddle “inviting” or spend little time differentiating between prey and a boater/paddler is a fairly bold statement. Research and observed behavior of white sharks has shown that white sharks can often be very discriminating about targeting prey during a predation event.

So, while Johnson does offer some sound advice to boaters on some levels, his rationale behind the advice is somewhat questionable, in my opinion. Should the public be aware that white sharks are in the area? Of course, but the information regarding the presence of these animals should not be accompanied by conjecture that seems to be in stark contrast to available research and observed behavior of white sharks.

At the end of the day, white sharks are large predatory animals, and from that respect a level of caution should always be taken in their presence, as there is certainly a level of danger associated with them. However, research has shown that they are also not the mindless attacking machines of horror movies and folklore who attack anything in sight. It is important for those who might encounter these animals to understand that, in order to avoid a panicked response, so that encounters can be addressed with common sense and level-headed thinking.

Here’s to a safe holiday weekend for all of those celebrating Independence Day this weekend, whether you be in the water or on the land.

The presence of white sharks in the Cape Cod area is expected again this summer.

Boston Globe columnist Brian McGrory’s “State’s little white lie” addresses what the author appears to believe is an attempt by Massachusetts state officials to downplay concern over the presence of great white sharks in the Cape Cod area. McGrory likens an announcement from Ian Bowles, state secretary of environmental affairs, and Dr. Gregory Skomal of Massachusetts Division of Marine Fisheries to the attempted cover-up of a shark attack by the fictional character, Mayor Vaughn, from the movie “Jaws.” The announcement from Bowles and Skomal informed the people of Massachusetts that there was nothing to fear from great white sharks in the area, when it comes to visiting Massachusetts beaches over the upcoming holiday weekend.

Clearly, McGrory does not agree with this statement, but he offers little in the way of any kind of scientific evidence as to why this announcement should be viewed with skepticism by the public, save for references to a Google search, regarding white shark births and information from Answers.com (which is a user-submitted wiki, often lacking any references) regarding the maternal nature of white sharks. The references to white shark births were included as a result of McGrory expressing concern over the young white shark that was tagged last week in Stellwagen Bank last week.

McGrory’s logic seems to be that if a young white shark is present in Massachusetts’ water, then there is potential for other white sharks, including the shark’s mother and possible siblings, to be in the same general area. While this line of thinking isn’t necessarily flawed, the idea that swimmers are at risk due to the sighting of a young white shark 20 miles off the coast could certainly be considered questionable.

McGrory’s piece is undoubtedly tongue-in-cheek at times, but the overall message is that he believes beach-goers in Massachusetts are in danger if they go swimming. McGrory seems fairly convinced of this danger to the point that he calls into question the sincerity of Dr. Greg Skomal and his stance on the safety of swimmers. McGrory goes so far as to pick apart the semantics of Skomal’s voicemail message which states his is “in the field,” to which McGrory remarks that he prefers his shark expert to be “in the water.”

While there are always going to be risks involved with going to the beach (and doing just about anything else in life), the scientific evidence suggests that the risk of an attack by a great white shark is relatively negligible. Obviously, the presence of a relatively large number of white sharks which are known to be feeding in a particular area will increase the odds of an attack if people are swimming in that area. In that respect, McGrory’s concerns over the dangers of white sharks are not completely unfounded. However, last year when a large number of sightings of white sharks were reported near Chatham beaches, the government did, in fact, recognize the increased risk and closed the affected beaches.

McGrory’s story seems to promote the idea that officials such as Bowles and Skomal are being irresponsible by informing the public that the beaches are safe, but the same argument could be made toward McGrory for suggesting (albeit sarcastically) that the officials are being disingenuous toward the public. McGrory doesn’t offer much evidence to support the implied dangers that he is trying to alert the reader to. The article implies McGrory’s knowledge of white sharks is limited to what he has seen in the movie “Jaws” and to what he has Googled. On the other hand, Dr. Skomal has a background studying marine life, including great white sharks and was on-hand and “in the field” (aka on the water) last year during the tagging process of some of these white sharks. To McGrory’s credit, he does state toward the end of his column that he can only speak for himself. However, he then goes on to urge everyone to stick to the miniature golf course over the holiday weekend.

At the end of the day, we all have to make our own decisions about the risks we take. I’ll be heading to a North Carolina beach next week not far from where a bull shark attack occurred last week. I’m more worried about being on the road with drunk drivers over the holiday weekend than I am about swimming with sharks. As Mr. McGrory said, I can only speak for myself.
