The Dorsal Fin

The Sun Sentinel is reporting that George Burgess, Florida Program for Shark Research Director, has determined that the species involved in yesterday’s fatal shark attack off Stuart Beach, FL was a member of the requiem family, which includes tiger sharks, bull sharks, blacktip sharks, and spinner sharks. Burgess examined the bite wounds on the victim and determined that an 8-9′ shark of the requiem family was responsible for the two fatal wounds. Burgess said his examination definitively ruled out the great white shark, a member of the Lamnidae family.

Another media outlet has their own great white shark related report regarding yesterday’s tragic attack off of Stuart, Florida. This one is has an even more misrepresentative headline than the Palm Beach Post “report” from earlier today. CBS12.com features a story with the headline, Expert: Great White Shark could have been behind fatal attack. The report features statements from Gary Gross, a biology professor at Palm Beach Atlantic University, who is quoted as saying, “Great whites in our area are very uncommon. They are mostly in deep waters where it’s colder. There has never been an attack here by a white shark.” In fact, the only other mention of white sharks by Professor Gross in the report deals with large sharks mistaking a kite surfer for a turtle, in which Gross is quoted as saying such a scenario is a “white shark situation.” However, Gross goes on to speculate that the attacking shark was “likely a bull shark.” (Currently, there is also no evidence to support or oppose the theory that the sharks involved in the attack were bull sharks.)

CBS12 really seems to be stretching things here. The headline suggests that Gross has indicated that he believes a white shark could be behind yesterday’s attack. However, the statements from Gross within the article suggest that he does not think that great white sharks were involved. Perhaps, a more representative headline would have read, Expert: Highly unlikely great white shark involved in attack. Of course, that might not draw nearly as much attention. It seems that media outlets have realized that great white sharks seem to draw more attention than other shark species, and the mass number of stories running with the great white shark theory (which isn’t backed up by any evidence in this particular case) just goes to show that sometimes the number of viewers/readers a story draws can overshadow truly objective reporting.

At the end of the day experts weighing in on the species involved or not involved is still nothing more than speculation, until some more details and evidence regarding the attack is available.

The Palm Beach Post has a cleverly crafted article with a headline “possibly” identifying the species involved in yesterday’s fatal shark attack of a Stuart, Florida kite boarder. The headline, Expert: Young great white sharks possibly involved in fatal Stuart attack, is followed up with the statement credited to Grant Gilmore noting that “young great white sharks — the fish of Jaws notoriety — are among suspects in Wednesday’s fatal attack off Stuart’s coast.” However, if you read far enough into the article, it states that Gilmore would NOT guess which species was involved, since the only available information about the attack was early news reports.

The article goes on to discuss yesterday’s shark attack and mentions three other species common to the area that are cited as being “known to attack humans” but notes that these three species (bull sharks, tiger sharks, and great hammerhead sharks) prefer warmer waters and tend to leave the area in the winter.

Despite the tendency for these species to leave the area in the winter, tiger shark sightings were reported just last week at Riviera Beach, approximately 35 miles north of yesterday’s attack. In addition, a shark which at least one news source identified as a great hammerhead, was also caught on Riviera Beach last week. That same report indicates that bull sharks are common in the area this time of year.

While there is nothing dishonest, per se, about the story’s headline identifying a “possible” suspected species, the nudging of the reader towards the idea that great white sharks (“of Jaws notoriety,” no less) were behind the attack is fairly prominent, despite no evidence being available at the time of the report to indicate the species. So, while the article is not necessarily dishonest, I find it a bit misleading at best. Other news agencies are eating up the Palm Beach Post article and running their own similar stories, including the LA Times article,
Young great white sharks may have killed Stuart surfer, expert says.

While it may turn out that great white sharks were, in fact, involved in this tragic attack, running headlines based on a few statements suggesting a possibility that great white sharks were the culprits is simply irresponsible reporting. Given the limited information that was available when the statements were made, speculation by news agencies falls outside of the realm of objective reporting, and is irresponsible journalism, at best, especially considering the fact that the expert who was questioned on the subject specifically stated that there was not enough information to even guess the species.

The Brisbane Times is reporting that the Queensland government will be spending $125,000 on a five-year program to tag and monitor bull, tiger, and white sharks in an effort to "reduce the risk of attacks." Acoustic tags will be used to report data to monitoring stations when tagged sharks are nearby. Shark control program manager, Tony Ham, said that they expected to tag 150 sharks in three years (which seems like an odd statement, considering that the article reports the duration of the study to be five years).

In addition to the shark monitoring aspect, the Queensland government will also invest in new and improved acoustic alarms to alert whales and dolphins of the existence of shark nets." The new alarms will use a longer lower pitch signal at a louder volume to give cetaceans a more advanced warning of the nets. The shark nets have come under criticism due to whales and other marine life becoming entangled in them.

Oceanfootage.com has posted a "highlight reel" which features a compilation of clips from some of their available stock footage. The video showcases some wonderful footage of a wide variety of shark species (including the great white shark, scalloped hammerhead shark, bull shark, basking shark, and sand tiger shark to name a few).
