Video of 5-year-old girl swimming with sharks draws criticism

A video posted by YouTube user elanajoy86, Elena Barnes, has created a stir of online criticism after the video went “viral.” The video documents a snorkel off Nassau, Bahamas in the presence of a variety of species of sharks common to the area. According to the video information, the drift snorkel took place in the presence of lemon sharks (Negaprion brevirostris), nurse sharks (Ginglymostoma cirratum), and Caribbean reef sharks (Carcharhinus perezii). Barnes describes the different species as “all very low on the aggression index.”

The criticism arose due to the fact that Barnes’ 5-year-old daughter also took part in the swim. Accusations (primarily in the form of blogs and YouTube comments) of irresponsible parenting due to the fact that a child is swimming in the presence of sharks. Barnes has since disabled comments on YouTube but notes in the video description that she appreciates those who are “greatly concerned” about her daughters well-being. She defended her and her husband’s decision to allow their daughter to participate in the swim and noted that her daughter was under constant supervision throughout the experience.

Barnes seems to have no regrets about the experience, despite some of the negative online backlash, and she even concludes the video description on YouTube by recommending the experience to others.

Research on the effect of ecotourism on tiger shark behavior

A team of University of Miami researchers, including shark researcher Neil Hammerschlag, have conducted a study using satellite telemetry on tiger sharks (Galeocerdo cuvier) in an attempt to learn what kind of impact ecotourism (in this case, baited shark dives) has on the shark’s long-range migration and habitat utilization.

Sample groups were taken from Florida (where baited shark dives are illegal) and the Bahamas (where baited shark dives are abundant). Analysis of the data from each sample group did not produce a significant difference in the measures of movement and behavior evaluated by the study. Additionally, the data revealed information about long-range migration behavior among both sample groups that was previously unknown.

An overview of the research is available at Functional Ecology.

Video: Lemon sharks of Bimini from Grant Johnson

Grant Johnson recently uploaded another shark-filled video to his YouTube channel. This one focuses on the lemon shark (Negaprion brevirostris) and was filmed off of Bimini, Bahamas.

Discovery News feature on recent shark conservation measures

Discovery Networks recently uploaded the video above to their YouTube channel which focuses on recently passed legislation in Chile, Honduras, and the Bahamas that helps to protect sharks within those countries’ waters. Honduras and the Bahamas have recently banned commercial fishing making their waters a “shark sanctuary,” while Chile has banned the practice of shark finning.
