The Dorsal Fin

The latest pro-shark video from Blue Sphere Media and WildAid features Richard Branson swimming with whale sharks (Rhincodon typus) off of Mexico’s Isla Mujeres in order to raise awareness about protection of the species. Isla Mujeres has become a well-known aggregation point for whale sharks in the summer months, where hundreds of whale sharks gather each year to feed in the area’s nutrient rich waters.

While Branson refers to whale sharks as an “endangered species,” it should be noted that the IUCN actually list the species as “vulnerable” on the Red List, which is the next category below “endangered.”

Branson also tends to focus on the sharks being the victims of finning. However, the whale shark has been targeted in the past not only for its fins but also its meat and massive internal organs. For example, a recent feature on whale sharks in Kenya noted that the liver from a whale shark is a valuable commodity to fishermen. The IUCN also notes that whale shark populations have been depleted in some areas by harpoon fisheries and unintentional capture (or bycatch) by traditional fisheries.

A pirated version of Blue Sphere Media’s Unnatural Selection – Shark Finning on the Frontier video recently popped up over on YouTube. I hadn’t seen this video before, so I tracked the original down through Blue Sphere Media’s website and their Vimeo channel. The video seen below features some powerful imagery of finned sharks. From a production standpoint, the video gets an A+. Unfortunately, the video suffers from “magic number syndrome” (both the “100 million” and “90% decline” estimates make appearances in the video). The footage in the video alone is enough to make a strong message about shark finning, but when accompanied by “statistics” that have no scientific evidence behind them, the message becomes diluted. The problem of shark finning is real, as evidenced by the footage in the video, so why not use some “real” numbers (not to be confused with the real numbers you learned about in 5th grade during Mrs. Walker’s math class) to accompany this footage?

Warning: Video contains footage of discarded finned shark carcasses and severed shark fins.
