And now, for something entirely different… a brief respite from the oil spill madness. A reminder of the beauty of the seas from Oceana scientist Margot Stiles. - Emily
Every spring Belize hosts one of nature’s great wonders: the arrival of whale sharks in search of spawning snapper. This year I had the pleasure of witnessing it first hand, on last month’s Oceana expedition.
The whale shark is the largest fish in the sea at 60 feet long, but it is mild-mannered and harmless to people. Around the full moons of March through June each year, whale sharks arrive and begin feeding at the Gladden Spit and Silk Cayes Marine Reserve near Placencia, Belize.
Tony Rath of Naturalight Productions has spent thirty years photographing wildlife in Belize and still beams at the mention of his most recent expedition with Oceana. “Seeing whale sharks this close is an unforgettable experience, as inspiring as seeing a puma or any of the large animals on land,” he said.
I couldn’t agree more. Despite hundreds of dives around the world, I found swimming side-by-side with a whale shark truly sublime, a transcendent moment I’ll look back on for many years to come.
This is the ninth in a series of posts about the 2010 Ocean Hero finalists.
The Shark Finatics are a group of students at Green Chimneys School in Brewster, New York. Green Chimneys is renowned for helping emotionally injured children through animal-assisted therapy.
Teacher Robin Culler has worked in the Speech Department for over 11 years. When she read a book about sharks aloud to her students, they were horrified to learn about the brutal practice of shark finning and vowed to tell as many people as they could.
The students, who soon became known as the Shark Finatics, decided to "adopt" a shark. They helped make shark magnets to raise money for their first shark, Jonny, from Fox Shark Research. In 2009, they were proud adoptive parents to 21 sharks.
Through various projects, they have raised more than $2,000 for shark research and conservation organizations around the world. And they have reached out to hundreds of people about the threats facing sharks.
I recently got some very heartening news here at Oceana from some of our youngest supporters.
The seventh and second grade students at Good Shepherd Episcopal School in Dallas, Texas were inspired by our “Scared for Sharks” campaign and raised more than $2,500 for Oceana through a week of bake sales and a “Caring Color Day,” where students wore blue and gray "shark colors" and donated $2 each.
It was especially nice to hear this news in light of the recent decision by CITES not to protect endangered marine species, including sharks.
Of course, Oceana is still moving forward to protect sharks around the world. We’ve already helped the United States become a leader in shark protections, and we’re continuing to push the U.S. to put a final end to shark finning, the brutal fishing practice that is responsible for tens of millions of shark deaths every year.
We’ll use the donation from the students of Good Shepherd to continue to fight to save sharks. You can help today, too, by donating or asking your senators to support legislation that ends shark finning.
Andy Sharpless is the CEO of Oceana.
This is the seventh in a series of posts from CITES. Check out the rest of the dispatches from Doha here.
Eight shark species have been proposed for listing to Appendix II of CITES, including the oceanic whitetip, scalloped hammerhead, dusky, sandbar, smooth hammerhead, great hammerhead, porbeagle and spiny dogfish.
Listing these species, which are threatened by shark finning, is necessary to ensure international trade does not drive these shark species to extinction.
Here's Oceana's Ann Schroeer from our Brussels office with an optimistic outlook on the upcoming shark proposals at CITES.
A study in the Journal of Experimental Biology made big news late last year by beginning to answer a fundamental, fable-like question: why are hammerhead sharks shaped the way they are? The answer, as it turns out? The better to see their prey with, my dear.
The researchers found some surprising results about hammerhead vision. One of those researchers, Michelle "Mikki" McComb of Florida Atlantic University, happens to also be an enthusiastic Oceana supporter. Mikki was kind enough to answer some questions about the research:
Can you summarize the conclusions you and your colleagues reached about hammerhead vision?
The popular literature is filled with claims that hammerheads have better vision, but this was never tested. Our goal was to quantify the extent of the visual fields of hammerhead sharks in contrast to more typical head shaped sharks, in order to determine if they possessed binocular vision.
The visual field is the entire expanse of space visible around the head and can be described by one eyes field of view (monocular field), two eyes field (cyclopean) and the overlap of the two monocular fields (binocular overlap). We determined the horizontal and vertical visual fields of three hammerhead shark species as well two closely related “typical” shaped sharks.
What we found was a surprise! Hammerhead sharks do have binocular vision, and even more surprising, the extent of binocular overlaps was greater than found in the “typical” shaped sharks. The largest binocular overlap was found in the winghead shark, the hammerhead with the widest head, and is a result of the positioning of the eyes on the end of the head.
