We had the OneShow film team for their yearly update on Scottish basking sharks with us last week and they are great to work with. They had the most amazing luck as the weather forecast was for force 7 at times, yet we not only found a number of basking sharks but the sun came out as well. Mauvis’s MSc student Holly Allan was with us to see the sharks and to learn how to take photo-id shots, having spent several months going through our photo-id catalogue looking for matches of the dorsal fins over time. Rupert found the decisive sharks for the sunny part of the filming, handling our boat Fairy Tern well in the rough waters. Nephew Austin was on board, not sure what to make of it all. SOSF Dan is coming up to film and is undecided about the cat Smudge that will be accompanying us on our surveys for basking shark next week.

Worldwide manta ray satellite tagging study

Posted by Andrea Marshall in Manta Rays, Mozambique Tags: , , ,

tag cutout copyThe Foundation for the Protection of Marine Megafauna has begun a worldwide study on the behaviour and migratory patterns of the newly-described giant manta ray (Manta birostris). Initial observations suggest that this species may be more migratory and oceanic than its smaller relative, the reef manta (Manta alfredi), which is typically resident to coastlines or island groups. To determine if the giants indeed travel great distances across oceans or along coastlines, Dr. Andrea Marshall, Dr. Simon Pierce and colleague Dr. Juerg Brunnschweiler sourced funding from the Save Our Seas Foundation to begin a worldwide study on their movement patterns. They hope to travel to several locations across the globe, teaming up with other local researchers or dive operators along the way.

Brazilian Manta Mystery

Posted by Andrea Marshall in Manta Rays, Mozambique Tags: , ,

giant manta dorsalSeasonal reports of giant manta rays from the small island of Laje de Santos off Brazil have led to an annual migration of scuba divers to the area to view these amazing creatures. There are no regular sightings of this species from anywhere else along the long Brazilian coastline, which leads to some intriguing questions: where do the mantas come from, and where they go when they leave this small marine protected area?

Deep Diving Mantas

Posted by Andrea Marshall in Manta Rays, Mozambique Tags: ,

Have you ever wondered how a manta ray spends it days? Scientists and divers only get a glimpse into these elusive animal’s lives when they encounter them at cleaning stations on shallow reefs. Despite increased research efforts in the last decade, scientists still know very little about the habits or daily routine of the world’s largest ray. In an effort to change all of this, researchers are now using cutting edge technology to uncover where these gentle giant’s go when they leave shallow coastal areas.Giant Manta (Manta birostris)

Maldives Manta Madness

My seaplane touched down at last light on August 14th 2009 settling on the choppy waters of Baa Atoll during a welcome lull in successive monsoon squalls. I can’t really think of a better birthday gift then returning to one of my favorite places on earth. Just over a year had passed since I last visited this northern corner of the Maldives to photograph a story on manta rays for the July 2009 issue of National Geographic Magazine. Hanifaru Island, situated at the atoll’s eastern edge is the home of the world’s largest manta ray feeding aggregation and became my most productive photo location of that expedition. Back then Hanifaru enjoyed no protection from fishing and was in danger of being overrun by well meaning tourists.

The foresightedness and environmental ethos of the newly elected Maldives government, the hard work of Save our Seas Foundation marine biologist Guy Stevens and National Geographic magazine’s ability to reach more than 50 million people around the globe has given Hanifaru’s manta rays and whale sharks a fighting chance to survive into perpetuity.
