Giant Manta listed as Endangered
The conservation status of the giant (or oceanic) manta ray (Mobula birostris) has been uplisted today to Endangered on the International Union for the Conservation of Nature (IUCN) Red List of Threatened Species. An endangered listing is reserved for species with grave conservation concerns. Today’s announcement serves to confirm what we have long suspected – this gentle marine giant is finding it hard to cope with intensifying anthropogenic pressures around the globe. The giant manta ray now joins over 16,000 endangered species to be assessed with this serious threat level. At this stage, 30% of sharks and rays are now threatened with extinction.
The announcement marks the end of a devastating two decades for this species. Targeted for their gill plates – which they use to filter feed on small zooplankton from the water column – the unrelenting and increasing demand for their body parts has fueled both existing and emerging target fisheries. The relatively new Asian-based trade seems to be impacting the giant manta more than other species of manta ray, with the unsustainable harvesting decimating their populations across the globe.
Dr. Andrea Marshall, co-founder of the Marine Megafauna Foundation (MMF), who lead-authored this newest assessment for the IUCN, has been involved in their assessments since 2003. “The giant manta ray is a classic example of a species that is quickly succumbing to human-induced pressures. When we first assessed manta rays in 2003 there simply was not enough information on the species to determine their conservation status and they were listed as ‘Data Deficient’, but on each of the subsequent assessments, their conservation status increased steadily from Near-Threatened, to Vulnerable and now to Endangered. Their current status is a direct result of unsustainable pressure from fishing, which now threatens to destabilize their populations across the globe.”
To curb the burgeoning trade in their body parts to Asia and to encourage more comprehensive conservation strategies for their populations around the world, the giant manta ray was listed on two of the most important global conservation treaties, the Convention on Migratory Species (CMS) in 2011 and the Convention on the International Trade in Endangered Species (CITES) in 2013.
Sadly, their numbers have continued to decline. “Manta rays simply cannot withstand such pressures on their populations,” Dr. Marshall explains. “They have an extremely conservative reproductive strategy. They reach sexual maturity relatively late in life, they give birth to a single offspring every few years in the wild, they do not look after or defend their young and the offspring themselves are vulnerable when they are small and may not survive. In other words, as a species, they simply cannot reproduce fast enough to build back their numbers once they are depleted.”
This iconic species is not only extremely important from an ecological perspective, giant mantas also provide vast economic benefits to tourism industries around the world. “Interactions with manta rays are highly sought after by dive and snorkel tourists globally and contribute millions of dollars to tourism economies each year, particularly in developing nations. At this pivotal time, recognizing their economic value may help to encourage the protection of this enigmatic and now endangered species” explained Dr. Stephanie Venables, a Senior Scientist and manta ray expert at MMF.
The giant manta ray was only formally described (the process of gathering enough scientific evidence to provide a taxonomic description of a newly discovered species) by Dr. Marshall and colleagues in 2009. At the time it was one of the largest species to be described in our oceans and the announcement was met with excitement around the globe. The discovery was covered by the BBC that year in the first-ever documentary on manta rays.
“It is such an honor to have been able to study and describe this species. The realization that the giant manta ray is now in danger of extinction is a hard pill to swallow”, Dr. Marshall admits. “We are still busy learning about this extraordinary creature and we have only scratched the surface. There is so much more we need to understand, but at this stage, we have put that all aside in favor of protecting the last remaining populations of giant mantas across the globe.”

Shark Trust launches Oceanic 31 Shark Art Auction
After a two-year tour of UK art galleries, community spaces and aquariums, the Shark Trust’s acclaimed Oceanic31 exhibition takes its final bow at the Royal Geographical Society later this month. And the unique collection of artwork, depicting 31 species of oceanic sharks and rays, donated by 31 artists, is now open for bids from art lovers and shark enthusiasts. The online auction, launched today, will close on the 7th December at 8pm (BST). The money raised will support the Shark Trust Oceanics Programme.
People can now bid on 27 of the artworks by visiting this website:

You can pick your favourite artist or species of shark. Or you can select the perfect artwork to make a statement in your home or office. Whichever you choose, you will be supporting the work to protect these amazing animals.
One of the pieces of art has been selected to be auctioned live by Steve Backshall at the For the Love of Sharks event at the Royal Geographical Society in London on the 29th November. In addition to this, two further pieces will be raffled at this event, giving people a chance to win an incredible piece of shark art. For the Love of Sharks is the Shark Trust’s flagship evening. A night to celebrate sharks. Steve Backshall is the headline speaker at this event that will see other prominent shark advocates join him on stage.

On top of that, some of the most admired companies in the diving and scuba industry have been quick to support the charity with fabulous prizes that make the £5 ticket price worth more than just a flutter.
Master Liveaboards, BSAC, Midlands Diving Chamber, Go Freediving and Blue Shark Snorkel have all generously donated experience prizes, while celebrated photographer Alex Mustard has donated a print and artists Scott Gleed and Olivier Leger have donated a sculpture and illustration to help boost the fundraising pot.
Fourth Element has donated Ocean Positive gear and LA watch company Nodus has gifted the charity a stunning dive watch. For land lovers, the charity has included a five star London hotel stay at Bankside Hotel plus a family visit to Longleat Safari Park in the roster of prizes.
Campaign director for Bite-Back, Graham Buckingham, said: “We’ve been overwhelmed with support from companies and individuals that we truly admire and who have supported us on our 20 year journey and we’re truly grateful to them all. While we feel incredibly proud of our achievements over the past two decades – and we are super excited about the next chapter – this prize draw isn’t a vanity project. It represents a real lifeline to our work and important advancements in the global protection of sharks. So we hope divers, dive clubs and even bargain hunters grab some tickets to make this a massive success.”
The charity hopes that the prize draw will generate crucial funds to launch a brand new, ground-breaking, campaign to enrol the public and increase support for the protection of sharks around the world.
