Project Leader: Andrea Marshall
Manta Rays, Mozambique

The International Union for the Conservation of Nature (IUCN) currently lists manta rays (Manta birostris) as ‘near threatened’. It’s known that several populations around the world are severely depleted, but not enough scientific work has been carried out to properly assess the species as a whole. Almost nothing is known about their population ecology, use of critical habitat, movements or reproduction, all of which are vital in order to accurately assess the state of the species.

As part of project leader Andrea Marshall’s PhD thesis for the University of Queensland, SOSF is currently funding a five-year project in Mozambique to enable her to carry out a unique in-depth study of the biology and behaviour of manta rays.

Researchers have discovered a previously unknown species of manta ray. Previously there was believed to be only a single species of ray but genetic analysis now shows there are at least two, and possibly three, species.


Dr. Andrea Marshall

The research, carried out by Andrea Marshall, a marine biologist sponsored by the Save Our Seas Foundation, distinguishes a larger and rarer type of manta as a new species. The species can reach a weight of 4500 pounds (2 metric tons) with a pectoral fins "windspan" of 26 feet (8 m). It appears to be more migratory and elusive, than its smaller, more common cousin.

Manta rays are the largest of over 500 different species of rays and skates. Unlike stingrays, manta rays are harmless and do not possess a stinging barb. They feed on plankton.

Rays are commonly harvested for foot markets, especially in Asia, but also suffer as bycatch. As a result, populations are declining in some regions.

I dived with Andrea in Tofo while staying at Casa Barry Lodge, This woman is truly amazing in what she is doing for Manta Rays in Mozambique. If you ever go to Mozambique you need to try and meet this woman, maybe you might get lucky enough to get a dive in with her and the Mantas.
