Edy Setyawan, PhD in manta rays, grew up in a small mountain village in Java. Today, he stands among the world’s leading researchers on manta rays and sharks. He has published a remarkable body of scientific work, co-founded an Indonesian-led NGO dedicated to elasmobranch conservation, and was the first to conclusively identify a manta ray nursery habitat in Wayag, Raja Ampat – along with multiple other potential nursery locations throughout Raja Ampat.
Sharks and rays have long been considered "silent" fish - that is, unable to produce sound. Researchers from Sweden and Australia have now shown that this is a misconception, writes SLU (Swedish University of Agricultural Sciences) in a press release.
