Whale sharks are filter feeders and have long been observed eating krill at Western Australia’s Ningaloo Reef. But when researchers analyzed biopsy samples from whale sharks at the reef, they discovered the animals were actually eating a lot of plant material. […] CSIRO Oceans and Atmosphere organic biogeochemist Dr. Andy Revill, who analyzed the whale shark tissue using compound-specific stable isotope analysis, said the technology allowed scientists to study what animals were using for energy and growth, not just what they were eating.
