Energetic creatures, these sea lions are contributing to the recently developed national Integrated Marine Observing System (IMOS), which employs oceanographic instrumentation on ships, moorings and buoys to map and monitor the marine environment right around Australia.

X-ray vision: fish inside out

An exhibition at the Australian National Maritime Museum in Sydney features unusual images captured with a digital radiographic machine and arranged in an evolutionary sequence. Smithsonian National Museum of Natural History fish curator Sandra Raredon captured the images of thousands of fish specimens. All up, the institution, in Washington DC, has four million individual specimens representing 70 per cent of total fish diversity. The X-rays allow scientists to document internal features without ruining specimens, but they also make for unusual abstract artworks. The exhibition will be open until February 2016.
