Exciting happenings this week include a small shark with a big appetite, drummers with weird buoyancy devices and a Sydney Harbour surprise.

The first happening of note is a small shark with a gutful.  Mike Miller sent great images of this fish from a research vessel in the Pacific.  Closer to home, Chad Loxsom's image of a Yellowfin Tuna renders the Sydney Harbour fish species list in our paper  'out of date' less than a month after publication... sigh!  And finally, Pat Plunkett from DPI Fisheries sent us specimens of two species of drummer for identification.  Their gas bladders are worth a look.
