Fish mimicking octopus mimicking fish!

The Mimic Octopus (Thaumoctopus mimicus) has been known for some years for its ability to mimic flatfish, lionfish and seasnakes.  A recent discovery in Indonesia adds a whole new twist to this story.  The Black-marble Jawfish (Stalix cf. histrio) mimics the Mimic Octopus. This is believed to allow the small fish to forage in relative safety well away from its burrow.

This week in Fish: Murray Cod Movie

This week we show movies taken at depths of 4 m and 2400 m.  The first movie shows what may be the first footage ever taken of a Murray Cod guarding its eggs in a dam.  The second movie shows a Threadfin Seasnail swimming down a deep rocky slope.  As always there are also some great images.  Thank you to everyone who contributed.

This week in Fish: Hagfishes - masters of defence

This week we show remarkable footage of hagfish using slime as a defence mechanism.  These fishes are also active hunters.  There are some great new images, plus the first sighting of 'the' undescribed anglerfish guarding its eggs.

Amazing new hagfish behaviour

Hagfishes are incredible! They can stop a would-be predator within seconds with a mouthful of slime. Ichthyologists at the National Museum of New Zealand (Te Papa Tongarewa) have just published a fascinating paper on hagfish behaviour in the journal Nature.

This week in Fish: Dani, Fanny and Emperors

As usual, there are some great new images and movies to view.  Watch a whiptail swimming over 1 km below the surface and an oh-so-cute Pacific Leaping Blenny feeding on the rocks.  We welcome Fanny deBusserolles who is working on lanternfishes for a fortnight and Dani Fox who is processing specimens collected during the Kermadec Islands Expedition.  Thank you very much, as always, to all our contributors.
