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.

Threadfin Seasnail swimming at 2400 m!

This impressive movie was taken at a depth of 2400 m.  The fish is a Threadfin Seasnail, Rhodichthys regina (family Liparidae).  Thank you to Dr David Stein for identifying the fish.

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.

This week in Fish: Bastard Trumpeter and Childish Pearleye

This week we were visited by Adrian Flynn, who worked with John Paxton on specimens of Dana Lanternfish.  We posted an image of the strangely-named Bastard Trumpeter and saw the addition of an image of a Childish Pearleye - a new family for the site.  Thank you to all who contributed!

This week in Fish: First Kidako Moray image

This week sees the addition of some great new movies.  The Halfband Snake Eel descending backwards into the sand is pretty amazing.  The Lepidion swimming at over a kilometre below the surface is worth a look and the male Pacific Leaping Blenny 'frantically' trying to attract females certainly brought a smile to my face.  There are also some great new images.  What is possibly the first photo of a live Kidako Moray and the oh-so-cute baby boxfish are just two of a great bunch.  Thank you to everyone who contributed.

This week in Fish: Vale - Dr Robert McDowall

This week we celebrate the life of the late Robert (Bob) McDowall, a giant in the New Zealand fish world.  We follow a juvenile chimaera swimming more than 1200 m below the surface.  There are plenty of new images, including shots of a moray eel that lives in freshwater and the amusingly-named 'Velvet Leatherjacket'.  Thanks as always to everyone who contributed.

This week in Fish: Martin and Carl visiting

It has been a busy week.  Two visiting researchers arrived on Monday.  They are examining morid cods in the ichthyology collection for the next fortnight.  We added another image of juvenile Roundface Batfish in Sydney, and bathed in a wealth of new fish images.  Thank you to all who contributed.

This week in Fish: Incredible! A new fish family.

It's a special week.  A new fish family has been discovered.  You can view a movie of this primitive eel that lives in a dark cave at the base of a coral reef in Palau.  Of course, there are plenty of other great images to check out.  Thank you very much, as always, to everyone who contributed.

'Living fossil' eel in an undersea cave

Dr Dave Johnson from the US National Museum in Washington just emailed me about an incredible eel that he and colleagues recently described.  The fish, Protanguilla palau, is now classified in a new family, the Protanguillidae.  It is one of the oldest eels (in evolutionary terms) known.
