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.
Thank you very much to everyone who contributed to the fish site throughout the year. Permission to use images and movies was granted by 87 people. I've compiled a short summary, below, of what you have made possible. So, thank you and best wishes for a happy, safe (and fishy) 2012.
We added some great new content this week and are excited to show images of a Monte Bello Seahorse. These may be the first underwater photos of the species.
As always, thank you to everyone who contributed and best wishes to all our 'fish friends' for the Festive Season.
Well technically speaking, it hasn't been a week. A few of the images below were added to the site before I went on leave, and a few have been added since I returned. Thank you as always to all who have contributed.
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 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.
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.
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.
