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.
