This week we feature a great movie clip of two Numbfish up close and personal. Alan Williams from CSIRO Hobart visited to work on lanternfishes. As usual there are plenty of new fish images. Thanks to all.
Among other great images, we have posted photos of the eyes of a Longhead Flathead and a Smalltooth Flounder. The images were not taken with fish eye lenses :).
Nearly all species of fishes have eyes, but some don't. We've provided some links to information on blind fishes plus one link to an Australian species that is blind-in-name-only.
"Sawfish seen in action" might sound more grammatically correct than "Sawfish saw in action", but if you click on the link below you'll see why I've given the blog post that name. Thank you as always to everyone who contributed images and comments during the week.
This movie clip shows a sawfish feeding.
Sawfishes can slash from side to side with the rostrum to stun, impale or even cut prey fishes in half. The rostrum can also pin fishes to the substrate where they are ingested.
Fishes of the genus Liopropoma have have extremely long ornate second and third dorsal fin spines during their pelagic larval phase. This ornamentation is lost when the larvae metamophose during the transition between open water habitat and the reefs where Liopropoma species live as adults.
This week we posted images of a strange mullet with elongated fins. This is not the first image of a strange 'fan-finned' mullet that has been sent to the museum. We also show an image of a rarely reported dartfish from Sydney Harbour.
Dr Zoe Richards has just returned from an expedition to Kosrae, Micronesia, where she was surveying coral biodiversity. In this post, she describes her scuba diving surveys beneath the Island of the Sleeping Lady.
