The IPFC8 over, and number 9 probably located to Japan in 2011, it is soon time to bid farewell to Australia. Not much of fishes have we seen, but the Sydney Aquarium was interesting and had many fishes on exhibit both salt and fresh. I got my first closeup of a dugong, the real mermaid.

The local mall also had a nice assortment and tonight we dined on Macquairia maccullochi (hope I get this right because it is not easy to spell or remember) which was excellent. All the fish and chips and the fishburger in Pemberton were delicious but I am not sure what species is involved.

Saturday and Sunday I was invited by Heiko Bleher, famous in the aquarium world for travelling everywhere in the world in search of interesting freshwater fishes, to come along on a trip to photograph Lepidogalaxias salamandroides.

We had a nice journey from Fremantle south, guided by a map with likely localities already marked. Lepidogalaxias salamandroides is a very special fish. It is the only fish that can turn its head in different directions, just like humans can move the head relative to the neck. In the fish, this is accomplished by an extended distance between the anterior vertebrae, providing room for muscle movements otherwise impeded by the relatively stiff normal fish vertebral column. It is confined to, but not uncommon in a relatively narrow stretch of coastline in southwestern Western Australia, and more precisely to swamp regions that dry out in the summer, and carry water only in the winter. The fish aestivates buried in the ground, and comes out only when it rains. Generally in is the only species in the pools where it is found, along with some freshwater crayfish.

And, yes, we were quite successful in finding the salamander fish, south of Northcliffe (population 200, in the middle of nowhere), where it was in all roadside pools, over white sand bottom, in clear, red-coloured water, with a typical vegetation I do not know to name. In one place we found it together with Galaxiella nigrostriata, which is also a small species, but probably not able to aestivate. Heiko will make available images and detailed information elsewhere, in the meantime enjoy the exclusive habitat of the species.

PS. No, it was Maccullochella macquariensis, locally called trout cod, difficult to spell in any case, and maybe should not have eaten because it is an endangered species, something I now have come to know.
