Thought you guys would like this, if you haven't already seen it.

Posted in the new taxa thread (http://www.monsterfishkeepers.com/forums/showthread.php?t=114699&highlight=erythromycter&page=19) but I know many of you shark people don't go outside of the salt area too much... thought this deserved it's own thread anyway.

20 new species of sharks described... All are from 'Descriptions of New Australian Chondorichthyans' (http://www.cmar.csiro.au/e-print/open/cmar_rp022.pdf) and for those who don't want to browse the 368 page pdf :eek:, here are the pics...

In order (some are paratypes, holotypes, preserved and not etc.):

Glyphis garricki - freshly caught


This Glyphis garricki is known as a rivershark. Does this mean they live a large portion of their lives in the river, or simply they are found their occasionally, although live in the sea in the most part? Cheers.
 
Yup and to think thats just in Aussie not to mention how many more that are still undiscovered. Can you imagine how many sharks in the world there are that we have never seen or recorded? It doesn't mean there isn't a huge decline in population though and how many species are extinct that we may never have known about.

scary bit isn't it!

I think my favourite is either the wobbegong or some of the swellsharks (C. hiscosellum in particular, what an attractive species)
 
In some cases - newly identified species - were previously misidentified as a juvenile or adult of another species.

In other cases - it maybe that they simply weren't known to science until very recently.
 
Yeah, there are plenty that have been well known but only just recieved a name of their own.

May I add, there are also quite a few other fish in this paper... stingrays mostly and a flatfish or two.

One question what is the difference between a stingray and a stingaree? The stingarees I noticed were smaller... is that all?
 
Thanks for sharing Davo. Any word on a hard copy publication yet. The application just about overloaded my computer. lol
