Bye bye Manta Rays?

From the paper - click for detail!
It sure looks so - at least taxonomically!

Check this out.
It postulates what has been rumored for quite a while, i.e. that genetically, the Mantas belong to the Mobulas and that consequently,  their Genus needs to be changed from Manta to Mobula. The paper also does away with three species of Mobula (eregoodootenkee, japanica and rochebrunei) that are being subsumed under Mobula kuhlii, M. mobular and M. hypostoma, respectively, thus reducing the total number of Mobula species to eight. 
This does not necessarily affect the common names = we can still continue calling Mobula alfredi the Reef Manta, and Mobula birostris, the Giant (and/or Pelagic or Oceanic) Manta!

And would this be the last of it?
Considering the obvious morphological differences (= e.g. terminal vs sub-terminal mouths, shape of the cephalic lobes etc) but also the emotional attachment to the Mantas by so many folks out there, methinks most likely not - but with Will and Gavin being the current titans of Elasmobranch taxonomy, any detractors better come well prepared!

To be continued no doubt.
Really looking forward to a good frothy brawl - and if the past is any indication, we can all look forward to some epic fireworks! :)

No more Galapusky - Paper!


Or is it, Duskapagos?

Anyway, check this out.
I was sent to me by the Saffron Pimpernel under the heading of mumbo jumbo - and for a genetic ignoramus like me, it sure very much is! 
But having double checked with my trusted geneticist, she confirms that Gavin and Will's putative lumping of the Dusky and the Galapagos is no more, meaning that the two species continue to be valid.

Likely not a Dusky (see the map at the top) but a Silky like first assumed!
Ain't taxonomy fun - and it's so easy, too!:)

New Fantail Ray!


And I cite,
Taeniura lessoni sp. nov. is the second species in a genus containing the widely-distributed T. lymma, which is possibly the most abundant stingray in shallow coral-reef habitats of the Indo–Pacific, with the new species apparently restricted to Melanesia. Taeniura lessoni sp. nov. is distinguishable by the absence of a distinctive pair of vivid blue longitudinal stripes on the dorsolateral edges of the tail which is one of the most distinctive features of T. lymma.
And here it is on Shark Reef - 03:17.
Enjoy!
