If this isnt a Constellarta

[andersp90]

The 1st pic is not a constellata, but just a big ray with small denticles.. Frank has a Motoro with that situation..

The 2nd pic looks like a constellata, because of the denticles

Not sure if it's a disease or not but I do believe it's classified scientifically as a distinct species..

First and 2end pic is the same fish.. The light is just more bright on the 2nd photo.. Its an sp. type. I have seen them before at my local LFS.. Think they are from Columbia.. But the one Bruce has pics of and the one i have posted have the same type of bumps denticles or what ever.. So they are defiantly not the same species..
So it must be some sort of disease.. And not a species.. Not those anyway..

I think they are both constellata then

Could be a disease.. could also be a product of hybridization.. A motoro that produces denticles might have a little constellata in it.

I would say rather than a disease, it would be a product of too much calcium in the water or something similar.. BUT, it occurs in the wild so I don't think so.

I think it would be hard for ichthyologists to confuse morphological differences with diseases..

i don't think its a disease
my ray only has them on her tail area but they look just like the chocolate kiss denticles that we are looking at
i still think mine is a mossiac it hard to say

I think that they are many rays that will develop denticles with age/maturity- I've seen them on motoro.

We have a big motor too with denacles.

Very true I have a male pearl ray with denticles on the tail area. Does that make it a constellata? NO

Good, so lets all agree that none of the fish shown in this thread is a real constellata, IF there are any at all..

Its a dried out ray with denticles.. It could be anything.. And its sounds like any ray could develop these denticles.. And that’s prob all there is to it.. Dr. roos thought the mantilla ray was a new species.. but we now know its just a hybrid.. I’m sure its the same thing here.. Some bloke picked up a ray with denticles an thourght "hey! i just found a new species because it has denticles, lets name it constellata". So constellata should be used as a term to describe rays with denticles..

All the rays that i have seen, on german forums, that has been discribed as constellata had spots.. Not stripes/rings like yours.. Its not a constellata..

The constellata is down the page on link 3.. But they all have spots.. Though constellata is just a name.. Could be anything..

wrong again little boy
