Why is there any reason at all to think that the current distribution of species around the world is optimum or even equilibrium?
We have knowledge of the distribution of species over only a very short time, and it is ludicrous to think this is the way it always has been. In fact, we know for certain that the current distribution is not the same as it was even a few centuries ago.
This isn't bad, it is just the way things happen.
I would think, genetically, these tigers (?the ‘tiger’ shrimp I’ve seen for sale in TX are always blue, not black)
would have an impossible time burrowing into the sandy GOM bottom as our pink, white and brown ones do to escape predators.
I wonder if the lack of hurricanes in the GOM has anything to do with their being populous enough to catch.
How they got here? Water in hatches from ships coming West carried the larvae, I suppose, as I think all shrimp breed in estuaries. That’s what we were taught, anyhow.
I think this tiger has enough bad things going for it, like me, who’d scoop them up if they became commercially available here.
