Distribution
C. caspia is native to brackish and fresh water habitats around the Black Sea and Caspian Sea. From there it has spread, on the hulls of ships or by some other means, via channels and inland waterways to most of the temperate and tropical world.[1] It arrived in the Baltic Sea in the early nineteenth century and spread rapidly to the estuaries and inland waterways of Western Europe, reaching Ireland by 1842. By 1885 it had made its way to Australia and by 1944 to Panama. It has not reached Antarctica.[2]
gollark: ↓ you
gollark: As can be seen, I have demolished all objections and thus am right.
gollark: This can be shown to be valid:
gollark: I CLEARLY said `= (maybe)`.
gollark: However, apiohax = P = (maybe) NP = 0 (mod N). Therefore, as rings may be noncommutative, it is the case that the left ideal, 7, is an eigenvalue of the matrix expansion of the general bee formula. By basic applications of previously proven lemmas, it can be shown that this makes apiohax isomorphic to the group (ℤ, +). The implications are obvious.
