distribution map

The distributionmap is wrong. see the following links.

Fishlist of the Black Sea: http://www.blacksea-commission.org/Misc/FishList.htm

"There are two species of sharks in the Black Sea - fortunately small and completely harmless." http://www.un.int/russia/new/MainRoot/newrussiaen/bscaucasen.htm

"Apart from the Bottlenose and other species of dolphin, the sea has about 180 species of fish, including flounder, sea dragon, sea scorpion, mackerel, and the famous Black Sea shark." http://www.divematrix.com/showthread.php?t=3282

"Sogar Haie kommen in den ukrainischen Gewässern vor, allerdings handelt es sich hierbei um kleine Dornhaie, die für den Menschen ungefährlich sind". (Even sharks are common in ukrainian waters, but only Spiny dogfishs which are harmless for humans.) http://www.goruma.de/Laender/Europa/Ukraine/Wissenswertes/Tiere.html

also look here (taken from this source of the article).

Are you really sure that the threaher is common in the black sea?

I didn't make the distribution map, but I believe it's based off of the map in Compagno's 1984 Sharks of the World, and is also consistent with his and Fowler's more recent Princeton guide on sharks. Compagno's generally considered authoritative on the subject of sharks. The common thresher's presence in the Black Sea is also listed by the FAO and in FishBase. I'm not saying that your sources are not authoritative, but we here on Wikipedia are not the ones to make the call on which one to believe. Still, rather than simply striking the entire map (which is still useful) from the article for this relatively minor contention, might I suggest simply modifying the map, or adding a brief note about the uncertainty to the article? -- Yzx (talk) 16:50, 9 March 2009 (UTC)[reply]
