Rare all- blue crab do­nated to Sul­tana

Kent County News - - NEWS -

CH­ESTER­TOWN — An ex­tremely rare, com­pletely blue crab of the species Callinectes sapidus was do­nated to Sul­tana Ed­u­ca­tion Foun­da­tion Oct. 1 by waterman Jamie White.

Ac­cord­ing to a news re­lease from the Sul­tana Ed­u­ca­tion Foun­da­tion, the crab was caught off of Rock Hall. Its color rep­re­sents a ge­netic ab­nor­mal­ity that can oc­cur in crus­taceans, the re­lease states.

“I pulled it up and I thought it was spray painted,” White said.

White do­nated the all-blue crab to Sul­tana Ed­u­ca­tion Foun­da­tion so that pro­gram par­tic­i­pants can get a close look at the rare crus­tacean. Although all blue crabs have some amount of blue pig­men­ta­tion on their shells, this ex­am­ple is most likely an ex­tremely rare ge­netic mu­ta­tion that has al­tered the amount of cer­tain pig­ments in the shell.

Al­bino, orange and even pur­ple crabs have been re­ported in the Ch­e­sa­peake Bay in the past, as well as “mo­saic” crabs, which are one color on part of their body, ac­cord­ing to the re­lease.

The all-blue crab, which is a 6-inch ma­ture male, is cur­rently re­sid­ing in one of the brack­ish wa­ter fish tanks in Sul­tana Ed­u­ca­tion Foun­da­tion’s Ch­ester­town Holt Cen­ter wet lab. It ap­pears in good health and seems un­aware that is truly is a “once in a blue moon” crab, the re­lease states.
