From the Kumamoto International Desk of Things You’d Rather Not Know: The sea cucumber (ナマコ, namako) defends itself by expelling sticky fibers from its anus. As a diver, I’ve learned to avoid them, but one man’s gross-out is another’s delicacy. (My son loves namako.)
Kumanichi reports that namako processing in Ushibuka is peaking. Guts are pickled and bottled, while the flesh is served as sashimi. “There is not one part of the namako which is disposed of,” the chairman of the Ushibuka Fisheries Cooperative said. Comforting about this is the fact that you won’t encounter various namako parts while out and about. - William
