Lobster Western rock, Panulirus cygnus

Arsenobetaine was the first arsenic compound identified in a marine animal when it was isolated in 1977 in a crystalline form from the tail muscle of the western rock lobster Panulirus cygnus (48). The large body of work that followed established that arsenobetaine was by far the predominant form of arsenic in marine animals (Table VI). It occurs at all trophic levels, although there is a tendency for it to be present at higher concentrations (or at least constitute the greater percentage...
