Abstract

We determined the sulfation patterns and the amount of chondroitin sulfate in several tissues of the diamond squid, Thysanoteuthis rhombus. Every tissue contained the highly-sulfated E type of chondroitin. The arms, skin, and fin had non-sulfated chondroitin as the homogenous polymer. The skin and fin possessed larger amounts of chondroitin sulfate per unit of weight than the other tissues.
