Abstract

Hemoglobin occurs widely amongst the invertebrates. Its presence in the largest of the animal phyla, the Arthropoda, is curiously limited; it is found in only a few insects and in four subgroups of crustaceans, the Branchiopoda, Ostracoda, Copepoda and Cirripedia (2). Branchiopod hemoglobin, a large extracellular protein, has been extensively studied, both structurally and functionally (3, 4, 5). No comparable studies describing hemoglobins from the other crustacean groups are available. We are, therefore, investigating an extracellular hemoglobin from the rhizocephalan cirriped, Briarosaccus callosus, a barnacle which is parasitic on the red king crab, and we report some preliminary observations of this unusual pigment.
