The mitochondrial genome of the
sipunculid Phascolopsis gouldii supports its association with annelida rather than mollusca.
and the
sipunculid Aspidosiphon gosnoldi were quite abundant in stations of Group III, the first species in those stations situated at the north mouth of the channel (13, 14 and 15), and the second species at station 9 in summer (84 individuals) and winter (100 individuals).
In the autumn, both adults and juveniles relied more on crustaceans, with also a marked increase in the presence of
sipunculid worms.
The remaining 9% comprised crustaceans, echino-derms, tunicates, and a
sipunculid (see Appendix).
In the first, a specialist on
sipunculid worms was asked for copies of his publications by an Alaskan cod fisherman.
In marine invertebrates, such as annelid worms,
sipunculid worms, and molluscs, the presence of an AOX has been described; nevertheless, to date there are no reports of this enzyme in crustaceans (McDonald et al.
Simitar events, which involve the shedding or histolysis of the larval epidermis variously called "serosa" or "test," occur during development of some other spiralians, for example the stenocalymma larva of the scapho-pod mollusc Dentalium (Lacaze-Duthiers, 1856; after Buckland-Nicks et al., 2002), the test larva of neomen-ioid aplacophorans (Thompson, 1960: Okusu, 2002), and the pericalymma of the protobranch bivalve molluscs (Gustafson and Reid, 1986; Gustafson and Lutz, 1992; Zardus and Morse, 1998), as well as the unusual larva of the
sipunculid Sipuncultts nuchts (Gerould.
The mitochondrial genome of the
sipunculid Platscolopsis gouldii supports its association with Annelida rather than Mollusca.
The MBL's Supply Department provided the animals that he used in his comparison of marginal bands: the
sipunculid and polychaete worms, lobsters and crabs, horseshoe crabs, some blood arcs, the skates, and of course the dogfish.
Coelomocytes from
sipunculid worms have been shown to participate in immune responses such as phagocytosis and cytotoxicity against foreign agents (Boiledieu and Valembois, 1977; Blanco et al., 1995, 1997; Cabrera et al., 2002).
