1967a): On the sipunculid
fauna of the littoral of Cuba.
In the stomachs of both species, crustaceans and teleosts were the dominant prey items, and molluscs, polychaetes, echinoderms, and sipunculids
were found in lower abundance.
Natural cytotoxic activity of sipunculid
leukocytes on allogenic and xenogenic erythrocytes.
Sipunculus nudus has high activities of AK in its somatic tissues (van Thoai et al.
Fauna associated with the sipunculid
Phascolion strombi (Montagu), especially the parasitic gastropod Menestho diaphana (Jeffreys).
A characteristic of this sipunculid
is the presence of a large number of circulating mucociliary cells, or urn cell complexes (UCCs), within its coelomic cavity (Catacuzene, 1928).
(Reipschlager and Portner, 1996), mussels (Michaelidis et ai, 2005), crabs (Carter et al.
macronemus feed over sand like other mullid fishes, thrusting the pair of sensory barbels on the chin into sand to reveal the usual prey of small crustaceans, polychaetes, and sipunculids
, and cephalopods were found with high importance in summer samples.
Chondrites could have been produced by polychaetes, sipunculids
or even arthropods (Osgood, 1975; Savrda, 1992), although traditionally this ichnogenus is interpreted as made by sessile vermiform organisms that explored the surrounding substrate with a retractile proboscis-type organ or another tubular appendage (Simpson, 1957; Shourd and Levin, 1976).
Kyukichi Kishida (1888-1968) was a Japanese zoologist who studied morphology and systematics of various groups of animals including spiders, mites, pseudoscorpions and other arachnids, myriapods and insects, as well as sipunculids
, birds and mammals.
Besides the prey groups mentioned for kelp bass, the diet of barred sand bass were sipunculids
, cumaceans, and echinoderms.
Phylum 3 Sipuncula (Sipunculans, Sipunculids
, Peanut Worms)
Animals were separated into their major groups: annelids, crustaceans, mollusks, nemerteans, ophiuroids, sipunculids
, and others and put on aluminum pans.
Available evidence across various aquatic phyla, including annelids, sipunculids
, molluscs (bivalves and gastropods), crustaceans, and fish, supports the view that impaired oxygen supply capacity in aquatic ectotherms is the primary thermal limitation at low and high temperatures (Portner 2002, Portner et al.
