For entoprocts and small brachiopods (Novocrania anomala and Macandrevia cranium), whole-body tissue was employed; for larger brachiopods (Glottidia pyramidata, Hemithris psittacea, and Laqueus californicus), extractions focused on mantle and muscle; for the solenogaster (a.k.a neomenioid) aplacophoran mollusc Proneomenia custodiens, unhatched juveniles were used.
Although the SSC may have the best known marine fauna in Brazil (Migotto & Marques, 2006), at least 14 species found, 9.8% of the total, are new records (four polychaetes, two ascidians, one cnidarian, one bryozoan, one barnacle, two entoprocts and three mollusks).
Experts thought that Cotyledion tylodes may have belonged to the jellyfish-like cnidarian group, but new anatomical evidence from the animal's fossilised remains suggests the species was an early member of the group of small marine organisms called entoprocts.
2008), entoprocts (Fernandez-Leborans & Gabilondo 2006, Fernandez-Leborans & Gabilondo 2008), nematodes (Normant et al.
Representatives of some phyla also share a trochophore larval stage (e.g., some polychaetes, sipunculids, vestimentiferans, echiurans, entoprocts, and molluscs).
An exception to this are the trochophores of polyplacophoran molluscs and the creeping-type larva of entoprocts, which both have a highly complex apical organ with 8-10 central flask cells surrounded by numerous peripheral cells, a condition that seems to occur only in these two clades (Friedrich et al., 2002; Voronezhs-kaya el al., 2002; Wanninger et al., 2007; Wanninger, 2008; Fig.
The larval apical organs of chitons and entoprocts include a centrally localized group of eight flask-shaped cells and additional peripheral cells that send fibers into a central neuropil (Voronezhskaya et al., 2002; Wanninger et al., 2007).
This idea might also apply to other spiralian taxa such as molluscs and entoprocts. As their development is similar, they should be subject to similar effects of endodermal volume on midgut morphogenesis.
(1972) and Strathmann (1978)--bivalves, annelids, echiurids, sipunculids, and entoprocts. In this system both preoral and postoral rings are essential for filter-feeding by the larva (Strathmann et al., 1972), and provide an efficient mechanism to capture particles.
