A lecithotrophic larva, called cyphonautes is typically present in Phylum Ectoprocta. Classification of Phylum Ectoprocta: The Phylum Ectoprocta is divided into two classes.
Suggestions for classification and division essay topics When it comes to classification essay topics, there are a lot to choose from. Here are some good examples.

The phylum is commonly divided into three taxa, the articulate Rhynchonelliformea and the two inarticulate clades Craniiformea and Linguliformea ( 4 ), and has traditionally been grouped together with Phoronida and Ectoprocta into the superphylum Lophophorata.Read More
The larvae of gymnolaemates have been broadly grouped into three types, cyphonautes (shelled, feeding), pseudocyphonautes (shelled, nonfeeding), and coronate (unshelled, nonfeeding), although each group is heterogeneous and probably includes various morphologies that are largely undescribed.Read More
This chapter provides explanations that are dependent upon a particular and special ecologic or taxonomic history. Because relative uniformity of the environment reinforces specialization and leads to speciation, any given character complex, or lineage, will, on the average appear through time to go from the r to the K end of the spectrum.Read More

Background. Two theories for the origin of animal life cycles with planktotrophic larvae are now discussed seriously: The terminal addition theory proposes a holopelagic, planktotrophic gastraea as the ancestor of the eumetazoans with addition of benthic adult stages and retention of the planktotrophic stages as larvae, i.e. the ancestral life cycles were indirect.Read More
In amphipods, morphological adaptations for feeding provide taxonomic evidence that helps to differentiate them into species. Intuitively, this indicates that the morphology of feeding structures may be related to the type of food the amphipods consume, and that their distribution would depend on the distribution of their food. These hypotheses were examined using zooplankton collections from.Read More

The ovum in its young condition is obviously nothing but a simple cell; and such it remains till the period when it attains maturity. Nevertheless the changes which it undergoes in the course of its growth are of a very peculiar kind, and, consisting as they do in many instances of the absorption of other cells, have led various biologists to hold that the ovum is a compound structure.Read More
It contains chapters on the discovery of bryozoans, their morphology, classification and fossil history, their roles in biosecurity and marine benthic environments, and potential uses in biotechnology and ocean acidification. It provides an authoritative reference for biology students, academics and others interested in marine biology.Read More
