He begins by describing the renal components and their functions, and then describes how they are developed and used by elasmobranchs, osteichthyans, cyclostomes, amphibians, reptiles, birds, and mammals.
Nevertheless, prey remains from elephant seal stomachs show that they feed on a variety of epi- and mesopelagic, bioluminescent cephalopods, teleosts such as Pacific Hake, Merluccius productus, crustaceans, elasmobranchs, cyclostomes, and tunicates.
Jackson and McKinney (1990) found that, in the Mesozoic and Cenozoic, communication among zooids was more extensive in cheilostomes than in cyclostomes and that cheilostomes largely replace cyclostomes, which implies a trend in mean degree of individuation for bryozoans as a whole.
Stenolaemates, including the cyclostomes, form their skeletons almost entirely of low-Mg calcite; mineralogical complexity is provided by the gymnolaemate cheilostomes (Smith et al.

The switch from cyclostomes to cheilostomes, in both species dominance and abundance of indivi duals, has been drastic, although abundance is slightly decoupled from taxonomic richness (Fig.
In future studies, we should use these probes to isolate endostyle-specific genes from cephalochordates, cyclostomes, and hemichordates.
