Ctenophora were readily identifiable in the stomachs of spiny dogfish, at sea upon macroscopic inspection, by their obvious firm-gelatin constitution, small and clear ball-like shape, uniquely (relative to any other spiny dogfish prey) colored pinkish-gray masses, and particularly the ctene rows.

Conversely, embryos that incorporate multiciliated cells into specialized swimming structures (e.g., ciliated bands or ctene rows) might be expected to take longer to construct their swimming apparatus than embryos that swim with simple, uniciliated cells.

Evolution of fast development of planktonic embryos to early swimming

For example, previous chalk-particle marking experiments indicated that the eight rows of comb plates in ctenophores are derived from the four [e.sub.1] micromeres of the 16-cell embryo (7), and deletion of these four micromeres results in the absence of ctene rows and their associated endodermal canal system (8-10).

Evolution of cleavage programs in relationship to axial specification and body plan evolution

One characteristic set of structures displayed by most adult ctenophores are the eight longitudinal rows of comb plates (comb or ctene rows) that are used for locomotion.
