But it is conceivable that the now utterly lost branchiae might have been gradually worked in by natural selection for some quite distinct purpose: in the same manner as, on the view entertained by some naturalists that the branchiae and dorsal scales of Annelids are homologous with the wings and wing-covers of insects, it is probable that organs which at a very ancient period served for respiration have been actually converted into organs of flight.
Cornulitids have been affiliated with annelids, tentaculitids, microconchids, cnidarians, molluscs, bryozoans, and phoronids (Fisher 1962; Boucek 1964; Blind 1972; Dzik 1991; Vinn & Mutvei 2005; Vinn 2005, 2006).
Numbering over 15,000 described species, annelids are diverse and ecologically important members of marine and terrestrial communities worldwide (Struck et al., 2011).

Particles that have reached the mouth can be rejected in a strand of mucus that passes posteriorly, along the developing foot in molluscs or the neurotroch of annelids, but this means of rejection, if prolonged, involves loss of mucus, and also the drag from a trailing mucous strand could increase capture of particles (Emlet, 1990; Fenchel and Ockelmann, 2002; Strathmann and Grunbaum, 2006).
The Western Terrestrial Garter Snake (Thamnophis elegans) is a versatile predator on a diverse spectrum of animal species, including aquatic and terrestrial mollusks (snails, slugs) and annelids (polychaete worms, leeches, earthworms), intertidal marine crustaceans (small crabs), terrestrial arthropods (insects, spiders), and members of every vertebrate class, especially amphibians and fish, less often reptiles, small mammals, and birds (Cunningham 1955; Campbell 1969; White and Kolb 1974; Anderson 1977; Gregory 1978; Kephart and Arnold 1982).
