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.
Parandalia bennei (Pilargidae) and Spiophanes lowai (Spionidae) new species of polychaetous annelids
from Mazatlan Bay, Pacific coast of Mexico.
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).
. Scientific Results of Cruise VII of the Carnegie during 1928-1929 under the command of Captain J.P.
Mammals, reptiles and toads constitute the prey items of terrestrial species while fossorial species feed on annelids
, molluscs, arachnids, myriapods, hexapods, amphibians, reptiles and mammals.
The bones were kept on board ship in aquaria with filtered seawater at 12 [degrees]C, and Protodrilus annelids
were sampled from the surfaces of the vertebrae.
Abstract: The taxonomic location of the Onychophora has been controversial because of their phenotypic and genotypic characteristics, related to both annelids
Gills of hydrothermal vent annelids
: structure, ultrastructure and functional implications in two alvinellid species.
New polychaetous annelids
from Laguna Beach, California.
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).
