It has been suggested that comb jellies such as the ctenophores are ancestors of all life on earth. ❋ Unknown (2009)
More than 600 million years ago ctenophores—common and fragile jellies with well-developed tissues—were probably the first off the blocks when multicellular life began to diversify. ❋ Martin A. Nowak (2011)
The loss of apex predator biomass could trigger a broad expansion in the biomass of ctenophores, jellyfishes, squid and small pelagic fishes (sardines, anchovies, etc.). ❋ Unknown (2008)
The ctenophores are capable of a high degree of sensory discrimination and remarkably complex behavior patterns, suggestive of a unified awareness and intentionality, but there is no evident anatomical basis for assuming that such an individuality actually exists. ❋ Unknown (2007)
Consider the ctenophores, the comb jellies for example, a much more complex organization than the porifera, being comprised of a number of highly specialized and interdependent cell-types. ❋ Unknown (2007)
In echinoderms as in ctenophores, cellular interaction is entirely discrete and reflexive. ❋ Unknown (2007)
Where ctenophores may be said to have approached the limits of cooperative social organization, echinoderms – starfish, for example – have achieved a highly effective consolidation of decentralized hierarchies of coordination. ❋ Unknown (2007)
It's also very well preserved, and has features that suggest affinities to the ctenophores. ❋ Unknown (2006)
If you take a look at animal phylogeny, an important group are the diploblastic phyla, the cnidarians and ctenophores. ❋ Unknown (2006)
I was under the opinion that ctenophores differed from cniderians because of the presence of a third layer; perhaps not a true mesoderm but not diploblastic in the same sense that cniderians are. ❋ Unknown (2006)
Well, we have the simple visuals -- when we look at the water, and swim in the water, we see far fewer fish, and far more ctenophores and cnidarians jellyfish. ❋ Mariness (2005)
When dozens of these _ctenophores_ (or comb-bearers) as they are called, glide slowly to and fro through a pool, the sight is not soon forgotten. ❋ William Beebe (1919)
If a fine silk net is drawn through the water and then emptied into a glass dish a whole new world of creatures will be revealed -- jellyfishes, ctenophores, hydroids, eggs of fish, tiny copepods, the larvae or young of sea-urchins, starfishes, or oysters. ❋ Girl Scouts Of The United States Of America (1918)
In addition to sharks enjoying the currents that roar through the area, pelagic drifters like ctenophores can be found in large numbers. ❋ The Huffington Post News Editors (2011)
The mesopelagic fauna also includes many kinds of squid, krill, and siphonophores and ctenophores (jellyfish-like animals), as well as worms, sea butterflies, and larvae that comprise the DSL zooplankton. ❋ Unknown (2010)
Prey include amphipods, copepods, mysids (shrimp-like animals), other small crustaceans, small mollusks, small jellyfish and ctenophores, larvae of other invertebrates and in some cases small fish. ❋ Wanderin' Weeta (2010)
Census scientists sampling the Black Sea, for example, found blooms of tiny comb jellies (ctenophores) vacuuming up all available nourishment, while minute copepods (crustaceans) dominated parts of the North Atlantic. ❋ Unknown (2010)
