The occurrence and food habits of ctenophores
in New Jersey inland coastal waters, Biol.
Gelatinous phytoplanktonic organisms (jellyfish, siphonophores, ctenophores
, pteropod mollusks, salps [thaliaceans]) can change the ionic balance within their tissues and so regulate their buoyancy.
Relative predation potentials of scyphomedusae, ctenophores
and planktivorous fish on ichthyoplankton in Chesapeake Bay.
The main features of bristle groups as described in Mnemiopsis may therefore be characteristic of the apical organs in many, if not all, ctenophores
However, we do appreciate that some of our standard marine invertebrate phyla are evidenced during the late Precambrian: sponges early on, then diploblastic organisms such as ctenophores
and cnidarians, and later, early molluscs, flatworms, and possibly arthropods.
Also imaged were a variety of invertebrate plankters, ranging from copepods and larvaceans to ctenophores
and medusae to invertebrate larval types, such as echinoderm pluteus.
Lipid biomarkers and trophic linkages between ctenophores
and copepods in Svalbard waters.
Comb jellies, the ctenophores
, are life forms that resemble jellyfish.
In addition, he prepared all the preliminary sketches and finished paintings of about 70 nudibranch mollusks and 12 polyclad turbellarians, and the preliminary sketches of a few ctenophores
, a sea cucumber, and a crab.
Barnes and Crisp 1956; El-Komi and Kajihara 1991), a bryozoan (Hughes 1989; but see Hunter and Hughes 1993), spirorbid polychaetes (Gee and Williams 1965; Beckwitt 1982), ctenophores
(Pianka 1974), asteroids (Strathmann et al.
Why should there be as many as 1,000 species of midwater fishes, probably thousands of species of deep sea pelagic copepods, 200 kinds of mesopelagic medusae and ctenophores
, or even 20 species of deep-water squids?
Included in the new assemblage of more than 1,000 specimens are the first representatives of modern chaetognaths (arrowworms) and ctenophores
I recently discovered that the statocyst of ctenophores
has an asymmetric architecture related to the sagittal and tentacular planes along the oral-aboral axis.
Over the last three decades, frequent jellyfish blooms have been recorded in the oceans, resulting from population increases of cnidarians and ctenophores
(Mills, 2001; Purcell et al, 2007; Brotz et al, 2012).
