ROVs support research ranging from studies of undersea landslides caused by the 1989 Loma Prieta earthquake to the behavior of delicate gelatinous animals like ctenophores
and the distribution of cold-seep communities in the bay.
Predation mortality of bay anchovy Anchoa mitchilli eggs and larvae due to scyphomedusae and ctenophores
in Chesapeake Bay.
For example, ctenophores
don't use serotonin, dopamine and other common signaling chemicals, called neurotransmitters.
The occurrence and food habits of ctenophores
in New Jersey inland coastal waters, Biol.
These were the big ctenophores
that you see in the Pacific.
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.
Comb jellies, the ctenophores
, are life forms that resemble jellyfish.
Lipid biomarkers and trophic linkages between ctenophores
and copepods in Svalbard waters.
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.
Macroinvertebrates--primarily jellyfish, squid, ctenophores
, and salps--although often abundant in the catch, were not consistently identified or counted and therefore are not included here.
Also, similar to the tubes described here, the Devonian tubes were located in the median deflection of brachiopod shells (Chatterton 1975) and were interpreted as commensal and/or parasitic in origin, possibly caused by activity of polychaetes, tunicates, cnidarians, ctenophores
, or arthropods.
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
, larvaceans and pteropods ([E.
hispidus were observed pursuing and nipping at lobate ctenophores
