Ctenophora (/ təˈnɒfərə / tə-NOF-ər-ə; sg.: ctenophore / ˈtɛnəfɔːr, ˈtiːnə -/ TEN-ə-for, TEE-nə-; from Ancient Greek κτείς (kteis) 'comb' and φέρω (pherō) 'to carry') [6] comprise a phylum of marine invertebrates, commonly known as comb jellies, that inhabit sea waters worldwide.

2010年11月8日 · This book includes an introduction to the Ctenophora and descriptions with color or black-and-white photographs of 28 species of west coast ctenophores, most of which are also found elsewhere in the world.

2022年2月1日 · We developed the design of a laboratory experiment to reveal the light-induced behavior of adult Mnemiopsis leidyi from the Black Sea and identified criteria for its evaluation. Average swimming speed up to ~6–7 mm s −1 can be considered specific for the M. leidyi adults under rest or active feeding.

Ctenophores (phylum Ctenophora), also known as comb jellies, are marine invertebrates that have eight rows of comb-like cilia on their transparent, gelatinous bodies. They are the largest animal to use cilia for locomotion. Superficially, ctenophores resemble jellyfish, which belong to the phylum Cnidaria. Indeed, the Ctenophores and the ...

Interestingly, the ctenophore was introduced to the Black Sea in the early 1980s in ship ballast water. Due to their generalist diet on a variety of zooplankton species, they outcompeted the native fishes, leading to the rapid decline of commercially important fish species.

Anthropogenic introduction of exotic species into the Black Sea, either accidentally or intentionally, began in the 19th Century, but the greatest problems occurred during the latter half of the present century.

2016年11月10日 · The temperature rise in the Black Sea in May up to 16°C leads to B. ovata early appearance, but ctenophore luminescence values are low in the spring period. The first ctenophore bioluminescence peak is observed in July.

2023年10月6日 · So, to sum it up, for the first time for the Black Sea invasive ctenophores, the ecological role of bioluminescence has been shown. Ctenophores have been discovered to resort to bioluminescence if it is necessary to send a fast directional signal over short and medium distances, using luminescence as a means of interspecific interactions in the ...

2024年2月29日 · The abundance, biomass, distribution, and feeding patterns of the ctenophore Mnemiopsis leidyi A. Agassiz 1865 were studied in the deep-water Black Sea in October 2019. The biomass of the ctenophore in the open sea areas was 100–200 g m–2, and the abundance was 16–38 ind. m–2.

2010年10月5日 · Ctenophores are basal metazoans that may be the earliest diverging extant multicellular animal lineage . Unlike fish and copepods, ctenophores do not use vision or other remote detection mechanisms to increase encounter rates with …
