Active Predators: Unlike microscopic plankton that passively filter algae, ctenophores are voracious carnivores, using sticky cells called colloblasts to capture smaller zooplankton, larval fish, and even other comb jellies. So while they are technically plankton by lifestyle, they are one of the most evolutionary fascinating, visually breathtaking predators drifting in the water column!

Light Specialists: That stunning rainbow glow in Pete Harmsen's photograph isn't bioluminescence; it's diffraction. As their cilia beat to move them through the water, they scatter light into a brilliant, shifting spectrum.

Master Swimmers: They are the largest animals in the world to move using cilia (microscopic hair-like structures). Rows of these cilia, called "comb plates," beat in synchronized waves to propel them.

Iridescent ctenophore by Pete Harmsen

Ctenophores (comb jellies) are technically classified as gelatinous zooplankton, but they are extraordinary creatures in several key ways:

Pioneers of the Animal Kingdom: Phylogenetically, ctenophores are among the oldest animal lineages on Earth, having diverged long before complex fish or crustaceans evolved.

#ElNino is disrupting the Pacific’s marine food web from the bottom up

"The ecological consequences of this #nutrientdecline would mean less food available for #zooplankton, as well as for fish, seabirds, and marine mammals, the NASA Earth Observatory article said. This affects fisheries: Peru’s anchovy fisheries, for example, saw significant declines in catch during previous El Niño events, driven by warmer surface waters, reduced upwelling, and lower phytoplankton levels. This year, the country has repeatedly suspended its vital anchovy fishery to protect vulnerable fish stocks, while starving pelicans have begun invading urban ports in search of food."

In der #Lagune von #Venedig breiten sich invasive #Arten wie die kannibalische #Rippenqualle und die #Blaukrabbe durch wärmere #Meere aus.

Beide bedrohen das #Ökosystem und verringern die Fänge deutlich. #Qual­len fressen #Zooplankton sowie Eier und Larven wichtiger Arten. #Blaukrabben finden ganzjährig ideale Bedingungen und schädigen heimische #Muscheln und #Fische. Behörden suchen nach Wegen, die Folgen für Natur und regionale #Fischerei zu begrenzen.

Edward Smith Deevey Jr. (3 December 1914 – 29 November 1988), born in #AlbanyNewYork, was a prominent American #ecologist and #paleolimnologist, and an early protégé of #GEvelynHutchinson at #YaleUniversity. He was a creative pioneer in several areas, including quantitative #palynology, cycling of natural #isotopes, #biogeochemistry, #populationDynamics, #systematics and #ecology of freshwater #zooplankton, and he promoted the use of life tables in ecology. In 1938.

A new IGB study shows just how sensitively #zooplankton respond to dam construction. In the White #Nile, decades of regulation have halved species diversity. With the new Grand Ethiopian Renaissance Dam (#GERD), the Blue Nile may now face similar losses in #biodiversity.

Tiny creature gorges, gets fat, and locks up planet-warming #carbon
These "unsung heroes" called #zooplankton gorge themselves and grow fat in spring before sinking hundreds of metres into the deep #ocean in Antarctica where they burn the fat.
This locks away as much planet-warming carbon as the annual #emissions of roughly 55 million petrol cars, stopping it from further warming our atmosphere, according to researchers.

Seit 2013 gibt es im Greifswalder Bodden deutlich weniger Nahrung für #Heringslarven.

Ursache sind klimabedingte Verschiebungen im #Nahrungsnetz. Die Larven schlüpfen früher, finden aber zu wenig #Zooplankton und verhungern.

Auch höhere #Wassertemperaturen setzen ihnen zu. Der Rückgang des #Heringsnachwuchses gefährdet
#Fischbestände in der westlichen #Ostsee.
