#crustaceans — Public Fediverse posts

💁🏻‍♀️ TIL: 🛸🌊 A #NOAA #ROV explores abyssal plains near the #CookIslands in the #SouthPacific, mapping the deep seafloor and #water column with sensors while live streaming nearly daily through August 13. Divers have already spotted carnivorous #sponges that capture small #crustaceans, a surprising find for habitats once thought sparse.

💁🏻‍♀️ TIL: 🦐🚀 Scientists at the #Okayama University of #Science used a specialized high-speed spinning #machine to simulate weightlessness for kuruma shrimp and sea monkeys.

The team observed that while the larger #shrimp needed mesh netting to steady themselves, the smaller brine shrimp thrived and grew normally over several days. The #research provides a look at how #future #astronauts might raise #aquaculture setups on the #Moon.

💁🏻‍♀️ TIL: 🏛️🟢 When the #LincolnMemorial #ReflectingPool turned green with #algae after a $15 million renovation, officials reached for #chemicals and expensive #technology.

But a #freshwater ecologist explains that #nature offers cheaper, longer lasting solutions. Tiny #crustaceans called #Daphnia and rooted aquatic #plants can control algae by consuming it and absorbing nutrients before blooms form.

Antarctic #krill can lock away similar levels of #carbon as #seagrass, #mangroves https://phys.org/news/2024-09-antarctic-krill-similar-carbon-seagrass.html

Antarctic krill sequester similar amounts of C to key coastal #BlueCarbon habitats: Emma Cavan et al. https://www.nature.com/articles/s41467-024-52135-6

"Krill are extremely numerous #crustaceans that live around #Antarctica. They eat #algae that take carbon out of the atmosphere by photosynthesis. When krill poo or molt their exoskeletons, the carbon sinks into the #DeepSea where it can stay for a very long time."

Researchers reveal how genetically identical #WaterFleas develop into different sexes https://phys.org/news/2024-05-reveal-genetically-identical-fleas-sexes.html paper: https://www.nature.com/articles/s41598-024-59774-1

"#Daphnia are tiny #crustaceans, or water fleas, that are extremely adaptable to their environment. This is due to their remarkable phenotypic plasticity, i.e., their ability to change their form or behavior despite their genetic makeup remaining unchanged. Even male and female Daphnia are genetically identical."

Chondrocladia Sponge
https://interactiveoceans.washington.edu/05/2024/chondrocladia-sponge/

"A bizarre and rarely-seen carnivorous #DeepSea sponge, Chondrocladia lampadiglobus (colloquially known as the ping pong tree sponge) can be seen growing on stalks anchored in the sediment of the #abyssal #ocean... They have a modified version of the internal water flow system found in shallow-water #sponges, but they use it to inflate the round balloon-like structures that capture prey (usually small #crustaceans) using hooked spicules."

Today, I found a vernal pool bustling with tiny, freshwater ostracods (order Podocopida). Each is about the size of a pinhead.

Decades-old #crustaceans coaxed from lake mud give up genetic secrets revealing #evolution in action

Resurrection #genomics provides molecular and phenotypic evidence of rapid adaptation to #salinization in a keystone aquatic species https://www.pnas.org/doi/10.1073/pnas.2217276120

They revived decades-old #Daphnia resting eggs from lake sediments. Tanners Lake has suffered significant salt #pollution, stemming from the widespread use of road deicing salts in its watershed.
