#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.

#Fouling means that #sessileanimals as #crustaceans or #mussels attach themselves to non-living #underwatersurfaces as #shiphulls. According to Capt. Raghu Sharma (2026), this particularly affects ships beyond the #StraitofHormuz due to #warmwaters and #highsalinity. It increases #hydrodynamicdrag leading to higher #fuelconsumption (M. Tadros et al. 2022).

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."

The ancient creature was up to 1.1 m long and probably lived in a marine-influenced #estuary fed by a river delta. Its diet likely included small #crustaceans, #ostracodes, #conchostracans, #invertebrate #larvae and #gastropod eggs.
