Giant, deep-sea roly-polies steal a #gene to endure starvation
The football-sized #crustaceans feast when they can, then slow their #metabolism to a crawl
These #Isopods are armored, oblong crustaceans. Long ago, the creatures stole a gene from a bacterium and welded it into their own set of DNA. This may help the crustaceans tolerate extremely long periods without food in the frigid, abyssal desert.

Crabs invade garden shed… 50 miles from the sea https://www.allforgardening.com/1854264/crabs-invade-garden-shed-50-miles-from-the-sea/ #BBCThreeCountiesRadio #bedfordshire #Biggleswade #crustaceans #garden #HitchinStreet #MichaelBirch #RichardLawrence

💁🏻‍♀️ 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.

#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).

💁🏻‍♀️ ICYMI: 🦐🦘 Roly polies are terrestrial #crustaceans that evolved from marine-dwelling ancestors.

They share a specific trait with #kangaroos because both carry their young in a brood pouch. Female pill bugs carry their #eggs and newly-hatched young in a special pouch called a marsupium.

Ah yes, the riveting saga of #isopods globe-trotting from #Madagascar to #Montenegro 🌍🦐. Who knew these unassuming #crustaceans had a more robust #travel itinerary than even the most pretentious Instagram influencer? If only booking a vacation were as simple as listing continents and calling it a "site" 🤦‍♂️.

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."

For #WoodlouseWednesday, an isopod molting!

All arthropods (which includes crustaceans like isopods, plus insects, spiders, and more) molt to grow bigger. Isopods molt in two stages, one end at a time.

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.
