Gregarious behaviour in #Carboniferous cyclidan #crustaceans https://royalsocietypublishing.org/doi/10.1098/rsbl.2024.0734
"With legs emerging from underneath rounded shells, #cyclidans looked not unlike an underwater beetle. Earliest species were a few mm in size and form #fossils that look like a tiny bunch of grapes. Over millions of years they evolved larger species, and by the #Triassic they were about as wide as a human hand"

El Cangrejo Rojo (Grapsus grapsus adscensionis) más adorable que he podido fotografiar. Reconozco que, aún sabiendo el tamaño que llegan a coger, me sorprendió.

#MantisShrimp clubs filter sound to mitigate damage https://phys.org/news/2025-02-mantis-shrimp-clubs-filter-mitigate.html
Does the mantis shrimp pack a phononic shield? https://www.science.org/doi/10.1126/science.adq7100
"Their fists, or dactyl clubs, are covered in layered patterns, which selectively filter out sound. By blocking specific vibrations, the patterns act like a shield against self-generated shockwaves."
New supergiant 'Darth Vader' sea bug discovered in South China Sea — and it's absolutely massive
"The giant isopod has been named Bathynomus vaderi due to its resemblance to Darth Vader's iconic helmet from "Star Wars."

“probably the freshwater shrimp Cryphiops caementarius, which can grow to ~ 7 in. long and is still found in the rivers of Peru.”

At least you didn't call it a "crab-like" as "Live science" did.
#Amphipods are not #shrimps (ok, one group is called "skeleton shrimps", but they don't even resemble shrimps tbh. and Dulcibella is not from that one).
And this thing looks pretty normal for deep-water Amphipods:

Crabs and lobsters can feel pain!
Before eating them, #people should also consider that many #crabs & #lobsters are significantly older than they are.

Meet Strawberry Claws—a new species of hermit crab https://phys.org/news/2024-11-strawberry-claws-species-hermit-crab.html
A new species of #HermitCrab in the genus #Strigopagurus from the continental shelf off south-east #Queensland, #Australia https://www.museum.qld.gov.au/collections-and-research/memoirs/nature-65/mqm-n65-7-davie-mcnamara
"the #NewSpecies has several highly distinctive features. Most striking is its bright red claws, but it also has evolved its own unique method of producing underwater sound (#stridulation), much like #cicadas do in the air."
This constant rewriting and reshuffling clades around is why no one likes taxonomists!

we need good #Taxonomy )
An important reorganization of Pancrustacea (#crustaceans, #insects & friends) with some interesting #evolutionary implications.
This is going to be one of these papers that will lead to a lot of "hum... actually" to students on what they learned in secondary school (as well as old graduates).

Absolutely massive, lobster-like signal crayfish in the river Misbourne. These species were brought to the UK from North America to be farmed, but have escaped into the wild & infiltrated some of the UK’s wild rivers, where they are pushing out the smaller native species from their habitats.

#Trees and #land absorbed almost no #CO2 last year. Is nature’s #CarbonSink failing?
The sudden collapse of carbon sinks was not factored into #ClimateModels – and could rapidly accelerate #GlobalHeating
by Patrick Greenfield, October 14, 2024
"It begins each day at nightfall. As the light disappears, billions of #zooplankton, #crustaceans and other marine organisms rise to the ocean surface to feed on microscopic #algae, returning to the depths at sunrise. The waste from this frenzy – Earth’s largest migration of creatures – sinks to the #ocean floor, removing millions of tonnes of #carbon from the atmosphere each year.
"This activity is one of thousands of natural processes that regulate the Earth’s climate. Together, the planet’s oceans, forests, soils and other natural carbon sinks absorb about half of all #HumanEmissions.
"But as the Earth heats up, scientists are increasingly concerned that those crucial processes are breaking down.
"In 2023, the hottest year ever recorded, preliminary findings by an international team of researchers show the amount of carbon absorbed by land has temporarily collapsed. The final result was that #forest, plants and soil – as a net category – absorbed almost no carbon.
"There are warning signs at sea, too. #Greenland’s Glaciers and #ArcticIceSheets are melting faster than expected, which is disrupting the #GulfStream ocean current and slows the rate at which oceans absorb carbon. For the algae-eating zooplankton, melting sea ice is exposing them to more sunlight – a shift scientists say could keep them in the depths for longer, disrupting the vertical migration that stores carbon on the ocean floor."

"Although it’s not clear exactly what gives each #cave its unique smell, the researchers hypothesize that compounds released by #sponges that live in the #caves are playing a role."

"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."
