#crustaceans — Public Fediverse posts

#Crustaceans at Elberry Cove included European Edible Crab (Cancer pagurus), Rockpool Prawn (Palaemon elegans) & Northern Acorn Barnacle (Semibalanus balanoides). Also a lovely Snakelocks Anemone (Anemonia viridis). #UKWildlife #UKNature #MarineLife #crustacean #crab #nature #wildlife #crabs #invert

💁🏻‍♀️ TIL: 🦞🎒 #US #Fish and #Wildlife biologists are testing tiny photo-IDs attached as "backpacks" to #endangered Big Sandy #crayfish in #Appalachia.

Because injecting a #chip would harm the 10 cm (4 in) #crustaceans, researchers superglue a batter-free PIT tag to each #shell and set it with baking soda water. The setup was first tested on a common surrogate species, and the tags letting go are actually a sign the crayfish survived long enough to molt.

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.

Divers have already spotted carnivorous #sponges that capture small #crustaceans, a surprising find for habitats once thought sparse.

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).

Here's a lobster boi! Drawing those big claws was really fun (but also quite difficult to get right with perspective)

💁🏻‍♀️ 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.

Learning how to draw shrimps. How do people keep track of all their legs??? (There's so many...)

That said they do look kinda cute haha

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" 🤦‍♂️.

Sally Lightfoot crab (Grapsus grapsus)..Galápagos Islands, west coast Americas...its name is said to come from its ability to run in all four directions...those back ridges serve a purpose, helping reinforce the exoskeleton against crashing waves. #wildlife #nature #crustaceans #science #ecology #photo

Male Fiddler Crab (genus Uca, Austruca or Tubuca). They have an unusual diet, they're detritivores. They use the small claw to scoop up mouthfuls of sediment, sift out the algae and microbes, and then spit the sand back out in little pellets. #wildlife #nature #biology #crustaceans #photo

Lobsters and crabs should not be exploited in any way, but there are at least five ways that their exploitation during farming can be considered especially cruel. 🦞🦀 https://veganfta.com/blog/2026/03/17/5-examples-of-the-cruelty-of-lobster-and-crab-farming/ #lobsters #crabs #crustaceans

🦀🛡️ In the #ChesapeakeBay, the biggest threat to a young blue crab isn't a hungry #fish – it's another blue crab.

A long-term study explains that while these #crustaceans are notoriously cannibalistic, juveniles have a better chance of surviving if they stick to the ultra-shallow waters of coastal estuaries where bigger #crabs can't easily reach them.

One of the highlights of my day was when William Harland, a talented ecology undergrad here at #LincolnUniversityNZ, stopped by my office to show me his photos of temnocephalid flatworms. These distinctive squat tentacled flatworms live in colonies on NZ's freshwater crayfish, koura, and eat scraps left over when the koura feed. They apparently cause no bother to the koura.

William found these at Poolburn Reservoir in central Otago.

Amazing!

Woodlouse are #Crustaceans in the #Order Isopoda. They are NOT insects! With slightly under forty species here; it's worth learning to identify species. Common Pill Woodlouse (Armadillidium vulgare) seen in #Brighton by @[email protected] has both grey and orange colour forms. #brightonwildlife

"One day, perhaps, she might create a crab that’s incredibly well suited to domestication—the golden retriever of hermit crabs, if you will. But are they meant to live in our homes at all?"

“#Nature has so far balanced our abuse. This is coming to an end,” - #JohanRockström, director of the Potsdam Institute for #ClimateImpact Research.

#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."

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."

#Nanospheres in the organs reflect light that matches the color of surrounding water. The spheres are a bit like disco balls, with highly reflective surfaces pointing outward. These balls are arranged in clusters at the base of protein-dense cones that focus light on the animal’s light-sensing nerves, and form a protective cover over the pigmented cells.
