How does a crustacean become a crab?
Crabs are living the meme life on social media lately. The memes joke that everything will eventually look like a crab. But it's actually based in some truth......»»
Study reveals evolution of crab group Thoracotremata
Thoracotremata (Brachyura, Decapoda) is the most derived crab group, encompassing 1,248 extant species. It currently comprises four superfamilies: Grapsoidea MacLeay, Ocypodoidea Rafinesque, Cryptochiroidea Paulson and Pinnotheroidea De Haan......»»

No air currents required: Ballooning spiders rely on electric fields to generate lift
The work could lead to new types of ballooning sensors for atmospheric exploration. Enlarge / Image from a 2018 observational study of ballooning in large spiders depicting a crab spider just as it is about to take off. (credit: Cho, M.....»»
The "Platypus" of the crab world was an active predator that lurked the Cretaceous seas
Eyes are crucial players in the evolution of organisms. They allow an animal to find food, a mate, potential prey, to avoid predators and aid in regulating the internal clock by differentiating day from night. Eyes are also delicate features that ten.....»»
A crab"s-eye view of the ancient world
Their legs may get more attention, but a new study says a crab's eyes have much to offer, too—at least scientifically......»»
Tesla Cybertruck to feature crab mode, quad-motor option at launch
Tesla's flagship Cybertruck (tri-motor) can go from 0 to 60 mph in a mere 2.9 seconds and offers over 500 miles of driving range, leading many to refer to it as one of a kind......»»
Study finds that ancient penis worms invented the "hermit crab" lifestyle
A new study by researchers from Durham University and Yunnan University reveals that penis worms (Priapulida) invented the 'hermit' lifestyle, some 500 million years ago, at the rise of the earliest animal ecosystems in the Cambrian period......»»
Trapped in amber: Fossilized dinosaur-era crab bridges evolutionary gap
Discovery pushes back when crabs came to land, freshwater to 100 million years ago. Enlarge Once upon a time, during the Cretaceous period, a tiny crab wandered out of the water onto land and somehow got trapped in amber, whi.....»»
Researchers discover first dinosaur era crab fully preserved in amber
Fossils trapped in amber provide a unique snapshot of the anatomy, biology, and ecology of extinct organisms. The most common fossils found in amber, which is formed from resin exuded from tree bark, are land-dwelling animals, mainly insects. But on.....»»
Understanding how a crab"s complex life cycle will respond to climate change
For many marine animals, like the Dungeness crab, seasonality and timing are components of complex life cycles, where disruptions can have serious implications for the population. Understanding how climate change will impact each life stage is no sma.....»»
Cracking the blue crab"s genetic code
Scientists at the University of Maryland Center for Environmental Science have sequenced the genome of the blue crab. The best way to understand an organism is to understand its genetic makeup, also known as its genome. Once the code is understood, i.....»»
Valuable crab populations are in a "very scary" decline in warming Bering Sea
Federal biologist Erin Fedewa boarded a research vessel in June in Dutch Harbor, Alaska, and journeyed to a swath of the Bering Sea that typically yields an abundance of young snow crab in annual surveys......»»
Astronomers solve centuries-old mystery of supernova observed in 1181

On Earth, things evolve into crabs—could the same be true in space?
Evolution experts were kind enough to answer Ars' questions about alien crabs. Enlarge / It sure looks like a crab, but it isn't. Why are crab-like forms so common? (credit: David Kirkland / Design Pics) Many organisms on planet Earth aren't c.....»»
Environmental change impacting some Queensland fisheries
A collaborative research project to identify and measure the effects of environmental drivers on several key Queensland fishery species—snapper, pearl perch, and spanner crab—has drawn to a close......»»

LHAASO measures Crab Nebula brightness, yields new UHE gamma-ray standard
The Large High Altitude Air Shower Observatory (LHAASO), one of China's key national science and technology infrastructure facilities, has accurately measured the brightness over 3.5 orders of magnitude of the standard candle in high-energy astronomy.....»»
Unusual currents explain mysterious red crab strandings
For decades, people have wondered why pelagic red crabs—also called tuna crabs—sometimes wash ashore in the millions on the West Coast of the United States. New research shows that atypical currents, rather than abnormal temperatures, likely brin.....»»
A New Type of Supernova Unlocks Old Stellar Mysteries
The discovery of a rare “electron-capture” supernova provides crucial insight for understanding the Crab Nebula......»»
New crab species with asymmetrical reproductive units identified
A team of researchers from the National University of Singapore (NUS) and the University of the Ryukyus has recently identified and described a bizarre new genus and species of xanthid crab found on Okinawa Island, Ryukyu Islands, Japan. Named Mabui.....»»
