Unlike other hermit crabs, these extraordinary crustaceans do not search for empty shells to settle in for protection. Instead, they have developed a symbiotic relationship with sea anemones to cover their soft bellies. To do this, the crabs use highly specialized chelipeds to pull back and forth the anemone's ...
Some of the ocean's tiniest creatures may be creating powerful jets of water that profoundly alter the Earth's environment. By studying brine shrimp that measure just a few millimeters long, researchers at Stanford University discovered that small sea creatures can produce shockingly large-scale effects ...

But those of well-endowed ancient crustaceans? Much more tragic. According to a new study published in science journal Nature, ostracod species with massive junk were more likely to go extinct than their less-blessed peers. To quote professor and study author John Swaddle, ostracods were “the Don ...
Gene Hunt at the National Museum of Natural History in Washington DC and his colleagues studied the fossil record of small, chalky-shelled crustaceans called ostracods, some of which survive today. To accommodate their sex organs, the males' shells are more elongated than the females', making it easy ...
Fisheries that targeted smaller open sea fish, on the other hand, contributed only 2 per cent of the sector's emissions despite accounting for a fifth of all reported landings. Previous research has suggested that fisheries targeting crustaceans consume substantial quantities of fuel while catching relatively low ...
Understanding various facets of the global crustaceans market, Persistence Market Research has come up with an analytical research publication titled “Crustaceans Market: Global Industry Analysis (2012-2016) and Forecast (2017-2025).” The comprehensive crustaceans market research report focuses ...

It's no secret that male and female animals tend to differ in their appearance. Human males are larger on average than human females, for instance, to a degree consistent with what's observed in other primates. Sometimes, as with peahens and their strutting peacock counterparts, the divergence can be ...
Hidden over 1,000m underwater along the Sunda Strait off the coast of Jakarta is a peculiar spider crab with plates resembling ears that actually protect its eyes. It had not been seen for some 10 million years, till researchers from Singapore and Indonesia discovered it while trawling the depths of the sea ...
Market Research Report Search Engine (MRRSE) recently announced the addition of a new research study to its comprehensive collection of research reports. The research report, titled “Global Market Study on Crustaceans: Direct Distribution Channel to Witness High Growth Potential in the Years to ...
Switzerland's decision is applauded by Professor Robert Elwood, emeritus professor in ecology, evolution, behaviour and environmental economics at Queens University, Belfast. Elwood has conducted a series of experiments that suggest crustaceans are sentient and that boiling them alive is inhumane.
Professor Emeritus Robert Elwood's made the comments after Switzerland became the first country to ban the common cooking practice as part of new reforms to the country's animal welfare laws. The scientist, who has carried out extensive research on how decapod crustaceans experience pain, has ...
The self-cloning crustaceans exploded amongst Germany's aquarium hobbyists in the 1990s. Now it has become an invasive species in countries as far away as Japan and Madagascar. Marbled crayfish (picture-alliance/dpa/R.Andrian). The government of Canada warned the public on Sunday not to keep ...
Crustacean reproduction is a complex process, which implies the ovarian growing in adult females during the critical period previous to spawning (named as a pre-reproductive period). During this period, the immature (previtellogenic) oocytes develop into mature (vitellogenic) oocytes, which accumulate a ...
While researchers are discovering lobsters are more complex than previously thought, there remains a boiling debate about whether the crustaceans actually feel pain. "You can't ... They, like lobsters, are arthropods, a group of invertebrate animals that includes both insects and crustaceans. She doesn't ...
“If stunned electrically or if the brain is destroyed mechanically they are effectively dead,” Robert Elwood, an ecology professor at Queen's University Belfast who has studied crustaceans for decades, previously told Newsweek via email. “They would not recover consciousness if left in an attempt to do so.” ...
More than 50 high-profile campaigners have signed a letter to Michael Gove, the environment secretary, calling on him to recognise the crustaceans as animals. Under current Animal Welfare laws in Britain, decapod crustaceans aren't classed as animals and therefore aren't covered by the Animal Welfare ...
More than 50 high-profile campaigners and celebrities have called for stronger protection to prevent lobsters and crabs being cooked alive. They have signed a letter urging Environment Secretary Michael Gove to categorise the crustaceans as sentient organisms in a new Animal Welfare Bill.

The studies were conducted by Professor Robert Elwood, emeritus professor in ecology, evolution, behavior and environmental economics at Queens University, Belfast. His experiments indicated that crustaceans will make serious life and death decisions when exposed to pain. Hermit crabs, for example, ...
Aquariums gurgle inside closed labs as Wes Dowd navigates the marine science wing of Heald Hall. Dowd, an associate professor of environmental animal physiology, will spend the next three years studying copepods, microscopic crustaceans that live in intertidal pools. He will research how their unique ...
In addition to this, live crustaceans, including crabs and lobsters, will no longer be transported on ice or in ice water but kept in their natural environment. These new laws are in accordance with studies and arguments that show lobsters can feel pain, making it inhumane to cook them in such a manner that ...
There's no reason to think the crustaceans feel pain, crustacean expert Greg Lutz said. “Psychologically, there is no reason to believe or expect that a crustacean has the nervous system to process and feel pain. They simply are not equipped with that. A crustacean's nervous system is a lot like an insect's ...
Only after one of these methods can lobsters, crabs and other crustaceans be placed into boiling water to cook. And Switzerland isn't the first place to decide a more humane lobster death should be required. Death by boiling is already illegal in New Zealand and in northern Italy's Reggio Emilia. In addition ...
The Swiss government has enacted a new law banning the practice of boiling lobsters alive. As of March 2018, any lobsters (or other crustaceans) being prepared for a meal in Switzerland must be stunned or killed humanely before they are boiled. The basis of this law is Switzerland's official recognition ...
Furthermore, they may no longer be transported on ice, or in fresh water: they have to be kept in salty water, as close as possible to their natural environment. From 1st March, lobsters - and other crustaceans - will have to be stunned before cooking, either by electric shock or by mechanical destruction of ...
Boiling lobsters alive — a common practice for cooks transforming the popular crustaceans into a meal — will soon be illegal in Switzerland. The Swiss government ruled last week that lobsters must be stunned before they are cooked and kept in a natural environment rather than on ice or in ice water.

Lobsters are a delicious delicacy loved by coastal dwellers across the world — but is boiling them alive inhumane? In a new law, the Swiss government has banned the common culinary practice of throwing the crustaceans into boiling water while they are still conscious. The move is a response to studies ...
“Live crustaceans, including the lobster, may no longer be transported on ice or in ice water. Aquatic species must always be kept in their natural environment. Crustaceans must now be stunned before they are killed,” according to the new Swiss law, which will take effect in March. A similar law came into ...
One man's work to minimise the devastating impact fishing litter can have on the marine environment has been recognised with a national award. John O'Connor has campaigned to keep Pembrokeshire's coast free of lost or discarded fishing tackle which can entangle crustaceans, birds and seals as well ...

New Jersey has now joined a compact with most other states to share information about people who violate hunting laws, allowing states to revoke licenses for violations in other ...
In turn, these species rely heavily on populations of Antarctic krill -- small, shrimp-like crustaceans. Krill are harvested commercially and are a key ingredient of nutritional supplements, aquaculture feed, and other products. As such, leopard seals, penguins and fur seals not only are important components of ...
Most of these species are probably “macro” sized (1 mm to 10 cm) seabed-living crustaceans, molluscs and worms. We've found just over 6,000 new marine crustaceans and almost 8,000 marine molluscs in the past ten years. A recent finding of 28 new amphipod crustacean species doubled the number of ...

Not least, there's the challenge of capturing the crustaceans in the wild. Also known as stomatopods, mantis shrimps live in burrows in shallow seawater and have earned the descriptive nickname “thumb splitters,” thanks to their tendency to use their sharp, powerful claws to slash at prey and pursuers.
These waters are mysterious and difficult to study, but so far scientists know the depths are home to amphipods and other crustaceans, sea cucumbers, jellyfish, and tiny one-celled organisms called foraminifera. Now, we know the deepest waters are also home to the Mariana snailfish. This two-inch-long, ...
