Sally Hall, a PhD student at the University of Southampton's School of Ocean and Earth Science (SOES) at the National Oceanography Centre, Southampton (NOCS) has formally described four new species of king crab, all from the deep sea.
Hall discovered the new species in the Smithsonian Collections of the National Museum of Natural History in Washington. Explaining the significance of the find, she said: "King crabs include some of the largest crustaceans currently inhabiting Earth and are fished by humans, particularly from the shallower waters of the polar regions. The new discoveries increase the total number of king crab species known to 113."
The new species are Paralomis nivosa from the Philippines, P. makarovi from the Bering Sea, P. alcockiana from South Carolina, and Lithodes galapagensis from the Galapagos archipelago – the first and only king crab species yet recorded from the seas around the Galapagos Islands. P. nivosa and P. makarovi came from previously unidentified samples collected in the early part of the twentieth century by the US Bureau of Fisheries steamer, Albatross.
King crabs were first formally described in 1819. They are now known from subtidal waters at high latitudes, but deep-sea species occur in most of the world's oceans, typically living at depths between 500 and 1500 metres.
"We are only now beginning to understand the incredible diversity of animals living in the deep sea," said Hall: "It is incredible that the Albatross collection is still yielding new information, even though it is over 100 years since this survey of deep-sea life began."
It is now clear that species of deep-sea king crab live in most areas of the world's oceans, but many more species remain to be discovered. "The oceans off eastern Africa, the Indian Ocean and the Southern Ocean are all particularly poorly sampled," said Hall: "We need to know which king crab species live where before we can fully understand their ecology and evolutionary success."

The National Oceanography Centre, Southampton is the UK's focus for ocean science. It is one of the world's leading institutions devoted to research, teaching and technology development in ocean and earth science. Over 500 research scientists, lecturing, support and seagoing staff are based at the centre's purpose-built waterside campus in Southampton along with over 700 undergraduate and postgraduate students.
The National Oceanography Centre, Southampton is a collaboration between the University of Southampton and the Natural Environment Research Council. The NERC royal research ships RRS James Cook and RRS Discovery are based at NOCS as is the National Marine Equipment Pool which includes Autosub and Isis, two of the world's deepest diving research vehicles.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
