Newly discovered genus and species of crabs named after two of the main characters of J.K. Rowling's Harry Potter.
Scientists reported on Wednesday that Birgus latro, the largest land-dwelling crab in the world, are so strong that it can pinch at about 750 pounds of force (3,300 newtons) and even lift 66 pounds.
Despite lacking an area of the brain that is equivalent to what enables human to sense pain, crabs are capable of feeling pain, researchers confirm.
Dangerous levels of domoic acid, a naturally occurring neurotoxin from algal blooms, have been detected in Dungeness and rock crabs caught along the coast of California.
Climate change could warm ocean water temperatures to the point where king crabs could migrate to shallower Antarctica waters, drastically altering marine fauna along the continental shelf and causing widespread reduction in biodiversity.
Great diversity, reproductive action, and seabird feeding was taking place in the pitch-dark, three consecutive winters that researchers recently spent in the Arctic Circle. In their report, they talk about the wisdom of allowing human industry into a very busy, and rare, wildlife region.
Graduate students from the Scripps Institution of Oceanography at the University of California-San Diego discovered a methane seep about 30 miles off the coast. This site is home to many unique, adaptable species, and is the first found in the region.
Toxins from algal blooms in the Chesapeake Bay may affect human and marine species' health.
It's a red coastline in Southern California as hundreds of thousands of red tuna crabs invade beaches, brought to the region by warm ocean currents, officials said Wednesday.
There are two new vampire crabs being added to the roster, and yes, there is really a roster of vampire crabs. What's unusual about these new discoveries, however, is that while they are new to science, they have been residents of some home aquariums for a pretty long time.
Here's a strange aquatic animal that you've probably never heard of: the frog crab. No, it's not some horrific amphibian-crustacean hybrid cooked up by mad scientists. Instead, it's just one very odd looking crab, characterized by an unusually flat and frog-like body. Now researchers are investigating the evolution of these strange and poorly understood creatures.
The coconut crab is a crustacean behemoth that normally makes the Indian Ocean islands its stomping grounds. It has no business stalking the streets of Honolulu. However, that's exactly what one crab was found doing this holiday week. Now it will spend its New Year's Eve locked up on the vacation island.
"Hey, I'm a synchronized dancer," has never been the best of pick-up lines, and now we know why. A recent study of fiddler crabs has revealed that their characteristic synchronized mating dances to attract a female are all about being off-beat, where the crab that dances most unlike the others is twice as likely to get the girl.
It has long been suspected that rising temperatures and ocean acidification are making it harder for crabs to reproduce and survive. However, aside from weakening exoskeletons, it was unclear exactly why this was happening. Now, a new study suggests it comes down to these crustaceans' own biology.
