lobster : any of a family (Nephropidae and especially Homarus americanus) of large edible marine decapod crustaceans that have stalked eyes, a pair of large claws, and a long abdomen and that include species from coasts on both sides of the North Atlantic and from the Cape of Good Hope — Webster
Lobster comprise a family (Nephropidae, sometimes also Homaridae) of large marine crustaceans. They have long bodies with muscular tails, and live in crevices or burrows on the sea floor. Three of their five pairs of legs have claws, including the first pair, which are usually much larger than the others. Although several other groups of crustaceans have the word “lobster” in their names, the unqualified term “lobster” generally refers to the clawed lobsters of the family Nephropidae. Clawed lobsters are not closely related to spiny lobsters or slipper lobsters, which have no claws (chelae), or to squat lobsters. The closest living relatives of clawed lobsters are the reef lobsters and the three families of freshwater crayfish. — Wikipedia

Why North Carolinian boats are fishing off New...

As the oceans warm in response to climate change, fishing boats in the Mid-Atlantic that focus on only one or two species of fish are traveling more than 250 miles farther north than they did 20 years ago, while others catching a wide diversity of species have not changed fishing location, reported Talia Young, a postdoctoral research associate in ecology and evolutionary biology at Princeton.

Flip a lobster on its back, and you'll see that the underside of its tail is split in segments connected by a translucent membrane that appears rather vulnerable when compared with the armor-like carapace that shields the rest of the crustacean. […]

Have you ever wondered what's going through your dog's mind when you say the word "walk"? And does your pup seem to show guilt when you ask them sternly "what have you done?" Their tail might drop between their legs, their ears droop down, and their eyes turn away. […]

The detection of physical forces is one of the most complex challenges facing science. Although Newton solved the problem of gravity long ago, imaging the physical forces that act within living cells remains one of the main mysteries of current biology. Considered to play a decisive role in many biological processes, the chemical tools to visualize the physical forces in action do not exist. But today, researchers from the University of Geneva (UNIGE) and the National Centre of Competence in […]

Researchers at the University of Sydney and the Sydney Institute of Marine Science have found that climate change could lead to declines of underwater kelp forests through impacts on their microbiome. […]
