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

First steps to tackling South Africa's abalone...
on November 22, 2018 at 12:19 pm
South Africa faces the possible collapse of several inshore fisheries, particularly certain species of linefish, abalone and West Coast Rock Lobster. If nothing is done, not only will the ecology be poorer and change in many unexpected ways, but sea-derived livelihoods will collapse. The social structures that have maintained communities and relationships with the sea will follow. […]
Building the ultimate record of the ocean
on November 22, 2018 at 10:14 am
Before the advent of modern observational and modeling techniques, understanding how the ocean behaved required piecing together disparate data—often separated by decades in time—from a handful of sources around the world. In the 1980s, that started to change when technological advancements, such as satellites, floats, drifters, and chemical tracers, made continuous, mass measurements possible. […]

Restoring the United States' lands and coastal wetlands could have a much bigger role in reducing global warming than previously thought, according to the most comprehensive national assessment to date of how greenhouse gas emissions can be reduced and stored in forests, farmland, grasslands, and wetlands. […]

For the most part, the mature Atlantic cod is a solitary creature that spends most of its time far below the ocean's surface, grazing on bony fish, squid, crab, shrimp, and lobster—unless it's spawning season, when the fish flock to each other by the millions, forming enormous shoals that resemble frenzied, teeming islands in the sea.

Commercial shellfish landings decline likely...

Researchers studying the sharp decline between 1980 and 2010 in documented landings of the four most commercially-important bivalve mollusks—eastern oysters, northern quahogs, softshell clams and northern bay scallops—have identified the causes. […]
