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

- Births among endangered right whales highest...on April 3, 2021 at 8:57 pm
North Atlantic right whales gave birth over the winter in greater numbers than scientists have seen since 2015, an encouraging sign for researchers who became alarmed three years ago when the critically endangered species produced no known offspring at all.

A new study has found the first evidence of sophisticated breathing organs in 450-million-year-old sea creatures. Contrary to previous thought, trilobites were leg breathers, with structures resembling gills hanging off their thighs.
- Seagrasses turn back the clock on ocean...on March 31, 2021 at 4:58 pm
Spanning six years and seven seagrass meadows along the California coast, a paper published today from the University of California, Davis, is the most extensive study yet of how seagrasses can buffer ocean acidification.
- Climate change ravages coralligenous architects...on March 18, 2021 at 2:21 pm
Marine heatwaves are dramatically affecting the marine ecosystems of the world and the Mediterranean is no exception. In the Mediterranean, these extreme climate episodes and its resulting massive mortality of species are getting more and more intense and frequent. To date, most of the studies analyzed the effects of these perturbations on specific species and populations, although researchers still do not know how this affects the functioning of the involved ecosystems.
- When 'eradicated' species bounce back with a...on March 15, 2021 at 7:00 pm
Some invasive species targeted for total eradication bounce back with a vengeance, especially in aquatic systems, finds a study led by the University of California, Davis.
