Nephrops norvegicus

Nephrops norvegicus is a burrowing marine decapod crustacean native to the northeastern Atlantic and Mediterranean. It is commonly called the Norway lobster or langoustine.

Decapoda: An order of crustaceans with five pairs of walking legs, including crabs, lobsters, and shrimps. Nephrops belongs to this order, whose defining leg arrangement frames its body plan.
Ecdysis: The periodic shedding of an arthropod's outer covering to permit growth. A new, larger exoskeleton forms after each molt.
Nephrops fishery: Commercial harvesting of Nephrops norvegicus, mainly with trawls and creels. This fishery is the principal direct human use of the species.
Fishing mortality: The rate at which fishing removes individuals from a population. Harvesting is a major source of mortality in exploited Nephrops populations.
Nephropidae: A family of marine decapods that includes clawed lobsters and related species. This is the family that contains Nephrops and its closest clawed-lobster relatives.
Trophic ecology: The study of feeding relationships and energy transfer among organisms. Nephrops is both a predator of small animals and prey for larger predators.
Bottom trawling: A fishing method that drags a net along or near the seabed. Trawling captures Nephrops but can disturb the sediments surrounding its burrows.
Bycatch: Animals unintentionally caught while fishing for other target species. Nephrops trawls can capture fish and other seabed animals alongside the target catch.
Burrowing: The construction or occupation of shelters below a surface, including seabed sediment. Nephrops spends much of its life in sediment burrows with multiple entrances.
Scavenging: Feeding on dead or decaying organisms rather than killing all food directly. It supplements its diet by consuming carrion on the seabed.
