Nephropidae, commonly known as lobsters, are marine crustaceans found in the ocean's rocky and sandy substrates. They have long bodies, muscular tails, and large claws, with some species exhibiting striking colors. Lobsters are primarily nocturnal scavengers, playing a crucial role in maintaining healthy marine ecosystems by feeding on dead organisms.

Nephropidae, commonly known as lobsters, are primarily found in the marine waters of the Atlantic Ocean. Their distribution ranges from the cold waters of the North Atlantic, including the coasts of North America from Canada to North Carolina, to the warmer waters of the Mediterranean and parts of the eastern Atlantic including parts of Europe and North Africa.

Lobsters inhabit coastal waters and are typically found on the ocean floor. They prefer rocky, sandy, or muddy substrates where they can find shelter in crevices or burrow into the sea floor. The water temperature in their habitats generally ranges from 12°C to 22°C (54°F to 72°F), though they can be found at depths ranging from the intertidal zone to about 480 meters (1,570 feet) deep.

Lobsters are benthic creatures, meaning they live on the ocean floor. They play a significant role as both predators and prey within their ecosystems. Lobsters feed on a variety of marine organisms such as fish, mollusks, and other crustaceans, contributing to the control of these populations. Their ability to regenerate lost limbs is an adaptation that helps them survive in their competitive and predator-rich environments.
