A group of lobsters is commonly referred to as a “mob” or a “lounge.”
This term, while not as widely known as some other collective nouns, reflects the nature of lobsters and how they might congregate. Lobsters are social creatures, often seen gathering in rocky crevices or undersea ledges, particularly during mating seasons. The term “mob” suggests a sense of group movement and interaction, while “lounge” implies a more relaxed gathering, akin to how lobsters can often be found resting together in their habitat.
