American lobster population, habitat preferences shifting, study finds

Scientists found that from 1995-2021, occupancy of boulder habitats by lobsters dropped 60%. Meanwhile, the number of lobsters residing in sediment or featureless ledge habitats increased 633% and 280%, respectively. Lobster population density across all types of habitats declined too, but the mean size of an adult lobster was greater in 2021 than in 1996.
